Beginning in 1964, the Rio Grande began attaching a car or two of piggyback trailers to the rear of the Salt Lake City–Denver Prospector in order to boost the train’s bottom line, as seen here at East Rocky, Colo., in April 1964. Nevertheless, the train was discontinued in 1967.

Shades of Southern Railway Piedmont service in the mid ’70s. Always great to see Steinheimer photos!!
