That includes overhead. There were several projects planned with the funds just passed. See to remember all were in SEPTA service area. Power for the west CAT past the At Glenn 169Kv transmission line is about at present service. That may be reason some Keystones end up with diesels if there are power problems? Cannot remember for sure but the high voltage to the power station transformer was only 3 - 4 times that of the original CAT power of 11Kv. That would make it as I remember it was 44Kv high voltage???IIRC, that is the oldest CAT on the system, some is over 100 years old now.
If that is still true, then Acelas to HAR will need improvements to CAT and available power delivered.
