Doesnt Harrogate - York have some semaphores? Newcaatle - Carlisle has mechanical interlocking but i dont know if it still has semaphores.
At Blea Moor, Running line signals are all colour light but there are semaphores on the loops, I think. Horton in Ribblesdale down intermediate block are colour light, so after the down distant at Settle Jct, running signals are colour light till the down home at Garsdale. Similar for the up but I dont think there are up intermediate block signals between Blea Moor and Settle Jct .
