A machine room on wheels. That's my first impression every time I see a Shay Locomotive. The vertical cylinders, the massive drive shaft, the open gearing and the steam wafting out everywhere all combine to form an image that just doesn't immediately say "railroad engine". The ultimate incarnation of that image is the brutish, 162 ton Western Maryland #6, seen here switching cars in the yard at Elkins, WV during a special excursion in 2008. For those who've never seen this monster, you don't have to wait for a special excursion. She makes regular appearances hauling tourists on the Bald Knob run at the Cass Scenic Railroad, and she's well worth a visit!
