JAzumah Posted February 12, 2021 Share #1 Posted February 12, 2021 How different is the door positioning on the R62/62A cars versus the R142/142A/188 cars? With a service life of 5-7 years remaining on the R62/62A units, it could be feasible to retire them 1-2 years early in order to install platform doors on the entire A Division. The latest report about excessive amounts of PM2.5 particulate matter in the system's air seems to suggest that if platform doors can be installed, a dual filtration/climate control system can be introduced to the subway system. It is theoretically feasible for NYCT to go to a single car type in the A Division to accomplish this goal. 0 Quote Link to comment Share on other sites More sharing options...
Kamen Rider Posted February 12, 2021 Share #2 Posted February 12, 2021 Doing that is completely and totally dependent on the R262s coming in and not being a total disaster... 0 Quote Link to comment Share on other sites More sharing options...

It is theoretically feasible for NYCT to go to a single car type in the A Division to accomplish this goal. Assuming we have funding for R262s, which looks doubtful at this time. Not to mention that the R62/62A cars are running very well, unlike the R46s. The R62/62A cars have parallel side doors, where the doorways on both sides line up with each other completely. The R142/142A/188 cars have parallel side doors only in the A (cab) cars and staggered side doors in the B (non-cab) cars, an arrangement that was carried over from the R110A test train in the 1990s. Also, the R142/142A/188 cars have wider doors than the older cars do. The easiest thing to do would be for the R262s to retain the door arrangement from the R142/142A/188s as well as retain the same door width. Then you’d install the platform doors. This way, they wouldn’t have to retire the R142/142A/188s early. But once you install platform doors you are locked into that same specific design for eternity, including on the line whose only track connection to the rest of the system is to the at Queensboro Plaza. It’s possible that platform doors would also lock the into its current 561-foot, 11-car train limit. I don’t think Queensboro can fit a 12-car train of A-Division cars. I’ll be honest, I always wanted Transit to revisit the possibility of 60-foot, narrow width cars for the for 600-foot long trains to cope with the crowds on that line, but even an order of 400 such cars (which is more than some systems’ entire fleets) would probably be impractical, because they would be restricted to the line. They’d be too narrow to operate on any of the lettered lines, that’s for sure. Edited February 12, 2021 by T to Dyre Avenue 0 Quote Link to comment Share on other sites More sharing options...

Worst case scenario, you can use wider platform doors to account for variable positions. It would be good to see the two cars overlaid on top of each other to determine exactly where the doors line up. 0 Quote Link to comment Share on other sites More sharing options...
bobtehpanda Posted February 13, 2021 Share #5 Posted February 13, 2021 We gonna install doors with what money? The MTA already needs to spend billions on ADA upgrades. I'm a bit doubtful about how realistic it would be to actually introduce climate control. Modern HVAC needs a lot of ductwork, and it's not like the stations have very high ceilings or spare wall space for duct work to go in. 2 Quote Link to comment Share on other sites More sharing options...
