Then they realized full length is not really needed because riders prefer to the instead. You realize full length is just simply postponed, not discontinued. 0 Quote Link to comment Share on other sites More sharing options...

I feel that r32 and r46 is faster than the r179 (A). The pre NTT cars don't have air bag suspension, and the sound proofing isn't as good, so they feel faster than they are. I know for sure the 179s are faster on the flats than the 32s & 46s, as I tracked the speed on all three fleets on my GPS app. If the SMEE's still had their field shunting, they probably could hold their own speed wise against the tech trains. I think the Staten Island R44's still have field shunting and those accelerate far faster than any of the SMEE's in the current fleet and probably have the same acceleration rates, if not better than the NTT. 2 Quote Link to comment Share on other sites More sharing options...
RR503 Posted May 11, 2019 Share #4630 Posted May 11, 2019 The NTTs and SMEEs should theoretically all accelerate at the same rate. They all are designed to meet the same tractive effort curve because they all interact with the same signal system. Differences in performance between the fleets (which, mind you, are extant) stem from the type of traction control used on each. NTTs use AC, which essentially allows cars to provide exactly as much tractive effort as the accel curve specifies, whereas the rheostatic DC control systems used on older cars allow less precision control and, through their post-1995 modifications, are prone to lowballing tractive effort. 4 Quote Link to comment Share on other sites More sharing options...

Dan05979, one of the transit employees who posts on the forums from time to time, explained that a little while ago in this thread, particularly. However, the problem I have with the is that on their 2017 Subway Action Plan, they stated that the will become full-length, particularly for the shutdown. And then comes along Andrew Cuomo, who had the nerve to step in last minute to see if the original proposed full-time 15 month shutdown was worthwhile. Pissed me off too, since that was a pretty slick and snide move in an attempt to make himself look good. In general though, if the didn’t want the to be full-length, they could have just said so like they first did in their full review of the and lines released back in December 2015. Instead, the agency tends to lack common sense a lot most of the time and constantly changing their minds every now and then. The current R179 issues plus the cancellation of the L shutdown is the reason why the isn't full length yet. Plus the R32's are being sms'ed at 207th st. They are playing it safe right now since there's another major flaw with the R179's as well. It's better to iron out all the issues first, then make decisions. 0 Quote Link to comment Share on other sites More sharing options...

And I heard that R179 8 car set cannot be converted to 10 car set. So the problem now is simply the TA does not have enough cars. The only way they can go now is to have R32 10 car set. 0 Quote Link to comment Share on other sites More sharing options...

There are enough 179s in service to make the full length at this point; they are having some issues, but not to the extent (I believe) that they cannot make service. 0 Quote Link to comment Share on other sites More sharing options...

The weld defects in the collision columns are not anything that impact the structural integrity or strength of the R179s, right? At least that's what I saw online about that latest problem 0 Quote Link to comment Share on other sites More sharing options...
VIP Posted May 13, 2019 Share #4638 Posted May 13, 2019 The wasn’t officially planned for full length trains because of the R179 surplus. With the origami plan, the was going to be assigned majority of R46’s while the would’ve been dominated by R32’s.

That = More ridership. The was planned to go 600 feet in 2010 with R46's but the R44 issues and retirement shelved that plan. So it's not because of the shutdown. MTA had this planned for years. 0 Quote Link to comment Share on other sites More sharing options...
RR503 Posted May 13, 2019 Share #4642 Posted May 13, 2019 In the most recent iteration of the full length plan, the was going full length for the shutdown. What exact fleets were going to be used for that operation is frankly immaterial to that question, as it was the movement of the shutdown to weekends -- and thus the fact that MTA couldn't charge the marginal cost of full length s to the capital budget -- that killed it, not some re-assortment of B division cars. 0 Quote Link to comment Share on other sites More sharing options...
Jemorie Posted May 13, 2019 Share #4643 Posted May 13, 2019 Had the R44s been kept while the R32s and R42s were thrown out the window at last, the would have easily been full length using R44s and R46s in 2009 or 2010. They were able to succeed in making it 100% full length 600 feet long in the Summers of both 2011 and 2012 with the infamous R32 / R46 swap, but not without eating into some cars from both Jamaica and East New York, respectively, shorting the spare car factors for both yards. Which is why two to three sets of R42s (30 cars total) also ran on the in addition to non-Pitkin assigned R46s from Jamaica because all current 222 R32s from 207th Street at the time were just not enough to cover half of the ’s fleet. In 2010, there were an extra 28 R32s but they have since scrapped them (the 8 cars stored at Fresh Pond in a shellnut) or now used them for work service. 0 Quote Link to comment Share on other sites More sharing options...

Lance Posted May 19, 2019 Share #4647 Posted May 19, 2019 Another thing of interest in the latest observations is the almost doubling of the MDBF for the 142As, previously one of the chronically under-performing cars in service. I'm still concerned that they are still performing at half of what the 142s can accomplish, but this increase is a good start. 1 Quote Link to comment Share on other sites More sharing options...

T to Dyre Avenue Posted May 20, 2019 Share #4649 Posted May 20, 2019 I wonder why Westchester didn’t treat the R142As well. Interestingly, the R62As have also shown a moderate increase in reliability (not as much as the R142As, but still it’s an increase). 0 Quote Link to comment Share on other sites More sharing options...

The personnel at certain yards don't preform a lasting job on their fleets. When it comes to the A Division, Jerome Yard is known for keeping their equipment clean and in optimal-working condition. Their R142s/R142A's are shiny clean and are taken seriously from a maintenance standpoint. 0 Quote Link to comment Share on other sites More sharing options...
