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 . talmeisa ogans says january 31 2013 at 4 05 pm 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 becki says february 1 2013 at 4 41 pm db

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 . stephanie linne says june 11 2013 at 6 04 pm i arrived at the bart station stop on tuesday june 11th at 5 18pm . although i was almost 5 minutes early the dumbarton

much . laura tibbs says june 19 2013 at 3 51 pm 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 . pia says july 16 2013 at 1 11 pm 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 . lily says july 17 2013 at 11 01 am 7 17 13 the db bus which departured at 0942 from union city towards stanford oval was widely early

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 . ivory carver says october 8 2013 at 6 49 am 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 . mike lee says october 29 2013 at 8 29 am 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 can not run it with minimal professionalism get out of this business and leave it to someone who can . mike lee andrew m. says december 24 2013 at 6 19 am 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 brian says january 9 2014 at 10 27 am is there a monthly pass available for this line
