Front or Rear?

For Union Pacific's wooden cabooses, the offset cupola end was toward the front. The conductor's desk was at the rear. The caboose was usually placed so the the conductor sat at his desk and faced toward the rear. The rear brakeman was up in the cupola, facing forward, to watch the train. UP's CA class (built 1905-1913) and CA-1 class (built 1914-1925) wooden cabooses had wooden passenger benches ahead of the cupola, two on each side. The toilet was in the right front, and the ice water, wash water and wash basin were in the left front. The stove was on the right side, between the cupola and the conductor's desk.

UP's steel cupola cabooses had centered cupolas, without passenger benches. The first were built in 1942; the last in 1975. The conductor's desk was on the right side, at the rear. The toilet, and its small window and rooftop ventilator, was on the left side, just ahead of the cupola.
