Road numbers: 712969, 712971, 712986, 712995

An autorack, also known as an auto carrier is a specialized piece of railroad rolling stock used to transport automobiles and light trucks. Autoracks are used to transport new vehicles from factories to automotive distributors, and to transport passengers' vehicles in car shuttles and motorail services, such as Amtrak's Auto Train route.

In 2004, Canadian National was at the forefront of autorack technology again by using lightweight aluminum. The new cars, built by Johnstown America Corporation beginning in December 2004, are brand named AVC, an acronym for Aluminum Vehicle Carrier. Two hundred new aluminum autoracks promise a softer ride, a wider interior, superior door-edge protection, and a rust-free interior from older steel versions. Canadian Pacific Railway has ordered 375 of these new cars as well.

The new cars built for Amtrak Auto Train service differ from those built for CN and CP; the Amtrak cars are 3 inches lower, or 19' 11" , in height and use solid side panels instead of the perforated panels operated in freight service.
