Tiny trains will rumble through towns and countrysides at the Cotton Belt Model Train Show this weekend. 

Sponsored by the Tyler Tap chapter of Cotton Belt Rail Historical Society, the annual show is set for 10 a.m. to 5 p.m. Saturday and 10 a.m. to 4 p.m. Sunday at the Harvey Convention Center, 2000 W. Front St.

Tickets cost $7 for adults. Children younger than 12 will get in free.

Besides the model train exhibits, vendors will be on hand to sell and and talk about railroad memorabilia, model trains and accessories, organizers said. Free digital command control workshops are set for 10:30 a.m. and 1 p.m. Saturday and 1 p.m. Sunday.

The show brings to the public some of the railroading artifacts and attractions on view at the Cotton Belt Depot Museum, 210 E. Oakwood St. 

The Cotton Belt Depot opened to the public in 1905 and continued service until the last passenger train departed in April 1956. In 1988 the Southern Pacific deeded the depot to the City of Tyler. The City restored the depot in 2003.
