  1. This bus exists for the riders. If a BART train is arriving at the station and it is 8:01, the bus should wait for the riders from BART instead of pulling out on the stroke of 8:02. This happened two days in a row. These buses can easily make up a minute en route. Leaving several riders to wait 20 mins for the next one when in actuality, they would have made the bus if it had waited for the stroke of 8:03, is frustrating for us who are taking this bus. The last bus, 8:38, should also wait until the stroke of 8:39. I will also call the Stanford transportation dept w this complaint.

  2. Today I’m heading to the Stanford oval for the DB and was surprised that the bus was taking off at 3:52pm rather than 3:54pm. I have been catching this bus since the December change. I ask thank the bus driver for waiting as I ran to catch it and asked”the bus no longer departs the Oval at 3:54pm?” His was reply was “No the schedule chane it’s 3:52pm now.” So I puzzled, I check the DB website, the paper schedule and the Stanford transportation site. And I do t see anything that supports the schedule change. I’m very concern has a passenger who is dependent on public transportation. If there has been a change the communication needs to be better. If there has not been a schedule change please talk to your bus driver of Bus 96004 on 01/31/13. I would like some type of response back. Thank you!

  3. DB left Stanford Oval today Friday February 1st 2013 at 4:33pm! It is scheduled to leave at 4:37pm! I was almost at the bus stop and the bus driver drove away! Please ensure that bus drivers leave on the appropriate designated time a listed on the bus schedule.


  4. Arrived at Stanford Oval at 303pm…Bus #96003 (license 8U83618) had engine running for 20+ minutes. No sign of 305pm departure bus from Stanford Oval. Bus #161 just arrived…and has now left again. Because 305pm bus was a no-show or no-go, the bus is completely full leading up to PA Caltrain. Very unfortunate that 305pm is not on-time or on NextBus grid.

  5. I waited an hour hr for my bus in Palo Alto the last 2 weeks, the bus was to be at my stop at 7:15, the DB2, showed an hr late. I would appreciate you guys tell us that you change your schedule on Fridays

  6. On Mar 26th, the 9:52 bus westbound to Palo Alto is NO SHOW at Union City Bart Station!!!

    You DON’T just cancel the bus without notifying or any ride alert!

    What a crap!

  7. You don’t just cancel one ride and let people wait for one fucking hour!
    8:52 bus is no show at union city Bart station!

  8. I have to say this is the least reliable bus service I have ever had to use. My morning ride to work is great, but it is always a gamble on the way home. I’m never sure if the drivers will be on time or if they will even stop where they are supposed to. When they do stop, I’m never sure of the treatment I will receive. I have complained and, each time, things may improve for a day or two, but then it’s right back to normal. I wish there were some other way for me to get where I need to go. I would gladly use it.

  9. I arrived at the Bart station stop on Tuesday, June 11th at 5:18pm. Although I was almost 5 minutes early, the dumbarton express 1 line was no where to be found. After calling #511, I learned that it had already left. I rely on the schedules and would appreciate it if the busses remained on schedule. Thank you very much.

  10. Bus number 10 departing VA Palo Alto @ 3:28 pm. The driver is unprofessional, he spoke loudly to the trainee in his native tounge a majority of the ride and according to law employees are not to speak their native tounge unless the job requests for bilingual. He paid very little attention to the road and for the first 15 minutes of the ride he had the heat on. Finally when other passengers complained he turned on the air and focused on the road. I usually like riding the bus but today made me very nervous and scared.

  11. So I rode the DB bus today from Caltrain Station to Union City. I usually pay with my clipper card and this morning I paid with my clipper card so I know I still have 5 bucks in my card because it show your balance whenever you use your card. On my home, I scan my card and it beep twice and I know when it beep 2 different tone it’s a warning that you need to load your card for future use but the driver said when it beep twice you don’t have funds in your card and if it beep once your good to go! Please train your drivers, I mean other driver know it but it cost me almost 9 bucks. I just paid her AGAIN with cash because I don’t want to argue her.

  12. 7/17/13, the DB bus which departured at 0942 from Union city towards stanford oval was widely early than the schedule! On the schedule the bus should be leave Adenwood at 0956, but she leaved at 0951, 5 mins early. It should leave palo alto Caltrain at 1029, the bus leaves at 1018. 10 mins early than the schedule! Imagine those people depend on public transportation, they can’t catch the bus! Can somebody inquire that bus driver, why she was driving crazy fast, and off the schedule wild early? Hope it would not happened again! Pls respond to my email, I would like some respond. Thanks!

