==Alaska Railroad: Service through a long one-lane tunnel==
An Auto Train type of service utilizing autoracks and [[passenger car (rail)|passenger cars]] was operated in Alaska at the [[Anton Anderson Memorial Tunnel]] through [[Maynard Mountain]] near [[Whittier, Alaska]], which is part of the [[Portage Glacier Highway]].
Completed in 1943, with a length of 13,300 feet (4054 [[m]]), it is the longest [[highway]] [[tunnel]] and longest combined rail and highway tunnel in [[North America]].

In the mid-1960s, the [[Alaska Railroad]] began offering a shuttle service through the tunnel which allowed vehicles to drive onto auto carrier cars to be transported between Whittier and the former town of Portage. As traffic to Whittier increased, the shuttle became insufficient, leading to a project to convert the existing railroad tunnel into a one-lane, combination highway and railway tunnel which was opened to traffic on [[June 7]], [[2000]].
