Our Diesel Locomotives

Until the first diesel was purchased, motorcar M-1 had been used to do switching in the yard. Realizing the importance of this machine, M-4 was purchased to take over regular switching duties. Other diesels were purchased including the similar M-6. In the 1990's, a group of four GE center cabs was purchased. One of those became M-7, and the other three were eventually sold.

	No. M-4 Built 1947 Plymouth M-4 is a 2-axle Plymouth diesel-mechanical purchased during tourist years to perform switching duties when firing a steam locomotive was not practical. Here M-4 pulls #15 out of the roundhouse for crews to install new tubes in the boiler during her overhaul.
	No. M-6 Built 1969 Plymouth M-6 is very similar to M-4 with the addition of air and some extra weight. This critter was brought back to life in 2005 and since then can be seen on weekdays doing light switching. M-6 is parked infront of the coaches after a switching movement.
	No. M-7 Built 1964 General-Electric This General Electric center-cab switcher was originally built as a 50-tonner, but a previous owner increased its weight to 55 tons. It is diesel-electric and is used as our heavy duty yard switcher and occasionally must substitute for a steam engine.
