TTCI 203 at the Government's Pueblo Transportation Test Center on 19 April 2008 (Nathan D. Holmes photo)


Federal Railroad Administration, created in 1966, has several responsibilities none more important than safety of the traveling public, railroad employees and shippers. To that end, the government agency is constantly evaluating systems, inspecting equipment and testing new technology to advance rail safety. The Transportation Test Center in Pueblo, Colorado is the agency's primary field testing site. Follow this link to read more about the TTC Locomotive Test Fleet.

Back in 2018, Michael Richmond and I assembled photos for a mini-profile on Union Pacific's Double Diesels, much like other "Remember When?" profiles that had previously appeared here. Long before we could pull the trigger, the hobby press produced a couple of fine in-depth articles articulating the strengths and short-comings of the dual-engine locomotives. Thus, we elected to shelve our project for a period. Well four years have passed, and we hope you'll still find the photos interesting. -- Union Pacific Doubles Down
Several years ago, General Electric's 45-Ton centercab was the central focus of a locomotive profile; a photo of U.S. Army #8505 accompanied the short article. Ironically a note arrived last week from Belgium describing briefly one of USA 8505's mis-adventures.
Please remember to stay safe when trackside!
