Your customer/friend is in luck. Impressive layouts are in operation at a depot-like building placed alongside their house in Heber Springs -- RULAND JUNCTION. The building is a home-grown toy train museum filled with layouts featuring vintage Standard Gauge trains, O-gauge trains by Lionel and Marx, AF trains, and lots of railroad lore.

Owners/Hosts are Wayne & Susan Ruland -- great ambassadors for the world's greatest hobby!
In relatively nearby Conway, check out the Central AR Model RR Club at its website: www.trains.buzz.
