Posted by gbs on Sat Nov 7 02:13:04 2009, in response to Re: Some questions about the L, posted by TheCanarsieConnection on Fri Nov 6 22:39:24 2009. There was a time (early '90s?) when the Canarsie-line underwater tunnels were considered unsafe because of lack of fire-extinguishing capabilities, and two trains could not be in the tubes at the same time, so, for example, a Manhattan-bound train had to wait at Bedford Avenue until its leader arrived at First Avenue.The tubes were upgraded, fire pipes installed, new signals installed, and suddenly the trains were flying through at 50+ mph, way before CBTC and R143s. Alas, the poor #7 riders, stuck with tubes that have 20 mph speed limits. Most other under-river tubes have standard 35 mph speeds. |
