First service June 21, 1942. Streamlined in 1946. MoPac's second streamliner, replacing the Scenic Limited, a heavy-weight passenger train, along the same route. This train was the first MoPac train to use dome cars. This was a very profitable route, earning it's initial cost of $1.4 million in just 290 days of operation. Primarily a night train, but the final two hours (between Pueblo and Denver) offered spectacular mountain scenery along the Rio Grande Western lines.
