The Science Museum of Virginia will bring back its longtime Model Railroad Show from Nov. 28-30, offering three days of train-themed displays and activities that have become a holiday tradition for many families.

The show, now in its 48th year, fills an entire room of the museum with detailed model railroad layouts built by Virginia hobbyists. This year’s program includes eight installations in HO, N and O scales, along with a Lego display featuring playful scenes ranging from Star Wars characters to UFOs.

Visitors may also see a blacksmith demonstration using tools similar to those once used to craft locomotive engine parts. Some will be able to participate in forging. Museum educators will present a train physics demonstration throughout the weekend, and The Forge makerspace will offer a collaborative hands-on train scene build.

The model train room opens at 8:30 a.m. for Science Museum members and 9:30 a.m. for the general public. The final ticket will be sold at 4:15 p.m. The Model Railroad Show is sponsored by Sabel Systems and CSX.
