Union Pacific Railroad recently introduced a new intermodal service offering between Chicago and Monterrey, Mexico, giving companies another option to move goods across the border six days a week.

Trains carrying intermodal containers will interchange at Eagle Pass, Texas, to and from Ferromex, Mexico's largest railroad, which will operate trains between the border and Monterrey.

Union Pacific and Ferromex have reportedly made significant terminal, track and equipment investments for this new service.

Intermodal shipping incorporates multiple modes of transportation, in this case, truck and rail, to capitalize on the advantages of each mode. This form of transportation allows consumer and manufactured goods, such as clothing and appliances, to be transported across the border in a cost-effective and timely way..

Union Pacific is the only railroad serving all six Mexico gateways: Laredo, Eagle Pass, El Paso and Brownsville in Texas; Calexico, Calif.; and Nogales, Ariz, according to the company.
