Changes

The box was built in its current position in 1883, and has not changed significantly in that time, with the exception of modifications to the lever frame. The box previously controlled access to colliery exchange sidings, the site of which is now the Engine House. Two ground frames once existed in the section to Hampton Loade, allowing access to [[Alveley Sidings]], namely Alveley North and Alveley South ground frames. An intermediate token instrument was provided to allow trains to be locked in to these sidings. The North ground frame was taken out of use in 1974, whilst the South ground frame survived until an unknown later date, released on the Highley-Hampton Loade token.

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 signal box|Arley]] (short section) or [[Bewdley North signal box|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, and an intermediate token instrument is provided to allow trains to be locked in. In the Down direction, the section is to [[Hampton Loade signal box|Hampton Loade]] (short section) or [[Bridgnorth signal box|Bridgnorth]] (long section). The Highley-Bridgnorth long section token unlocks a 2-lever ground frame at [[Eardington]], allowing access to the siding located there.
