by the Navistar International Corporation (formerly International Harvester). The body was primarily constructed of aluminum which was donated by Alcoa, which has an aluminum processing factory in Lafayette, Indiana. The aluminum body was fabricated and installed on the chassis by the Wabash National Corporation, also of Lafayette, Indiana. Like the Boilermaker Special III, the Boilermaker Special V had pneumatic brakes. However, there was neither a trailer hitch nor pneumatic brake fittings at the rear of the vehicle. As a result, the trailer introduced in 1956 could no longer be towed. The brass bell from Boilermaker Special I and the brass whistle from Boilermaker Special III were installed on the boiler. A five-chime freight train horn from a Norfolk Southern locomotive was installed on the body. The coal tender was large enough to seat up to 14 passengers. The Special was able to "kneel", which allowed children and the elderly easier access to the coal tender. Despite the extensive use of aluminum in the body, the Boilermaker Special V weighed 10,800 pounds (4,900 kg), nearly 1,500 pounds (680 kg) more than the previous version. The Boilermaker Special V was the first to feature an Arabic number "5" on the front of the boiler directly below the headlight. Boilermaker X-tra Special VI X-tra Special IV was later disassembled to make way for X-tra Special VI. Joe Peñaloza, a Purdue University graduate, designed the VI. It was built on a Club Car golf cart chassis, which was donated by Angel Hills Golf Course in Rossville, Indiana. The exterior body was made of a fiberglass composite, donated by Brunswick Tech. The structural work was done mainly at Wabash National. The fiberglass body was formed by Dr. Ray Thompson and his aviation composite materials class at the Purdue Airport. The paint was applied by West Coast Customs and donated by Valspar Corp. Pyramids Sign and Design completed all the detail paintwork. Many of the other materials used in the creation of VI were donated. These items include the brass, which was donated by ABC Metals Inc., bagging material was donated by Decomp, specialty foams donated by Diab, resin used before painting donated by Resin Services, and the lights and safety devices were donated by TSD. The X-tra Special VI was dedicated Saturday October 19, 1996 at the homecoming game against Ohio State at the end of the half time show. The X-tra Special VI was
