be pushed backwards by the Boilermaker Special. It always had to be towed in a forward direction. If it was necessary to move the trailer backwards, the trailer had to be completely disconnected from the Boilermaker Special and manually pushed backwards while being manually steered with the towing yoke. In later years the trailer was infrequently used. It was retired and scrapped in 1993 when the Boilermaker Special V was introduced. Beginning with Boilermaker Special III, the Boilermaker Special had sufficient seating capacity in the "coal tender" area to accommodate most groups. Boilermaker Special V was neither equipped with a trailer hitch nor pneumatic connections to supply the trailer's brakes. As a result, the trailer could no longer be towed and was no longer needed. Boilermaker Special III In 1960, the Boilermaker Special III was introduced. It was built in Detroit by the General Motors Corporation on a 2-ton GMC Buick chassis. It was initially powered by a 6-cylinder gasoline engine connected to a two-speed manual transmission. A single rear axle with dual wheels and a manual-shift, two-speed differential rounded out the drive train. It also featured a pneumatic brake system. A trailer hitch and pneumatic fittings were at the rear of the vehicle to tow the trailer introduced in 1956. Boilermaker Special III featured an all-new body that was much larger and visually different than the Baldwin-manufactured body used on Boilermaker Specials I and II. The cab and coal tender were constructed of plywood with facings of sheet steel on each side. Forward of the cab, the body was heavy sheet steel and steel plate. The brass bell originally installed on Boilermaker Specials I and II was installed on the boiler. A new headlight was installed at the front of the boiler. It featured a standard automotive 12-volt marker bulb reflected by a large parabolic mirror. It was so bright it could only be used during parades. A locomotive air horn was installed on the top left side of the cab. When the horn was sounded, the Boilermaker Special III could be heard from miles away. To complete the locomotive theme, "steam" could be sprayed from the smokestack. The steam was actually carbon dioxide released by the driver from a fire extinguisher cylinder within the cab and plumbed to a nozzle just below the top of the smokestack. The body featured a full 12-volt negative ground electrical system powered
