Couldn´t find any info regarding this. But I´m sure someone on this board can answer. What lights for which service and direction must be lit here? What´s the correct pattern? I see this kind of signaling not only on the Class 20 but also on other locos of that era. Whistler as an example.
Could this be the headcode from Spirit of Steam? It looksto me like this Class 20 is hauling the Royal Train http://www.wheeltappersdccsounds.co.uk/page72/index.html This has the classes of train that I am thinking of.
Great many Thanks! Royal Train? Yeah, that would be the corresponding lamp code. But no, I turned the discs manually just for the screenshot. I´ve just used the wrong search terms to find some info. Non-native english speaker ... and all that. "British Rail lamp and disc headcode" brings it all up.
