These two Shays are noteworthy because of their shear size. The GC&E #12 was originally built as a 150-ton three-truck Shay in 1921. That was very large Shay then. In 1933 it was enlarged at the Cass, West Virginia shops of the GC&E into a four-truck Shay, probably becoming the heaviest Shay ever. The WM #6 was built in 1945 as a 162-ton three-truck Shay, also one of the largest ever built at the Lima Locomotive Works. The WM #6 only operated in service for eight years and then was placed in the B&O Railroad Museum in Baltimore for 30 years. The GC&E #12 was scrapped at the Cass shops in 1955 following a wreck in 1942. Ironically, the WM #6 is currently operational at the Cass Scenic Railroad.

Not only are the operational histories of these two Shays tied together, but they have mechanical ties as well (see comparison chart on page 5). When Lima designed the WM #6, they drew heavily upon their experience with GC&E #12. Many of the drawings for Order Number 510 (WM #6) are revisions of earlier drawings for Order Number 329 (GC&E #12). The trucks on these two locomotives are virtually identical.
