Added "operational features" section; added text to description

== Operational Features ==
Arley is one of two signal boxes on the SVR that can be switched out, the other being [[Hampton Loade signal box|Hampton Loade]]. When the box is switched out the Down 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.
