For a complete listing of VRE information, including detailed locomotive and passenger car rosters, visit the official VRE homepage.
This photo archive was inspired by Charles Biel's photo archives of the Burlington Northern, the SANTA FE Super Fleet, and the Burlington Northern Santa Fe. They are great railroading resources. Check them out.
Most of the VRE locomotives are of CSX lineage and Dean J. Heacock's CSX Photo Archive has a good view of these locomotives in their prior freight service lives.
Also for railroad roster information check out R. Craig's Motive Power Rosters. It is handy information for identifying locomotives.
