Posted by Wado MP73 on Fri Jan 27 23:30:47 2012, in response to Re: Latest updates: R-179 order saga, R-160 CBTC for (L) line & special reports ..., posted by J trainloco on Fri Jan 27 22:40:23 2012. The induction loop on line 14 can be used for both one-way ground-to-train and two-way communication. I believe it uses different frequencies for send and receive data. When an older stock runs on the line, it uses traditional fixed blocks. The MP89CA will use what they call "virtual blocks", which are much shorter software based blocks rather than physical track circuit blocks. They are still not moving blocks though. If an MP89CA loses contact with the PCC (Command Center), it will be treated as older stock and falls back to one-way communication and traditional fixed blocks.As for automation of other lines, the logical move is to automate line 4 or 13 next but I think it's still up in the air. It's up to the success of line 1. The relay at line 13's southern terminus is already automated. Trains leave the arriving platform, relay and come back to the departing platform by themselves. I still can't get over how Siemens used the L as a guinea pig and left NYCT with a proprietary, semi-finished product so they can sell a finished product to RATP. |
