With regards to the LIRR conversion of their permanent crossover frogs to the swing nose frogs, I came across this Old Saybrook, CT photo of an early switching frog dating back to 1909. I'm sure it was manually controlled, but it looks like the concept is not a current one. Can anyone comment on this?
Mineola, NY is my real home, however I live 60 miles from Mineola, MO. No LIRR here!
