Automatic Distant Signal at Goraghwood (1958)

Unread postby Wilkinstown » Sun Oct 11, 2015 7:35 am

Alterations at Goraghwood, on the Dublin/Belfast line, in 1958 saw the provision of a new mainline trailing crossover to the south of the station, a new down outer home, a new up advance starter and extensive track circuiting. The down distant was converted to an automatic colour light signal which would clear when all the applicable down main (semaphore) signals had been lowered. It returned to yellow automatically as soon as a train passed and would not again clear until all the signals to which it applied had been first returned to danger and again cleared. This arrangement was unique on the GNR at the time and as far as I am aware was not repeated in this form elsewhere in Ireland.

Would this type of arrangement have been implemented on British Railways around this time ? If so does it still exist anywhere ?

After the abolition of Belle Isle Up signalbox in 1967 the former electric motor operated Up outer splitting distant signals installed on a gantry for the up main and up slow were now operated automatically from Kings Cross , providing new Stop signals with position four route indicators, KC 1 up slow or KC 13 up main were displaying green aspects.As the distant signals were splitting type an individual switch was provided to maintain the slower diverging routes in the On position during foggy weather.I like many contributors have also come across signalboxes some absolute block working where disant colour light signals worked automatically.

A large number of the boxes on the old GCR route had this arrangement from GCR days.
