That Keuka Lake Memories book has that trolley information. The interchange was at the Penn Yan NC/PRR station off Elm Street. Basin Street is or was too steep of a grade on each side, whew. Plus the grade up Water Street is strenuous. Shouldn't this be in the PRR or NYC thread? FGLK still services PY Tuesday Thursday if that?
Proficient on the Southern Tier Line, The former PRR Elmira Branch, A little LV, A lot of EL, And of course, the Corning Secondary. Someone always knows more than me. Remember the Binghamton yardmaster that routinely said in a high voice, "No! No! No! That's not what I told you to do!"?
