will there ever be an update to the peninsula corridor line to include updated stations, the new EMU's and Overhead lines? and extensions to Gilroy and such?
If so, the route needs a UP GP60, GP40N/GP40-2, SD59MX, and/or SD70M for more freight variety, as well as the new EMUs.
There's no plans to do that. Extension to gilroy would be kind of pointless because very few trains stop there. I think tamien is the best stop location.
