[4] Through WTC, Amtrak presently shares ownership of Union Station with the United States Department of Transportation.
This allowed Virginia Railway Express to threaten a filing to the Surface Transportation Board to enforce its right to access when Amtrak tried to oust VRE from Union Station after VRE said they would not automatically re-hire Amtrak as its operating contractor.
][citation needed] One of the rare locomotives used by the WATC in the past was a FAUR road switcher made in the Socialist Republic of Romania in 1974.
This example was made with the specific purpose of testing it on the American railroad network, at a time when diplomatic relations between the Eastern Bloc country and the United States were at an all-time high.
The unit, originally numbered LDH125-107 and nicknamed "Quarterhorse" was tested across the country, but was turned down due to the lack of interest in diesel-hydraulic traction.
