The folks over at Freighthouse Square tell us, and we quote, "a bazillion" model train aficionados will converge on Tacoma's Dome District this weekend for the TNW Model Train Show - packing the beloved long building with kids of all ages. Expect train layouts and vendors on three floors of Freighthouse Square, not to mention a LEGO play area. Expect everything a model train lover could ever dream of. Also, expect approximately a bazillion people.

[Freighthouse Square, 9 a.m. to 5 p.m. Saturday, 10 a.m. to 4 p.m.  Sunday, 2501 E. D St., Tacoma]
