Harlington Locomotive Society

The Harlington Locomotive Society operates a half-mile track with dual gauges of 5-inch and 3.5-inch for miniature locomotives. The line runs through orchard grounds in a figure-eight pattern and includes a brick station, signal box, workshop spaces, and steaming bays where engines are maintained.

The facility was established to promote the operation of miniature locomotives and preserve the engineering skills of their operators. The signal box and its weight-activated system from the 1950s represent an early form of automation in miniature railway technology.

The railway connects to the engineering traditions of this area, where major industries like HMV, EMI, and Fairey Aviation once operated. Visitors can sense this heritage as they move through the grounds and observe the members' dedication to hands-on craftsmanship.

Train rides operate on specific days from April to October, so it is worth checking the schedule before visiting. The grounds are easy to walk around, and there are spaces to sit and watch the trains move along the route.

The locomotives trigger signals along the track through a built-in weight system rather than electronics, a practical solution that reflects the ingenuity of the members. This simple automation method shows how enthusiasts created clever engineering with the tools available to them.
