The Edison was an 0-4-0 built by the Manchester Locomotive Works in the 1870's. It was given to Henry Ford by Thomas Alva Edison who had the locomotive in his New Jersey quarry. It was rebuilt by Henry Ford in 1932 in the Rouge shops to represent an 1800's William Mason. The locomotive had been on display in the Henry Ford Museum from 1932 until the early 1960's. It was then placed into regular service in Greenfield Village. The loco was originally oil-fired but was converted to burn coal in the early 1980's. The baloon stack was replaced with a diamond stack in 1993. The wood pilot was also replaced by a steel pilot. In 1997 the old wood cab was replaced with a steel riveted cab. In 2004 the diamond stack was replaced with a straight stack. In 2005 a new cylinder was cast and machined to replace the old one which developed a crack. The eccentric lobes were also replaced and the locomotive re-timed in 2005. In 2007-08 the tires were replaced.
