The Arkansas Railroad Museum, 1700 Port Road, will host the 24th annual Railroadiana Show and Sale from 9 a.m. to 4 p.m. Saturday, April 6.

Railroadiana is Arkansas’ largest show and sale of railroad memorabilia, according to a spokesman. Each year, several elaborate model train layouts are also part of the show.

Admission is $5 for adults, $2 for children ages 6-11, and free for those under 6 with adult.

The former St. Louis Southwestern/Cotton Belt shops are occupied by the historic collection of railroad equipment. The museum is one of the largest displays of historic railroad equipment in Arkansas. Between the disappearance of SSW in 1992 into parent Southern Pacific and the size of the collection, the Arkansas Railroad Museum can be considered an upper-level railroad preservation facility.

The museum is operated by the Cotton Belt Rail Historical Society and local volunteers. It’s open Monday through Saturday from 9 a.m. to 2 p.m. and on Sunday afternoon by appointment.

The museum is most famous for stabling SSW’s Engine 819, the last steam locomotive built by SSW in February 1943. The 819 was restored to operation in 1986 and operated on 13 excursions between 1986 and 1993. It is currently out of service.

A collection of historical passenger cars, mostly lightweight Pullman-Standard equipment, is also kept for use behind 819. The 819 is listed on the National Register of Historic Places.
