The railway, just 2.5 miles (4 km) long, ran along the valley of the river Cam.

Cam station was situated at northern end of the village, close to the cloth mill of Hunt and Winterbotham, to which there was a siding.

[2] The station opened with the line in 1856 and consisted of a single platform with a brick building and a wooden goods shed.

Journeys between Coaley Junction railway station and Dursley took only 10 minutes and around half a dozen trains were provided each day, with excursion traffic in the summer.

Goods services at Cam also finished then, but the line remained open to goods traffic from Dursley under British Rail regularly to 1966 and irregularly to 1968, and even after that the line was retained as a private siding, finally closing in 1970.
