Sodor Tramways is a company serving Great Waterton and other nearby villages. In earlier years, as road traffic increased, traffic on the Sodor Tramway decreased, and it was closed down.
Soon after the rediscovery of Great Waterton, the Sodor Tramway Company came back into business. Toby discovered the sign while taking some workmen. Flora is currently its only known locomotive, though Toby himself appears on the sign for the tramway.
