Not getting response on B&M/MC thread so will try here. This past Sunday happened upon Johnsonville, NY tower and while walking the dog opposite the tower found concrete foundation that looked like it was a turntable pit. Was there, in fact, a table there or just a big water tower. Also wasn't this at one time a three way junction of the Troy line and the M'cvle line and the origonal Greenwich and Johnsonville? So speaking of G&J what and where do they operate today?n
