Highley Signal Box (HY) is an original McKenzie and Holland Type 3The British Railways classification for diesel locomotives of 1500 bhp to 1999 bhp signal box, built in 1883. It is situated opposite Highley station.

Operation and Equipment

Lever Frame

Highley retains its original 14 lever McKenzie and Holland 1873 patent lever frame, with 11 working levers, 3 spare, and no spaces. The interlocking was replaced in 1903 with more standard tappet interlocking by the GWRGreat Western Railway.

Block Sections

The box works in both directions using Electric Token Block regulations, and is fitted with four Tyer's No. 9 token instruments. In the UpIn reference to the direction of travel means towards the major terminus (i.e. towards Kidderminster on the present day SVR) direction, Highley works to either Arley (short section) or Bewdley North (long section). The Highley-Bewdley North long section token unlocks Arley as a ground frame, allowing for access to the yard when that box is switched out. In the DownIn reference to the direction of travel means away from the major terminus (i.e. towards Bridgnorth on the present day SVR) direction, the section is to Hampton Loade (short section) or Bridgnorth (long section). The Highley-Bridgnorth long section token unlocks a 2-lever ground frame at Eardington, allowing access to the siding located there.
