I model my home town short line of the Tallulah Falls Railroad. It operated from 1871 until 1961. It ran from Cornelia Georgia to Franklin North Carolina. It spanned 58 miles with 48 trestles. All the trestles were wood except the Tallulah lake trestle which was steel and concrete. Here's one of the six hopper cars I built to haul stone from Rabun quarry.
