George L. Carter, builder of the Clinchfield Railway, as well as many of the coal towns of Southwest Virginia and developer of the Tree Streets neighborhood, once had his home on the ETSU campus. Now the George L. Carter Railway Museum is open in the old College of Medicine building, and will be open on Saturdays for the running of model trains by the East Tennessee Modular Railroad Club. Three layouts are on display. A G (large) scale on loan from an Elizabethton benefactor measures 12.5 feet by 12.5 feet. The 44-feet-by-24-feet HO scale layout of the modular club and a 23-feet-by-12-feet N (smaller) scale layout donated by Marian Bankus, of Knoxville, make up the permanent display.
