A friend of mine recalls seeing track pans / water troughs in use on the NYC's Chicago Line, but since he was very young at the time he can only recall that the location was somewhere to the east of Rochester (likely within Wayne County, or extreme eastern Monroe County). I know that there were track pans in use in Palmyra, but were there other locations in this general area? Also, how soon after dieselization would the track pans have been removed? Thanks for any help!
