Operation of Entrance/Exit Panels

You may well not of heard of Gatestown Panel signal box but a series of six short videos were filmed there to explain the operation of Entrance/Exit panels (commonly called NX panels). As you scroll down the page you will see from each sub-heading what each module explains.

Gatestown is, of course, fictional, but it does exist within the Training Suite at Network Rail's Rail Operations Centre in York. It does, therefore, fill an essential need in training signallers who are either newly appointed or converting their skills from mechanical signal boxes.

These videos are intended for viewing at a maximum screen resolution of 1920 pixels wide by 1080 pixels high. Please be aware that viewing at a larger size may result in a loss of clarity and a 'grainy' appearance.
