Marshfield is a small hamlet south west of Swindon its a rich farming area and the residents wantedto get their produce to market more quickly.
They approached the Great Western Railway at Swindon to see if they would be able to help by building a branch line to the area. It took six years of talks befor an agreement was reached and the branch line was built.
The station was only a small one, a cattle dock off the station loop, asiding for the goods dockand shed and siding for the coal yard.
The G.W.R. ran a daily passenger service, a mixed goods with milk and local pick up goods.
The layout is set in the mid thirties and run by the G.W.R. with one engine in steam.
It is built to 'O' gauge fine scale which is 7mm/ft running on 32mm gauge track.
The station building was built by Bob Dawson of York and the rest by the owner, Richard Andrews.
