Those speed recorders on all the axles are a GE thing - they are part of the
anti-wheelslip system. Look at any GE U-series diesel, and you'll see every

This was about the time that EL was doing the PC run-throughs between Cedar
Hill Yard in New Haven, CT and Port Jervis, NY. Undoubtedly, one was
"trapped" in EL service and made its way out west before being returned to
