A Union Pacific derailment resulted in cancellation of the Winter Park Express between Denver and Winter Park, Colorado, last Saturday.
Amtrak spokesman Marc Magliari told Trains magazine that about 500 seats had been sold for the trip that was canceled.
The westbound California Zephyr was held for more than four hours at Denver before it was permitted to proceed. It lost another two hours waiting for the tracks to be cleared at the derailment site.
The derailment did not materially affect the eastbound California Zephyr on Saturday. The ski train operated as scheduled on Sunday.
News reports indicate that 10 empty freight cars on a UP train derailed on a curve on the Moffat Subdivision.
