Knockmore Junction - signals-track-lamps

[Antony]

Here's some useful info for modellers of the Great Northern. For Harry Mulholland's layout Thomas McGauran measured the signals, lamps and wrote a treatise on the signalling of many stations on the main line. First, here are details of signals -

Next are two track layouts, pre- and post- 1958 followed by alterations in 1961. Then Thomas' sketches of GN lamps. I'll include a photo from Harry's layout where the signals and lamp can be seen.

Lots of info there and a lovely model of the signal cabin.

Thanks for sharing.

Great info there @Antony, thanks for posting. It's rare to get that amount of text with the signalling diagrams, following the description of the changes gives a good insight as to how it all worked. Am I right in thinking that in later years (post 1977?) the line from Ballinderry/Antrim ran parallel to the up and down main lines and only connected up further along the down main towards Belfast?
