Travel with Green Frog through mountains, CSX shops, and a bit of steam on the Western Maryland Scenic Railroad as we follow more CSX operations. This DVD takes you on the Baltimore Service Lane, and the Cumberland Business Unit. The terms 'Service Lane' and 'Business Unit' are CSX's new definitions of a 'Division' although 'Sub-divisions' are still part of each 'Service Lane' and 'Business Unit'. This DVD covers portions of Cumberland, Cumberland Terminal, Keystone and Mountain Subdivisions as well. You'll have an opportunity to visit inside the CSX engine facilities at Cumberland and witness the repair and maintenance facilities. See the first CSX 700, and SD70AC being used for crew training, wheel repairs, and much more. We'll travel the mainline between Hyndman to the west, and Paw Paw to the east, viewing exciting CSX action along the way.
