GM's ''
Aerotrain'', in service as the ''City of Las Vegas'', makes a station stop on its way to
Los Angeles in 1957.
The '''City of Las Vegas''' was a
named passenger train operated by the
Union Pacific Railroad between
Las Vegas, Nevada and
Los Angeles, California in 1956. Train Nos. 115 and 116 initially utilized
General Motors' experimental ''
Aerotrain'' unitized trainset, but the Union Pacific terminated their lease within a year due to maintenance and performance issues. Service on the line continued with standard streamlined equipment painted in UP's ''Armour Yellow'' livery.
In the early 1960s the name was changed to the ''Las Vegas Holiday Special'', when both the consist and schedule were reduced. Service was discontinued altogether in 1967.
