The Robert Pearson Collection: Universal Air Tramaire Air Locomotives

Universal Air Tramaire in Wallace ID, I took these photos during the summer of 2002

 

The material shown below is from the collection of Tim Stolle and used with permission.

Tim notes that Tramaires have a complex history but were eventually manufactured by the Universal Tramaire Company out of Denver, CO.  Although they are similar to Eimco machines, there are some differences between them.  The Eimco has a
two-speed transmission that provides a high and low range of gearing while the Tramaire is a simpler machine with forward and reverse but only one gearing range.  As far as Tim could tell, Eimco only produced  the 401 model but as shown in the brochure below, Tramaire developed a line of compressed air locomotives that were built for a range of service options and needs.
