The Weeter Mining Company has two coal loaders located on Moose Valley
Routes, and is a wholly owned subsidiary of Moose Industries, the holding company for both
the Weeter Mine and the Moose Valley Railroad. Weeter Mine No.1 is located near Potomac
Jct, on the Moose Valley Mainline Subdivision, and Weeter Mine No.2 is located near
Okonoko on the Baltimore and Ohio Railroad Cumberland Subdivision. Weeter Mine No. 2 is
the larger and most modern of the two facilities. Wedged between the B&O mainline, and
Backbone Mountain, this facility generates a considerable amount of Bituminous coal used
by power concerns in the Mid Atlantic and Northern Tier power grids. Moose Valley trains
pick up unit trains usually using B&O or WM (Western Maryland) hoppers which are
leased from those roads by the Weeter Mining Company. A Weeter Mining 
Company
switch engine is stationed at the plant, and performs all loading operations. Road trains
back their empty hoppers into the yard lead after dropping the caboose on the main, and
then cut off. The road units will then retrieve the caboose and run light to Berkeley
Springs or Greenspring Yard depending on current needs. After the Weeter Mining switcher
loads each car, the cars are then retrieved from the storage yard and a loaded train
assembled on the yard lead. After the loads are positioned, a MV road crew will pick up
the cut and assemble the train with caboose on the B&O main. The train will then
operate as a Northbound symbol freight such as MV20-U.
