Previous to its use at Disneyland, the engine served the Puritan River Sand Company in New Jersey.
The steam engine was converted to burn biodiesel in 2007, as it is less polluting than oil.
Before the Christmas Holidays at Disneyland, the Railroad announced that the Ernest S. Marsh will undergo a complete restoration like the Fred Gurley. The restoration was scheduled early 2010, but got bumped to a later project.
These types of engines were used most common on American railroads during the 1800s and 1830s until 1928.
