Union Pacific says its No. 844 steam locomotive will leave its Cheyenne, Wyoming, base on Oct. 13 for a round trip taking it through nine states, going as far south as Memphis, according to Trains Magazine. It will steam through Maplewood on the way.

The train is scheduled to depart Kirkwood station headed for St. Louis at 12:45 p.m. on Tuesday, Oct. 18, running south of Deer Creek, in Webster Groves, then into Maplewood along Greenwood Boulevard.

It’s due into downtown St. Louis at 1:30 p.m., overnight there, and depart at 8 a.m. on Wednesday. See the full schedule.

The engine was the last steam locomotive delivered to Union Pacific, built in 1944. It was originally built for high-speed passenger work. Commercial Union Pacific steam operations ended in the late 1950s, according to Wikipedia.
