KK 6 Ave Local Posted May 12, 2018 Share #4182 Posted May 12, 2018 (edited) Since Wikipedia only updates on actual confirmations, I think I might have some proof of R160s and R32s going to the https://en.wikipedia.org/wiki/G_(New_York_City_Subway_service) It states: Despite the influx of ridership, train lengths did not change. However, in 2016, it was announced that the G is expected to get full length trains to accommodate displaced L train riders in 2019. This is made possible because the delivery of new R179 subway cars consists to other routes makes it possible for older fleet from these other routes to be passed onto the G.[45] In addition, three extra G trains per hour would run during peak periods, for a total of 11 trains per hour during the shutdown. A full-length G train would run every five to six minutes, nearly tripling the route's capacity from eight to twenty-two 300-foot consists per hour. Since the G train's schedule is designed around that of the F train, train frequencies on both routes would have to be modified.[56] Edited May 12, 2018 by KK 6 Ave Local 1 Quote Link to comment Share on other sites More sharing options...

Yes, they will be there for a little while before they get moved again (or such is the plan as of current). 0 Quote Link to comment Share on other sites More sharing options...

Closer, but not entirely true- Mileage of individual cars is directly related to both span of service, and consistency of service. Having a high peak frequency but low off peak frequency results in lots of trains sitting around for much of the day getting little use. Having a line with consistent service, regardless of whether it is short and infrequent, or long and frequent, results in trains with high mileage. Short vs long, and frequent vs infrequent both affect the number of trains you need, but not so much the overall usage of those trains. 1 Quote Link to comment Share on other sites More sharing options...

Short vs long, and frequent vs infrequent both affect the number of trains you need, but not so much the overall usage of those trains. I’d go even a step further and say that really what matters is the disparity between peak and off peak service. Aside from short lines where time in terminal makes up a non-negligible portion of total run length, whether a route is short or long is frankly irrelevant provided trains are moving at similar speeds. For example, I could make 3 trips on a 40 minute length line in the same time as one trip on a 2 hour line, and if we’re both moving at say, 20 miles per hour average, we’ll end up with approximately the same mileage, thus rendering route length irrelevant, and the number of cars getting down time in the off peak much more so. That said, these issues of car age/mileage are really not too important. The issues that car equipment/OP look at when assigning fleets really have to do with passenger flow. As has been said before, the number of delays attributable to car malfunction is statistically irrelevant when compared to other categories — for example overcrowding/insufficient capacity. Especially on lines like the Lex, where station dwell is the limiter on service, planners will be looking to assign the fleet that’ll best facilitate passenger movement given the line’s ridership characteristics, fleet reliability be damned. Consequently, the stats that’ll end up being really important are doors per train, door width, door positioning, seating capacity and standing capacity. 7 Quote Link to comment Share on other sites More sharing options...

Consequently, the stats that’ll end up being really important are doors per train, door width, door positioning, seating capacity and standing capacity. This is very accurate. As I mentioned before, the marginal delay impact of MDBF differences between fleets is very small, and only becomes worth considering when the relative difference between the MDBF of two fleets is over ~150K. Besides the ability to handle crowds, there are some other factors, like electronic vs. non-electronic signage and shop familiarity with car classes that go into the decision-making process. However, the main goal is usually to maximize throughput, with all other factors being secondary, subject to cost considerations. A good example was the decision to place the R62As on the 6, rather than the 4, in order to not "contaminate" the entire Lex express service with the empirically-demonstrated increased dwell times of the R62A fleet in areas of high station crowding. I'm sure that this has been repeated before, but the term "overcrowding/insufficient capacity", while used as a delay "cause", is more accurately a definition of a symptom of a delay. Many operational factors, including the relative impacts of car assignments, can have an impact on this "bucket" of delays. I'm sure you (RR503) know that, but I think it deserves explicit clarification for others. To put it simply, overcrowding is often a symptom of other operational issues, rather than a discrete cause of delay. 14 Quote Link to comment Share on other sites More sharing options...

No confirmation needed, they’re physically in service based on the conditions that the viaduct project is Complete. I wouldn't automatically assume that all 24 were just placed back on J and Z. They needed a thorough inspection after returning to ENY from isolation, so it appears there were no unusual circumstances. That's good news, for the time being...hardy beasts, indeed.
