Re: W 4th Street

As the video in the link provided shows, B3 track begins an upgrade at a point where the Emergency Alarm (EA) Blue Light is located immediate south B-way Lafayette. Too late for a cross-over from tracks B1 to B3.

The IND tunnel is pretty deep under Houston Street since it must pass under two mezzanines at B-way Lafayette where the lower IND mezzanine is under the IRT Lex, and BMT Broadway subway tunnels.

A cross-over north of B-way Lafayette from Track B1 to B3 would require additional support to horizontal steel beams as vertical columns would need to be removed to make open space for a single cross-over. Any such crossover would have to take place north of the express track B3 to B4 cross-over located north of the station.

Unfortunately the tunnel ceiling north of the B3-B4 cross-over is not sufficiently high enough for civil construction work to under pin horizontal beams that presently hold up horizontal steel work found in curtain walls.

South of the B3-B4 cross-over the tunnel ceiling rises because of the deep cut, however also at this point B1 track moves away to the right of B3 to create a rather long tapered open void space as tracks approaches the Express station platform.

Unfortunately there is too much civil construction work that must take place to install any cross-over switch from B1 to B3. Anything can be accomplished with public money, if available.
