Chasing the NS Meadville Line blindly for my 1st time, lucky for me the 533 goes into emergency prior to this crossing, allowing me to catch up and find this spot. From what I heard on the radio, the EOT was malfunctioning and thought it was losing air. The engineer stopped the train under his own power, and then she went into emergency allowing the conductor to jump off and flag the crossing after 533 'rebuilt' it's air. After 533 cleared the crossing, the conductor isolated the EOT, and placed her flag in the coupler for the rest of the trip to Conway.
