This model is a New Haven Railway reskin of Dick Cowan's Alco RS3. You can download the freeware model at: http://dickyjim.com/diesel.html. I painted it for the awesome Virtual New Haven Springfield route.
The Alco RS-3 locomotive was delivered in three groups to the New Haven; 517-536 in 1950, 537-546 in 1951 and 547-561 in 1952. All units were 1600hp but the first group was characterized by a solid handrail across the pilots. As on many other railroads, these units performed yeomans work - hauling both freight and passenger consists to the end of the NH.
In the scenario editor it is listed as: NH-RS3_sl_db. A No Crew version is also included and has NC attached to its name in the scenario editor. This model is installed into: Assets\Britkits\ Alco\RailVehicles\Diesel\ RS3\NH.
Unzip and install using the included RW_AssetSetup.exe installer.
