The largest model railroad at the Bellingham Railway Museum is our G gauge layout depicting logging and mining railroads. G gauge, otherwise known as Garden Railroad scale, is the largest of the indoor trains. The engines feature realistic sound which can be heard throughout the museum as they thunder down the track. Our layout has both standard and narrow gauge trains and features Shay and other logging locomotives with their unique gear drive system. A number of other steam and diesel locomotives pull freight and passenger trains around the large layout. Children and adults 7 years of age and older may operate the trains on 2 separate tracks. (Children under 7 may operate the trains with special care and constant parent or guardian supervision.) The G gauge layout is always a favorite for train enthusiasts of all ages.
