Got some model train nuts in the house? Then you'll want to satisfy their appetite for all things choo-choo this weekend at The Great Train Expo. It's happening on Saturday and Sunday, from 10 a.m.-4 p.m. each day, at the Lausche Building on the grounds of the Ohio Expo Center.

There's going to be operating model railroads, a toy train play area for kids, workshops, layout ideas, and more than 300 tables of vendors offering train and toy merchandize of all scales and sizes.

Admission is $7 for adults and free for children under 12. The Ohio Expo Center is located at 717 E. 17th Ave. in Columbus.
