To be honest with you, I don't remember that particular milepost you asked about. However, I do know of a "whistle post" on the Attica Branch near the intersection with the Greenway. This marker is the classic "W" that is sort of a stencil design in that the "W" is cut out of a round steel plate. This sign would weigh alot and I don't think it could be removed and moved by hand. It would be a nice addition to a museum collection. By chance I was up on the Attica Branch railbed near the Genesee River trestle this afternoon overlooking the vast Barilla Plant property with all the earth moving equipment parked a half mile away. The old right of way has been greatly cleared off in anticipation of the whole embankment being removed to be used as fill to build up the pasta plant and warehouse above the Genesee River flood plain. I was able to "steal" an old railroad spike as a souvenir before its all gone. It wil be very nice when the Greenway Trail is finally extended from the awesome Genesee River Trestle west to the main trail at Canawaugus. Note that the wye at Avon was immediately abandoned and removed following the Conrail takeover at the same time as the rest of the Attica Branch was abandoned. I'm thinking the LA&L can turn the locomotives in Henrietta at a wye near and behind Southtown, but maybe I'm wrong.
