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 GWR.
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 Up direction, Highley works to either Arley (AY, short section) or Bewdley North (BN, long section). The HY-BN long section token unlocks Arley as a ground frame, allowing for access to the yard when that box is switched out. In the Down direction, the section is to Hampton Loade (HL, short section) or Bridgnorth (BH, long section). The HY-BH long section token unlocks a 2-lever ground frame at Eardington, allowing access to the siding located there.
