I guess this the best place to post this question, even though it predates LA&L ownership of the B&H by 80-100 years. What kind of signalling did shortlines/branchlines like the B&H use when multiple trains were operating? Keuka Lake Memories mentions that the B&H sometimes ran as many as 8 trains per day during the busy summer excursion season. What system(s) did they use to avoid collisions and keep the trains on schedule? I've walked the entire original mainline and I've never seen any evidence of semaphores or lighted signals...
