Posted by Stephen Bauman on Wed Feb 10 12:29:10 2016, in response to Re: Canarsie Line During (L) Tunnel Shutdown/Atlantic Avenue (L) station, posted by #5 - Dyre Ave on Wed Feb 10 11:23:30 2016. Perhaps my explanation wasn't clear.CBTC-equipped trains can run anywhere without affecting other trains on any line. Non-CBTC trains can run anywhere. However, if non-CBTC trains are anywhere on the Canarsie Line, the signal system will revert to the AWS mode. This mode can handle only 3 tph. There will be spare R143s available when the tubes are shut down. How many? The following is left as an exercise for the reader. There are 212 R143's and 32 R160's that are CBTC equipped. 24 trainsets, comprising 192 cars are required for peak am operation. The rest are spares, some of which might be undergoing maintenance. The running time from Canarsie to 8th Ave is 38:30. The running time from Canarsie to Bway-Jct is 10:00. The running time from Bway-Jct to Myrtle-Wyckoff is 6:30. The running time from Myrtle-Wyckoff to Bedford is 13:00. |
