I'm not sure if this brass kit car is still available, I don't see it listed on the Traincat website anymore.
Between 1966 and 1968, Santa Fe's West Wichita shops upgraded 315 all-steel cabooses for mainline pool service. Previously, cabooses had been assigned to individual crews, and were changed at every crew change point. Labor agreements reached in the 1960's allowed cabooses to run-through, but also required certain upgrades. The Ce-1's were equipped with cushion underframes and sealed windows in place of the old, sliding kind originally found on the cars. Taking the cupola end as the rear, the three windows on the right side of the car were initially retained, while the five windows on the left were reduced to four. Within a few years, the arrangement was changed to just two on the right and one on the left.
