Posted by J trainloco on Fri Apr 20 18:03:11 2012, in response to Re: Rush hour J to 9 Av, posted by Joe V on Fri Apr 20 17:14:22 2012. I pulled up the July 2009 car assignment, which have the V and W still running, and compared it to current fleet assignments. Here's the result:The C, J/Z, L, and M (to Bay parkway) required 18, 19, 24 and 17 trains, bringing the total number of 480' trainsets required to 78, or 624 cars. Presently, there are 222 R32s, 50 R42s, 372 R160s and 212 R143s that can be utilized to make 480' sets. That's 856 total cars. That's roughly a 27% spare factor there, which is a lot more than you need (although the R32 is higher than that nowadays). Throwing out the franklin shuttle, the rest of the B division needed the following number of trainsets: A-38 B-25 D-30 E-26 F-45 G-6.5* N-23 Q-18 R-29 V-15 W-10 Rock pk-1.5* The grand total number of trains needed: 267. Presently, the rest of the B division has 752 R46s, 416 R68s, 200 R68As and 1,290 R160s available for 600' long trains (or 300' long trains). That's 300 trains. And while that means there's an 11% spare ratio for the 600' long consists, (far too low), the spare ratio for the whole fleet is just above 15%, which is only a little bit more ambitious than what the MTA would like to achieve. The issues that led to the decision to scrap the R44s meant that they were on the way out, regardless of whether or not the M/V combo happened. |
