To all:
There was a recent thread about the letter "G" on a signal mast on the Westbound Montauk (east end of the Receiving Yard.) Someone mentioned that it was an indicator as to where Gas lines were present under the tracks. I found out (from a reliable source) that the signs are in fact Grade Signal markers. I know that the only 3 grade signals are on Montauk 2 (3rd, 4th and 5th block signals east of Bliss), but these markers were used for contact shoe scrapers. In the past, M of E would install shoe scrapers on contact shoes for the purpose of scraping ice off of the third rail. They were installed on the WB Montauk and then the equipment would proceed west and trail into Montauk 1 to enter the main track. As the train proceeded east on the WB Montauk, the "G" would indicate the presence of the uphill grade. These shoe scrapers are no longer used as it was found to cause damage to the third rail.
