In 1959 and again in 1963 I rode the Denver Zephyr from Chicago to Colorado Springs. Some cars from the DZ were attached to the Royal Gorge for the trip down to the Springs. Eastbound trains (from the Springs to Denver and Chicago) left from a different station. How did the cars get from one station to the other? Were the cars wyed? Were they cleaned? Did the same on board crew work east the same day? Did the Rock Island train use the same stations? Last time I was there both stations remain in beautiful condition. Thanks.
