New York City’s subway system—far and away the most extensive in the nation—is not exactly a model for transportation infrastructure. The city has yet to open an extension line it started planning in the 1920s. Almost all of the existing stations have structural defects. Oh, and it’s still using a signaling system that was last considered high-tech 85 years ago.
At Manhattan's West 4th Street station, trains are controlled by a 1930s interlocking machine operated by physical levers that employees have to manipulate in order to reroute tracks and send out signals. Standing on the platform waiting for your ride home, you’d never guess that every time a train enters a station, there’s an actual human standing in a back room pulling on levers. See behind-the-scenes in this video from the city’s transit authority:
The New York City subway is basically a living museum. Which is awesome, except when you need to rely on it to get you somewhere on time. Railroad companies don’t even make the parts for some of these systems anymore, so the MTA has to make its own. On a slightly brighter note, the city recently approved a plan to shell out $205.8 million to upgrade its signal system along one of its busiest subway lines, allowing the transit system to run more trains per hour. Of course, that still leaves all the other lines hanging out in the early 20th century.

At least they aren't worried about their computer crashing.:hehe:

In reality I suppose the system is a computer in the strictest (and most primitive) sense.

Last time I rode the NYC Subway System was in the early 70's. Rolling stock didn't look much newer.

This is quite interesting and hopefully a portion of the system will be preserved somewhere at a transit museum and really is historically and technologically significant. When you think about it, the new system with its computers and transponders is more like a model railroad DCC system such as Linz or maybe more like the old Hornby Zero-1, while the old system is more like the Atlas manual block system with the cab-control.

Boston recently has upgraded its Green line trolley signaling to a more modern system from one that was of the same vintage shown in the video.

Our metro has been running the Westinghouse system for over 30 years, they're upgrading the whole network to CBTC now. It's got nothing on NYC though.
