B&O color position light signals

Reading about the new signaling on the old Alton Route to St. Louis suggested the days that Washington Union Terminal used these color-position-light signals, as well as Staten Island Rapid Transit (where one could look out the front train-door window next to the engineer's cab, like on NY subway cars).   Sorry to see them go and hope a few will be saved for historic operations at Union or other museums.

 I recall them being used along the ex-Buffalo, Rochester & Pittsburgh lines, where they replaced semaphores after B&O took over. When Genesee & Wyoming bought the Rochester line, the signals on the that line had been removed by B&O prior to its becoming the Rochester & Southern except for the approach signals for the PRR/PC/Conrail crossing at Machias Junction and Ashford Junction. The Buffalo line had only advance signals for Ashford Junction, and the approaches to East Salamanca yard. South of there, the line was fully signalled at least as far as Punxsutawney. Last time I looked, the signals guarding the approaches to East Salamanca were still in use, as well as at Ashford Junction, but they are on very borrowed time.
