The Grade II listed ground frame shelter at Hammerton Station can be seen on the platform still in use in January 2020.

Ground frame shelters

At all six of the Forge Valley Railway stations, there were never signal boxes. Instead, a ground frame was positioned on the platform. Underneath the platform, there was a gap where the signal wires and point rodding would lead to the points and signals within the ground frames control.

The ground frame itself was covered by a wooden shelter, with double doors at the rear. This arrangement wasn't unique to the Forge Valley Railway, being found at several stations across the southern region of the North Eastern Railway network such as some on the Malton & Driffield Railway.

Although there is some contradiction to its authenticity, incredibly a single example still exists and even more hard to believe, it continues in use on the national network. This survivor is at Hammerton on the York to Harrogate line and is now Grade II listed. It closely resembles those which would have stood on the Forge Valley.