  13. The dumbarton express leaves EARLY from union city station. Stranding all of the passengers who get off the bart that arrives 1 minute before it takes off. This needs to be changed.

  14. License plate on bus is 1152588

    Female (overweight) bus driver driving rather badly on Deer Creek Road this morning at approx 9:05 a.m. between Arastradero and Page Mill roads in Palo Alto. I pulled out of Page Mill Pastures with plenty of room, she was way up the hill still, coming down towards Page Mill Riad, she didn’t bother trying to slow down at all to the speed limit, she drove up quickly behind me, tailgating me, and had to drive in the middle turn lane, almost alongside me as though she was going to try to pass me! Very reckless. Then, she stopped alongside me at the light so she could turn right on Page Mill, I was going to turn left, and we both visibly “yelled” at each other. Very poor performance representing your organization.

  15. Whoever the guy driver for the this morning was real rude to my kids they was standing at da door he closed it in there face and was gound to pull off on them til i got out of the car and my Daughter was like what but he looking at them the whole time.some of your drivers are just so rude if they some like there job then they need to find a new one.

  16. I take the Dumbarton Express db1 daily to work. The first rule of any public transportation should be reliability imho and db1 fails miserably. For example, db1 simply did not show up two times at the VA in Palo Alto where I work. This month, October, it no-showed 2 x. Per the drivers, the reasons presented were the bus mechanical problem and employees not showing up to work. There is also a particular driver whom us riders call “the maniac” whom ALWAYS drives wrecklessly, frequently yelling out at other drivers with insults and profanities, and almost caused accidents on several occasions. She is an accident waiting to happen, literally.

    My understanding is that many riders have called in and have complained to your managem7ent but was reportedly rebuffed.

    Let me make it clear that Dumbarton Express is a very poorly managed bus company. My message is this: if you cannot run it with minimal professionalism, get out of this business and leave it to someone who can.

    Mike Lee

  17. Seriously the bus for DB line today passed me…was in the 3rd lane like it didn’t even plan on stopping…now I’ll be late for work…awesome…

  18. How is it that the DB can charge patrons to ride buses that are leaking in at least a dozen areas on the inside??? This is not the first time this has happened!!!!! This is utter nonsense!!!!

  19. The DB eastbound bus headed towards Stanford university arrived at Ardenwood Park & Ride at 7:05am today.

    Everyone boarded and the bus closed the door and started to pull away. There was a girl who ran up to the bus right next to the door and yet the bus driver sill tried to drive away! And even said “she is about to run in front of the bus” when clearly the girl was on the side of the bus.

    For the year and a half that I’ve been taking DB, most of the drivers are nice enough to still let you board even if you’re not there right on time. Here, the driver didnt even turn around the Ardenwood lot yet! She just left the girl standing there and drove away. All of the passengers on board even asked why didn’t you let her board! The driver didnt say anything.

    Check your driver for April 2nd, 2014 DB scheduled bus driver from Union City Bart departure line at 6:52am.

    Dumbarton needs to reevaluate the attitudes and behaviors of drivers.

  20. When you use public transportation.itnsead of driving, riders depend on the bus being on time. There are 10 riders here at Uion City BART that are waiting for a bus that is over 20 minutes late. This is completely ridiculous!!!!

  21. Today, U was waiting for DB1 bus at Ardenwood Park and Ride and the bus that was supposed to be here at 7:51 didn’t show up. I had been waiting since 7:35 till 8:10. Then suddenly it showed up at 8:10. When I enquired the operator about the whereabout of the 7:51 bus, she very rudely replied, ” We are the 7:51 bus”.

    I think DB/DB1 are the worst managed routes of A/C transit. A lot of people living in EastBay and working in Palo Alto who are sensitive about global warming depend on these lines to go to work everyday. I sincerely request the management to take a look into the management of these routes and take appropriate action.

  22. DB your bus driver on 6/11/14 for the 6:55am departure from Union City towards Stanford (black woman driver) really needs to learn some common courteousy. She doesn’t park to the side of the stops and makes passengers get on the bus in the middle of the road. She’s also rude and one of the most unfriendly drivers. I’ve been taking DB everyday for year and a half and there has been more if not friendly but professional and courteous drivers. This is the same driver who pulled away without letting a passenger on the bus when the passenger was on time and te bus hasn’t even pulled away from the bus stop. DB your agency is a service provider of transportation to the commuters and exists for the passengers. Reevaluate your drivers and have them go through training, especially what it means to be service oriented and basic customer service needs of courteousy and professionalism.

