3000, must be the first run west of the SD40-2's!
@Kurt Moose- Deliveries of 3000 series units began about mid-1972. They had been west before this order was copied. I wonder a bit about putting the westward tonnage in an uphill siding. Starting up there might have been an interesting chore, especially in mid-winter. They could have waited at Beverly, or X5009E could have been met at Kittitas.
Yeah, that's a tough place to start a train! Sanders all the way to Boylston!
