GCR will be operating 4 straight days of steam to celebrate the Centennial of the National Park Service. Steam will pull the regularly scheduled 9:30 train on Wed-Sat August 24-27th. We will probably alternate between 29 and 4960 Wed-Fri. The 9:30 train on Saturday, August 27th is a doubleheader.
Tickets are still available for all of those dates. I've proposed running another doubleheader later in the season, and possibly at least one each year until 29 expires on it's 1472. However, if this one doesn't sell out on August 27th, it will be hard to convince anyone to do another.
The Amtrak Exhibit Train will be on display at Grand Canyon during this time as well.
