I absolutely see no reason for thatThere's a reason. It's utterly inefficient to have duplicate electrification; it's just not done. You've got the cost of three railroads overlaid onto one. MBTA isn't even considering getting electric equipment . . . and MBTA has what to do with this? Like I said, This is an Amtrak project AIUT, it's a NYS project. Amtrak has nothing to do with it at all other than being the operator. Good luck feeding high voltage AC on DC only equipment It's not as expensive to put rectifiers on M7s as keeping multi-voltage equipment such as the M2/4/6/8, never mind having several transformers and rectifiers at ten times the number of substations as you'd have with AC overhead. And besides, since when are M7s "DC-only"? They do have AC traction motors, albeit with the IGBT inverters. There are quite a few HSR lines that were newly built and started off with that level of frequency Apples/oranges comparison. Block length, remember? Average speed is doubled there versus what's intended for NYP-ALB, a regional-type operation. |
