The Gourock layout can be seen here: http://www.opentraintimes.com/maps/signalling/gou

I notice there are two LOS markers. I can see that the one nearer Fort Matilda could be useful for moving a train between platforms 1 and 3. But what is the purpose of the LOS nearer Gourock? (the only thing I can think of is that it might be to allow an engine to run round its train, with the train waiting at the LOS nearer Gourock, and the engine running via the LOS nearer Fort Matilda - though that seems rather unlikely).

The layout dates from the 1980s when trains were not allowed to run with locomotive front and rear. 'Top & tail' is normal working nowadays, and the rounding facility now appears antiquated. The two limit of shunts allows a train which arrived hauled by one locomotive to propel out of P3 to sit inside of 112 signal, and the loco to then detach and run round its train via P3 and signal 108, re-attach and propel the train back into P3.
