I'm usually around the NJCL around evening parade time, west of Long Branch, so I see a lot of it, or try to.
Most, if not all, MLs out of NY Penn ran locomotives on the west end. Eastbound morning trains I see are usually in push mode, in pull mode coming home.
Lately, a few of these MLs are running push mode westbound. Wasn't the operation keeping the locos on the west ends of these NY trains? Does it really make a difference? I was told once that trains leaving NY had to have the power on the west end. Has the equipment and personnel shortage and other problems caused a change in operations?
