English: The Pioneer is one of the first two locomotives bought by the Bangor and Piscataquis Canal Rail Road. This engine was bought between 1833 and 1836 from the Stephenson Locomotive Works, Newcastle-on-Tyne, England. Stephenson was one of the early locomotive builders in England and produced most of the best locomotives in the world. The Pioneer, a drop-hook style engine, weighed 7.5 tons, was 18 feet long, burned hardwood, and could travel at 12 miles per hour. This engine is thought to be the first steam locomotive operated in Maine. This photograph was taken after the engine was taken out of service.
