Features the September 1990, five day trip of the 3985 across Nebraska from Cheyenne to Council Bluffs for the 1990 River City Roundup. This was the first run of the Challenger after being converted to oil and we start off by featuring her pulling a 128 car freight out of Cheyenne to North Platte. Then she pulls the River City Roundup Special to Omaha. On the return trip she once again pulls freight this time from Council Bluffs to North Platte followed by pulling another passenger train the next day. Features five days of action, tons of high speed pacing, and runby after runby.