  23. Can you please ask the driver to stop texting and driving. I am on the bus right now DB1 #163 at 9:22am on July 22, 2014 and the driver is constantly braking hard and causing the bus to jerk because she is constantly looking down at here phone. I have pictures and video to prove this and of something’s happens while I am on this bus you can expect a lawsuit.

  24. The 7:30 pm westbound bus on 8/13/14 that hits the Menlo Park VA Medical Center didn’t even bother to stop. It slowed down on Willow, as to think about it, and just kept on going. There were four of us clearly waiting.

  25. Hi I would to give my thoughts about riding the DB to and from Stanford hospital. I commute from San Leandro and my employer encourages me to use public transportation, to be green! So I have been, although almost every day I we are late the bus driver arrives 10min late and then takes his time to depart! This is not good for me nore the rest of the people who ride to work. I feel something needs to be done. Either a new driver or a few minutes earlier. The bus I am on know is #165 west bound and has come late again! Not to mention last night on my way back there was no 7:30 pm bus and the 8 pm was also late. I did not get home till almost 10pm I get off at 7:25. Please help us all so we continue to ride public transportation or we will be forced to drive in order to avoid being punished at work for arriving late. Thank you Sam

  26. Bus left ten minutes early 😡left 6-7 people usual passengers waiting. Very frustrating db can not get there timing right!!!!

  27. 10/1 11:39am bus is a no show.. got here 25 minutes early too so there’s no way I missed it due to it arriving early. It just never showed up.. What the hell?? I had an interview I needed to get to and this was the only bus that could get me there!!

  28. DB is not on time per the schedule you have on your website nor the schedule you have at the bus stop. Have some pride in your craft and show up for the task at hand.

  29. I’m a everyday rider. When can we expect weekend Sevice over the bay. I would greatly appreciate it. I work over the weekends. Thanks 4 your service through the week & maybe the weekends soon. Let me know of changes to happen. Thanks again, Ray V.

  30. The same bus driver , middle aged black man , has been late for many times. Today he arrived at Ardenwood park and ride at 6:09am instead of 6:05am. For us going to work, every minute counts.I hope somebody do solve this big problem.

  31. REALLY Really scary this morning on bus 647. With the driver screaming at passengers about his pay and how this fleet is the oldest in the east bay. And arguing with a passenger about the time table.

  32. Bus 160 at 6pm is driving prettt crazy, cutting people off, driving in turn lanes just to cut more people off

  33. Bus 160 at 6pm in menlo park is driving prettt crazy, cutting people off, driving in turn lanes just to cut more people off

  34. left home at 6:30 am to catch 7:26am bus at pal alto transit center and according to nextbus map it went through it. I did not see it though. next bus will be 8:42 which probably won’t show till after 9am. is it possible to have 8am bus instead of 8:42 and 8:56 which usually show up together after 9am ? my commute this morning is now 4hrs.

    thank you for your help.

  35. Today 4-7-11 the DB1 on Decoto and Ozark River Way going to VA Palo Alto left me. It was 6:22am when I’m walking from my car to the street and watch the DB1 ZOOM past me speeding. The bus was early, it did not wait and now I am late for work.
    How is it you arrive early, but don’t stop at the bus stop? I’ve been in the rain 45min. All cold and wet
    This was not acceptable.

  36. Please remind your bus drivers DB1 from Union City Bart to Palo Alto VA hospital there is a bus stop at Ozark River Way and Decoto River Way in Fremont.

  37. Is there a way to report a bus not running part of their route? The DB1 occasionally skips the Hillview loop (in front of VMWare/SAP), but passengers report that it is stopping at the VA.

  38. A driver was erratically driving across willow road towards the bridge at 6:40pm. She nearly ran several cars off the road forcing her way into a right lane without a blinker. Her information is bus 639, CA54849 and license plate 1018834.

  39. I am a regular user of the Dumbarton Bus line and I have been very disappointed on your service, especially recently. Your busses are rarely on time, you have new bus drives that dont consider the time table per designated bus stop, and last but not least your busses are extremely uncomfortable. I have been 30 minutes late for the past two weeks for work because of your untimely service and this is unacceptable.

    I suggest spending more time training your bus drives before you allow them to officially drive people, or have more consistency with those who manage to consider your time table.

  40. I want to say overall Dumbarton Express provides a good service . AM Dispatcher and GM are very helpful and provided me with excellent customer service.

