Obsolescence? What could be more obsolescent that a loco with whistle/horn that only goes through a fwd-neutral-rev-neutral sequence, and can only have one loco running on a block/track at the same time? That's late 1930s tech---but it's still popular.
I've reached an age where I expect that most all of my PS2 & PS3 locos will outlast me, and their quality is such that I expect my train-nut grandson will operate them for many more years (right now, he's using one of my original issue Rev G TIUs and an equally old remote). Unlike the competition, with its multiple types of control systems, my 2002 dcs system runs any DCS loco ever made and via software upgrades is also the most-up-to-date.
