rider1 Posted November 15, 2008 Report Share Posted November 15, 2008 Would you guys know why some transits run their buses in 2nd (or 3'd depending..)as opposed to drive or OD? I know Kingston has used this practice ever since the 78-79 fishbowls and the GM classics Wouldn't bringing in the OD gear, save a ton of fuel .especially over 60kmh. thanks , ROb Link to comment Share on other sites More sharing options...

Those V series, particularly the V730 model will causes whipplash back and forth once kicking into 3rd gear. The V731 does it from time to time. It's not they are running over 60 clicks on the road on most times, most operators and passengers wants better comfort when vehicle is in motion without feeling any roughness.

BCT-3122-D800-10240 Posted November 16, 2008 Report Share Posted November 16, 2008 When driving our Fishbowls or Classics here in Calgary with V730, V731, VR731 transmissions, I run them with the gear selector in 2 unless I am going to go more than 60 KM's an hour. As 'General682002' mentioned, sometimes those transmissions tend to shift up and down at around 60 KM's causing a rough ride from the transmission 'jumping'.

Wonka Posted November 16, 2008 Report Share Posted November 16, 2008 I noticed that a lot of buses get ran in 2nd gear in the winter, I'm guessing to combat wheelslip. Link to comment Share on other sites More sharing options...
general682002 Posted November 16, 2008 Report Share Posted November 16, 2008 I noticed that a lot of buses get ran in 2nd gear in the winter, I'm guessing to combat wheelslip. Which bus? There's are several buses that have from 3 to 6 speed. I do remember riding on West 5th hill, some drivers downgear from 5 to 2 on uphill to lockup the gear, the same goes on downhill.

Cogeno Posted November 23, 2008 Report Share Posted November 23, 2008 Hmm... maybe that's what was happening on that fishbowl I rode? If you look at my vid of STO 8202, it sounds like it tries to go into third, but doesn't :S Link to comment Share on other sites More sharing options...

M.Wright Posted November 23, 2008 Report Share Posted November 23, 2008 How fast is the driver driving? Was he on the Autoroute?I think this is the video in question:http://ca.youtube.com/watch?v=Vu5sY81FdJE It looks like from about 2:40-3:30 is the best example of what Cogeno is talking about. Looks like at 5:30 it tries to shift to 3rd but shifts back to 2nd too. Link to comment Share on other sites More sharing options...

Either driver downgear or the 3rd gear takes longer to reach. Those V730 transmission usually takes longer as it reaches the RPM out from 2nd gear, around just over 60 clicks.

KTeen Posted April 25, 2011 Report Share Posted April 25, 2011 I know Kingston's 8790 (a GM Classic)'s transmission was messed up, it would only drive in 2nd gear. It was recently retired and is still used as a training bus, but is occasionally dispatched during bus shortages despite its missing farebox.

nbbusdriver Posted April 26, 2011 Report Share Posted April 26, 2011 I use second gear when driving our Classic 737. If you leave it in drive, it doesn't have the pick up or RPM's to run efficiently. Works for me Link to comment Share on other sites More sharing options...
OC Transpo 8238 Posted April 26, 2011 Report Share Posted April 26, 2011 I know an STO operator when driving a Classic he will have it in 2nd until he gets back into Quebec if going over Portage because it's such stop and go on Rideau/Wellington.

Teddy Posted April 26, 2011 Report Share Posted April 26, 2011 One of the Kingston Transit drivers always, always drives the bus in 2nd. I'm sure on these older buses it made a difference but on the D40LF/LFR it doesn't seem to have any benefit. The engine gets really loud when he gets up to speed.
