Re: Tuscarora Almanac for October 10

Correct, and Joe Brennan's amazing diagram reminds me to be more specific about Grand Army Plaza. Entering the station going south, the IRT local tracks are on the upper level across the wide island platform. Deeper under that platform are the two BMT tracks, descending, and deeper still under the IRT local tracks are the IRT express tracks, rising.

About one-third through the station the descending BMT tracks go deeper than the rising IRT express tracks, so leaving the station the IRT local tracks are on the upper level heading east with the IRT express tracks under them, and deepest are the BMT tracks still heading south deep under Flatbush Av.

It's an astonishing example of design and engineering, yet they then got the Rogers Junction so terribly wrong.
