MoPac Operations

[nanaimo73]

I have a 1963 map showing the old line being used, and the Southern Pacific line still being used by SP. The Terraserver 1975 map shows MP using the SP line and the SP abandoned to the south. I would guess SP andoned their line in the 1960s and MP switched at that time.

Secondly:How Did The MP/NdeM Handle Passenger Operations With The "Aztec Eagle"In Laredo,Texas/Nuevo Laredo,Mexico?? Your Answers Are Greatfully Appreciated.[:D]
