66/67 used to carry sleepers. There was the Washington to Boston sleeper, and there was the New York Executive Sleeper, which ran north out of Washington and was dropped at Penn Station in the middle of the night. I worked them both on the Washington extra board in early 1987. The Boston job was tolerable, but I hated the New York job because of poor security after the car was dropped and the rest of the train left. The occupied car was left alone and no security personnel ever checked on us until the passengers detrained in the morning. I was promised a radio in case of trouble, but they NEVER had one for me. The Penn Station folks didn't care.