  41. Waited from 7:11-7:57 on a Wednesday night. No bus came as scheduled. Had to take a cab home. Thanks a lot. Lost a customer.

  42. Db1 service in morning from Union city to Palo alto generally goes pretty well

    Unfortunately between the hours of 630to 8:00 its like there’s a service blackout in the eastward direction. There has literally not been single bus passing el Camino and page mill for the last hour. I would urge riders to not attempt to catch a bus between that time interval as you will be waiting until the very last bus

  43. The driver of the db 325 bus the number today was 640 is a horrific driver, she has been late the last 3 days. Yesterday we did not arrive to arden wood until 433. And that was NOT because of traffic. As a commuter 20 minutes makes a BIG difference in my commute. It delayed my commute to tracy almost 60 minutes. I have 2 kids one of whom HAS to be to football practice by 6 pm if not he hets punished by having to do harder workouts than the rest of the team. That is not fair he suffered yesterday due to your driver. Please do something with her.

  44. To whom it concerns;
    I am an avid rider and this tlist the last straw. The last two weeks I have been very disappointed with bus line. Buses have been very late especially on Mondays.Today is Wednesday 07/22/2015 and I arrived at the Palo Alto Transit stop #55003 only to fine that no bus came.I have been here for over an hour for a bus to arrive.I will not be using your service anymore.

  45. I ran to the stop in 90 degree weather, arrived 7 minutes early, only to have the DB pass me not once, but TWICE! I and another passenger have work commitments which we could not meet due to the poor customer service, lack of driver care, and poor bus design. Why are you running buses that stop picking up people??

  46. The buses take for ever to come and some of the drivers they have just need an attitude adjustment

  47. this is the second day this week our 4:32 bus has not shown up you are a terrible bus system you do not care about your customers I going to contact the BBB, and seven on your side and ask them to investigate this co.

  48. I was waiting for the last bus eastbound at the Palo Alto VA. I was standing outside in the dark and cold at 745, the bus never came by. I called db1 customer service and they said the bus driver drove by early. Let me tell you it was the last bus, so guess who was stuck in Palo Alto at night? Yes, me!! If a bus has a schedule why not be on time. There is no excuses when there is no traffic at night.i could understand a late bus but an early one??? 9/1/15


  50. If your going to complain you need to complain about something Dumbarton can fix . In a perfect world buses would always be on time but it’s not the drivers fault because some idiot can’t drive and gets into a accident on the bridge and now we are sitting into bumper to bumper traffic.

  51. There’s this one awesome driver who’s not only your most timely driver, but wears this super afro. He shows the utmost customer service skills, and he also greets people in different languages. And he’s really funny. He squashes potential problems with humor. And he really seems to like what he does for a living. Most of your drivers are pretty cool. But this one in particular is my favorite. I can’t remember his name to save my life right now. But he’s a really nice black guy with an afro.

  52. Some of these complaints are valid but seriously how can you blame the drivers for being late? It is the everyday commuter that doesn’t allow enough time to get to work and jumps into there car speeding to get to work on time and causes a accident. Traffic is traffic if you drive your car your not going to get to work any faster. You should allow enough time to get to work and leave your self plenty of time just in case there is a accident or some stupid construction going on

  53. The 808 bus this evening was passing cars on the right to bypass traffic on Willow. They were not pulling over for bus stops. This is dangerous.

  54. Was waiting on the db monday 10/05/15 on the corner of willow and newbridge and the bus came flying up willow with no intention on stopping,myself and the other two guys at the stop had too wave and scream to make him stop…your drivers are really terrible most of the time

  55. You whiners are disturbing. Do you think public transit is your personal servant? These bus drivers have to put up with traffic, the hot and cold conditions, crazy drivers, strict time points with following traffic laws and worst of all, rude passengers who want everything for nothing. You cheat on fares, complain about everything and LIE…try doing what bus drivers do, just once. I wish they could all come to your job and mess with you. Pick up 45 rude snotty people, load a wheelchair get stopped at every red light, sit in commuter traffic and annoying road construction…then get all 45 people to their destination safely.
    If it’s so bad, buy a freaking car and drive your own cry baby selfs to where you are going instead of messing and verbally abusing people and their difficult jobs. Hey crazy lady, call the BBB and the news, that would be hilarious to see you make a fool of yourself!
    Yes, buses run late. Every bus service does in the whole USA, hell even planes do. Do you bash them online? It’s a fact of life. Trains dont, no traffic and weather or roads to deal with.
    Find out facts, stop lying that a bus just blew right by you while you were exactly at the bus stop, thats crap. Stop bashing huma beings and try to understand just what they haveto put up with. Do something more construtive then hurt others.
    Unless of course all you people are honest PERFECT people?

