The statewide simplex is 450.050.
The Antennae to which you refer are for the MetroNet Train Radio
system, and they operate in the 418-419 MHz range. They carry data
and voice. Some of the data transmissions are:
Transponder pass information
Train and stock Numbers
I'm sure there's plenty of other stuff.
Russell Bryant's RailScan CDs have a lot more information if you're
interested - email@example.com
