Eastman346 Posted July 27, 2011 Share #1 Posted July 27, 2011 I've been recently noticing very violent bucking on the route R46 cars. One was so violent that riders had nervous looks on their faces. In the more than 20 years of riding the subway I've never seen cars buck like this before. Riders were almos being thrown around cars and school girls screaming at the loud booming sound and vibrations of the bucking. It felt like a unusually long delay in the release in the braks. I started getting a little nervous myself. :eek: Link to comment Share on other sites More sharing options...

LRG Posted July 27, 2011 Share #3 Posted July 27, 2011 When the dynamic brakes don't kick in, the cars buck. A red light comes on in the cab when the T/O is braking and it comes on when there are no dynamics. Link to comment Share on other sites More sharing options...

Joe Posted July 27, 2011 Share #5 Posted July 27, 2011 In the good ol' days, it'd go something like this: Fuse blown. Car won't go into parallel. Motorman replaces fuse; wraps up controller. Fuse blows again. Ah, ****, ok, that car won't go into parallel. Keep going. Eventually, car goes into shop. Maintainer replaces the fuse, sends the car right back out, making sure not to put it in parallel while it's moved. Motorman gets on train in terminal, notches up into parallel. Fuse blows. Ah, ****, HERE WE GO AGAIN! Link to comment Share on other sites More sharing options...

traildriver Posted July 27, 2011 Share #8 Posted July 27, 2011 It's like taking your car to the mechanic for factory warrantee service. The mechanic will invariably write on the work order" "Could not duplicate problem", and tell you there is nothing wrong...... Link to comment Share on other sites More sharing options...
2 Train Master Posted July 27, 2011 Share #9 Posted July 27, 2011 You want extreme bucking ride the B cars on the R-46's. Ride the R-32's and the 142A's on the . Link to comment Share on other sites More sharing options...
cdi919 Posted July 29, 2011 Share #10 Posted July 29, 2011 When the dynamic brakes don't kick in, the cars buck. A red light comes on in the cab when the T/O is braking and it comes on when there are no dynamics. what the hell are you talking about? that red light comes on when the friction brake is being applied. the train bucks when you take power and the brakes have not fully released.

Sorry Mr LRG that is the AIR BRAKES light and the other one is for HANDBRAKES Link to comment Share on other sites More sharing options...
cdi919 Posted August 1, 2011 Share #14 Posted August 1, 2011 Would it also buck if you had a few dead motors scattered in the consist? not really. a dead motor will roll and most of the time you wont know you have a dead motor. unless you see you are not getting enough propulsion ie the train maxes out at 25mph. or when you dont have any dynamic braking and its a long hard friction brake into the station.

TwoTimer Posted August 1, 2011 Share #15 Posted August 1, 2011 Would it also buck if you had a few dead motors scattered in the consist? Another idea comes from trains that hold too much in their mini brake position combined with strong motors (min brake can hold anywhere from 10-30 lbs depending on the particular consist). Its one of the most important things learning about when trying to operate a R46 (What exactly is the min brake going to give me on this train?).

Boomerang503 Posted August 2, 2011 Share #16 Posted August 2, 2011 Maybe it's just me, but all of the Redbirds that I rode in had hard starts. I had to brace myself at every station, and for me, that was on the from Fulton to 233rd and back. Link to comment Share on other sites More sharing options...
R68 Subway Car Posted August 3, 2011 Share #17 Posted August 3, 2011 They gotta fix that problem. As far as I know, the (A)'s R46s do not have this issue. Link to comment Share on other sites More sharing options...
Grand Concourse Posted August 3, 2011 Share #18 Posted August 3, 2011 Isn't it because one of the B-cars in a set was equipped with a motor? Link to comment Share on other sites More sharing options...
