Here we see a wooden Fitchburg & Leominster Railroad wing plow needed to clear the line and push the snow well back to make room for the inevitable next snowfall." - Fletcher, David H. 'The Portland Company 1846-1982. Charlest, S.C. : Arcadia Pub., 2002. 41. The Portland Company built this plow for the Fitchburg & Leominster Railroad, January 2, 1886.
