Wow! Cool engineering, thanks Alex. For those that want (or have seen) this engine run, we (TCA Midwest Division) have been running this set at Trainfest in Milwaukee for the past several years.
The two sets that I have been directly involved with work fine if carefully set up. It's amazing how many knob jobs say "oh, that's the Acela, I heard it does not run well" when one is operating right in front of their fat face. Must be a problem engine because the Internet said so...
Maybe learn to read the instructions, now there's a thought.
