Bellmouths and tunnel expansions |

Posted by G1Ravage on Wed Oct 17 02:42:24 2007 Now that I've had a chance to explore the B Division up close a bit more, I've spotted some things I want explanations for.-Track T2 of the 63rd Street Tunnel (F) line, between 21 Street - Queensbridge and 36 Street. Heading northbound from 21 Street, the tracks suddenly curve sharply to the left. Looking out the window to the right, it appears as though the tunnel was built for the track to continue straight for a considerable distance. Was the 63rd Street Tunnel originally supposed to go elsewhere, rather than just connect to the Queens Boulevard Line? -The 4 Avenue Line in Brooklyn, between 59 Street and Bay Ridge Avenue. Was the tunnel there originally built to support a 4-track line? After the Sea Beach tracks go down south of 59 Street, the 4 Avenue tracks sharply come in on themselves, as if taking the place of "express" tracks. In the tunnel approaching Bay Ridge Avenue, there's a place where you can briefly see out of the tunnel to the outside. Though under the street, you're actually on a bridge going over some freight tracks (the same tracks that run alongside the (N) at 8 Avenue). While looking out through this opening, you can see that right next to you looks to be the support structure for a "local" track on either side. -Track G1 (lol), just north of Fifth Avenue - 59 Street. Not a tunnel, but a walkway or hallway of some sort, going away perpendicular from the tracks toward some back area. Looks pretty long, and it's gated off. What's back there? I may think of more later. |
