in 1956 to provide seats for about 30 passengers. Passengers boarded the trailer by a set of stairs at the rear of the trailer. One member of the Reamer Club rode the trailer at the stairs to prevent anyone from boarding or exiting the trailer while the trailer was in motion and to communicate with those towing the trailer. The trailer was similar to a wagon in that the front wheels were steered by a towing yoke. The trailer also had pneumatic brakes which received compressed air from the Boilermaker Special via pneumatic connections adjacent to the trailer hitch. The brakes on the trailer were remotely actuated independently from the brakes on the Boilermaker Special by a hand-operated lever mounted to the right side of the Boilermaker Special's steering column. When it was desired to stop the train, the Pilot had to simultaneously operate the foot brake for the Boilermaker Special and the hand brake for the trailer. While the trailer did provide additional passenger seating, it was difficult to tow. The brakes worked best when the trailer was fully loaded. When the trailer was lightly loaded, the braking action was excessive, which resulted in the wheels locking and skidding when the brakes were applied. Since the trailer brakes were remotely operated by a hand lever, and the Pilot always had to be ready to operate the brakes, the Pilot had to keep one hand on the trailer brake lever at all times while the Boilermaker Special was moving in the event an emergency stop had to be executed. This meant the Pilot was always driving with only one hand on the steering wheel when the trailer was in use. If the Pilot forgot to operate the trailer brakes when the Boilermaker Special's foot brake was operated, the trailer might jack-knife, particularly if more passengers were seated on one side of the trailer. Also, the steering action of the front trailer wheels was not damped, so the towing speed of the trailer was limited to 25 miles per hour. If the trailer hit a bump when above 25 mph, a stable, rapid, side-to-side oscillation was induced in the front of the trailer that could only be stopped by slowing the trailer below 20 mph. This oscillating motion was very uncomfortable and disturbing to the passengers. Finally, since the front wheels were steered by the towing yoke, the trailer could not
