A track and interlocking diagram for "Massachusetts Ave" tower and interlocking machine information...

Matthew Lappin: question, was the diamond a slip switch or moveable point frog setup.

believe the NKP Hole track was for a PSI substation

Daniel Kopack: That would be a slip switch..

Daniel Kopack: Indy had one of the best track plans of any major city...
