Euston new lines?
You're getting close!
This system was also an experimental system introduced by the L.M.S. in the 1930s, but not on the Euston New Lines.

I think it's time to knock this one on the head!
The answer I was wanting was the Speed Signalling experiment which the L.M.S. undertook in the Mirfield area from the 1930s-1960s - a complicated system which even allowed for four seperate lights to be lit vertically on the one post - understandably it was scrapped when other modern signalling systems were introduced in the 60s and 70s.
Ralphchadkirk came closest with his suggestion of the L.M.S. signalling on the Euston New Lines - again of an experimental nature and at about the same time, so I'm going to declare him the winner, and if he doesn't want it, it's an open floor.
