Double-Stack Two containers stacked vertically on a train. Doubles the capacity but there are problems with clearances of bridges and tunnels. Double stacks must be transported on routes specifically designed to accommodate the higher vertically stacked containers. Specifically the recommended height by the AREA of obstructions along the route is 23 feet. (1995, Wegmann et al).

ILC Intermodal Logistics Center (a.k.a. Integrated Logistics Centers). ILCs are large facilities covering hundreds of acres that provides for the intermodal transfer of goods between modes that may include rail, trucking, air, and seaport in various combinations depending on location. ILC are best located near major highway corridors to make it easy to get the goods on and off the facility. In some cases other services are provided including fuel, driver services, hotel accommodations, food facilities, and security. Complimentary businesses are also collocated such as warehousing and distribution centers

Can handle any combination of trailer length and train sets can move as many as 40 trailers at a time. The system is currently employed by CSX Railroad in Chicago and Detroit. (1999, Volpe Center)

MTS Metropolitan Transportation System. The “Metropolitan Transportation System as defined in ISTEA has a multimodal focus, an integration focus and a functional focus. As such, it reaches beyond the old road categories to look at principal arterials in the metropolitan areas, transit corridors, intermodal facilities such as trucking distribution centers, passenger terminals, ports, airports and railheads, as well as rail rights of way. The focus is on the integration of all the modes in the way that the user integrates modes in a trip into a functioning metropolitan system”(Dittmar, 1994).
Multimodal Planning A process of collectively addressing all modes of transportation.

TEU Twenty-foot Equivalent Unit. Refers to capacity measurement of containerized freight. Because containers and trailers come in various sizes from 20 to 53 feet in length it is difficult to express the capacities of trains and ships. The TEU is used to convert capacities to a single known unit of a 20-foot container (20L x 8W x 8.5H). For example, a 40-foot trailer would equal 2 TEUs, a 50-foot trailer would equal 2.5 TEUs (1995, Wegmann et al).
