I have one. I wish that it was TMCC/Legacy as that is the system I use, essentially. I am looking long and hard at an ERR upgrade. But, the PS2 (in this loco at least) works so well that I hate to rip it out....but I probably will. I did that to an MTH Niagara, but its PS2 was faulty anyway.
"I am very fond of my MTH 20-3128-1 "P&LE" A2a Berk. I get a kick out of running it at the local toy train shop when a NYC fan sees it and drools thinking it is a NYC Berk they did not know about."
Technically, they were P&LE locos, and the P&LE was controlled by the NYC, but never merged into it. The P&LE exercised some independence in motive power decisions and even appearance. Heck, the A2's were green with - originally - gold lettering. Wow. Grey and white and silver and black was what the NYC typically used. But, the A2 was designed by Kiefer, head of NYC motive power design (he gave us little items like later Mohawks, Hudsons and Niagaras). It was well-suited to its task, and is continually under-appreciated. Also, it was thrown in the water just as the diesels began to swim around big time. Short-lived, like the Niagara. It was essentially a steam version of a heavy road-switcher, and, with its train, serve industries up and down the line, even doing some of the industrial switching, I have read.
My favorite 2-8-4.