  56. 10/13/15. 7:06pm bus from Stanford Oval to Union city never came again at Standord parking lot!! 7:31pm bus on time. 7:06pm bus always missing recently. I’ll keep track on this site from now on. Can DB management do something about it? I understand traffic sometimes make it harder, but late for 30 mins or not show at all?? Does that normal?

  57. I’ve ridden on Dumbarton Express many times. And despite all the negativity I see on here, “MY” personal experience with Dumbarton Express has been nothing short of Phenomenal. Your buses are comfortable, Drivers are nice. Though your buses are not always on time, that’s usually because of heavy traffic. Most of your DrIvers are pretty laid back, and a couple of them, are actually pretty funny. They need to have a sense of humor, for all that they deal with.

  58. turned out there was an incident on early DB and canceled. That affected 7:26am to delay for 30 min. She is skipping her breakfast to catch up. Sorry about that and thank you for doing that.

  59. Why is the DB the worst service? Why does the buses before the lunch break never show up? It’s one thing to be late but a whole different thing to just not show up. Ok correction it showed up 10 mins late.

  60. Your bus drivers are the worst!! I’m not from around the area and am completely reliant on your public transportation service. They missed me at stop ID 57761 twice at 8:45 abs 9:00 am on Tuesday, December 22nd 2015. Do they not see a person with a red backpack waiting at the stop sign?!! This is ridiculous! And it is raining. Your bus drivers are a disservice to the community.

  61. Kareem and Nelson
    Two lying idiots get a job and buy a car if you dont like it.
    Stop telling fibs. Buses come, maybe late but they come and the do not pass up people AT THE ACTUAL BUS STOP…


  63. These comments don’t show up on the desktop version of this site. A lot of people think this a form for private feedback. Its kind of funny to read all these rants. I think I know some of these riders.

  64. The DB that runs at 7:42 is always late. The bus driver drives really slow with no urgency or mindfulness of the schedule. This is the 3rd time I will be late to work due to this bus driver. I will have to start taking an earlier bus. If I get fired due to being late 3 times in a row this week 1/5, 1/6 and 1/7 – I will be very upset.

  65. There seems to be an ongoing issue with the 2:28 and 2:50 busses not showing up for their scheduled stops at Alvarado-Niles – Stop ID 55877. This happens several times a week while at least one “Sorry Out of Service” DB bus goes by. Today I have waited from 2pm to 3pm and neither of the busses arrived. Has there been a scheduling change? Why is this happening so frequently, as an only method of transit that goes from Alvarado Niles to Palo Alto Transit center, it’s unfortunate enough that it doesn’t run weekends, but when it’s not even reliable on weekdays, it’s simply frustrating and unacceptable.

  66. No bus showed up at 9:42 this morning, leaving everyone stranded at the Union City BART. Next bus due at 10:52 am, finally arrived at 11. Not the first time, and not acceptable. Having an entire bus just not run is ridiculous.

  67. Irina, learn the public transit system. Dont tell lies either. You were NOT THERE… The 2 scheduled buses both drive past these stops between 2:30 and 2:50. Why do people lie? Also, just an fyi. A bus that says “Out of service” is not a broke down bus, it means it doesnt pick up people until it gets over the bridge.
    So, everyday between 2:26 & 3:00 2 buses drive by there. Try being at the stop and you will get a ride maybe? Download an ap called NextBus and you will be proven wrong, every day…HA!

  68. One time, one frickin time is all is im asking for your bus to be on time. Why even have a schedule. Just tell riders to stand at the nearest station with a finger up their butt and wait till the next one comes. Its literally a fuckin joke. Been waiting since 4:02 for the 4:22 bus and 45 mins later 6 buses pass but not the DB.

  69. Why does the DB1 5 o’clock service don’t wait in the line to get on the ramp on Oregon Express like everyone else instead ride in the only Lan to get on 101 S. The bus seems to always jump in front of me. I wait in the long line. Yet this big bus rides on the side and jumps in front of everyone ….what the heck!
    I’m going to report this to the police. It’s not right and needs to stop.

  70. Anonymous must be a disgruntled bus driver chiming in since they seem to know everything about every bus stop, way to be a coward, maybe if you spent less time on message boards and more time Doing your job people wouldn’t be left behind at stops and busses would come as scheduled. Do your job or get a new one!
