Boston and Maine 4-4-0 #494 is the only surviving B&M 4-4-0 from the Manchester Locomotive works in Manchester NH. The Locomotive is on display at White River Jct, VT. This engine would be great to restore to operation. Heres a pic of it.
Also, wouldint it be neat for it to power excoursions between Manchester and concord? that would be cool to see.
