I like to visit Model Railroad Crossing, 1113 W Pipeline Road, Suite 125, Hurst TX; phone 817-595-0800; they have a good web site. Buddy is the owner and knows trains (all scales). He is an old time hobby shop man who can answer your questions. Sure, he is retail, but he has an outstanding collection of Micro-Trains cars, plus many hard to find things in all scales. He does close at 5 PM, but open Saturdays. His shop is in a strip shopping center just a couple of blocks South East of NorthEast Mall in Hurst. Enjoy the Golden Oldie rock music while you shop! Hurst is North of Arlington.
