The sidings at the north end of the loco sheds once served the Finedonhill Tramway a narrow-gauge railway that carried iron ore from quarries to the south of Finedon to the sidings. The tramway was in operation from 1875 to 1926.[3] Another narrow gauge tramway, the Wellingborough Tramway passed under the railway immediately north of the Finedon Road overbridge. This line operated until 1966 and was the last narrow-gauge railway operating in The Midlands iron fields.[3]
