So I saw two interesting moves on the PVL today, January 1st. The first was an equipment move, two trainsets coupled back to back running express through Westwood, towards Hoboken... A four-car set with a PL42 followed by a six-car set with an ALP45dp. However more interesting was the next train to follow just 5 minutes or so later. A four car set with a PL42, going towards Hoboken, cab car leading, except it was three cars, the PL42, and then another cab car #6071, coupled to the nose of the pl42, with the cab end trailing to provide marker lights. Anyone know what that was about? Looked to me like two working cab cars on one train?
