The two railroads began similar southbound services last summer, which have enjoyed success.
UP shipments from Mexico -- with emphasis on Mexico City -- and Laredo will move to the railway's Marion, Ark., intermodal facility. NS delivery points are Atlanta, Charlotte, Jacksonville, Miami, Harrisburg, Pa., and E-Rail, N.J. (near Elizabeth).
Three services are being offered:
Trans-border, all-rail, seamless. It bypasses customs at the border by clearing within the Mexican interior. The handoff is to Transportacion Ferroviaria Mexicana (TFM) at Laredo.
Passport is combination truck-rail. Mexican shipments move by truck to Laredo and are forwarded to U.S. destinations.
Conventional service allows arrangements for local pick-up in Mexico for movement to UP's Laredo facility.
Northbound traffic is expected to be mixed freight.
