New York’s Paleolithic Subway Signalling

Second Avenue Sagas pointed me at this new video about the signal replacement project on the New York subway system. The first couple minutes show the fossilized remains the original signaling system that is, amazingly, still for the most part used to control the subways. If the video doesn’t display for you, click here.

The MTA has a program underway to replace these, but it’s proceeding at snail’s pace. Only the Canarsie Line/L-train is complete, and the Flushing Line/7-train will be finished in 2017, supposedly. It will take five and a half years just to upgrade the western segment of the Queens Blvd Line. At this rate I’ll be long dead before they finish upgrading the whole system. And by that time, the new “state of the art” CBTC signalling system will itself long be past end of life.

It’s very difficult to upgrade NYC’s subways because they are a 24 x 7 x 365 system. The MTA employees do a fantastic job of keeping it going in difficult circumstances. But given the MTAs dubious record on major capital projects in terms of cost and timeline, it’s hard to believe this is the best that can be done.

This also shows why fully funding the MTA capital plan is so important. It’s about dealing with critical upgrades to the existing system to keep things going. If anything, the amount of capital funds devoted to the CBTC signal program should be significantly increased to start upgrading multiple lines in parallel.
