Operational Features

Arley is one of two signal boxes on the SVRSevern Valley Railway that can be switched out, the other being Hampton Loade. When the box is switched out the DownIn reference to the direction of travel means away from the major terminus (i.e. towards Bridgnorth on the present day SVR) Loop cannot be used.

Unusually, when the box is switched out the yard can still be accessed, by operating the signal box lever frame as a ground frame. An intermediate token instrument is provided to enable trains to be locked into the yard. One side effect of this operation is that whilst the yard is being shunted, the Highley and Bewdley North signalmen are unable to communicate by bell signal.

History

Before preservation, the original signal box had a 14-lever frame with no switching out facility. Other minor changes include two stacked disc signals at the toe of the yard points as per normal GWRGreat Western Railway practice, and a bracket for entry to the yard at the up home signal. A diagram is available on the signalbox.org website.

The signal post of the DownIn reference to the direction of travel means away from the major terminus (i.e. towards Bridgnorth on the present day SVR) Home signals was originally the signal post of the UpIn reference to the direction of travel means towards the major terminus (i.e. towards Kidderminster on the present day SVR) From Shrewsbury Home signals at Bewdley North. It was originally located at the south end of Wribbenhall Viaduct, somewhat further south than its modern replacement.
