Lionel was so close on this, I still don't know if they realize that the revised version is still wrong by convention(unless you consider it a two-train transformer, which some do use the accessory posts for a trolley or motorized unit).
The new practice of coloring the binding posts / banana jacks was and is throwing off a long standing policy at Lionel of using "A" as common and "U" as center rail power for 1 train transformers. There never should have been two "U" posts on the CW, that was a big blunder.
The way they should have been built originally and forever is with two common black "A" posts(although only one is really needed), a red "U" post for track power, and a red "C" post for accessory power. Even better, no colored posts at all, except the new upcoming FasTrack came with color coded track wires.
So the early version really only needed to be re-labeled, and the whistle/bell button functions switched. There you go - a modern 1033(less one fixed voltage tap/setting).
And, how very true about the manual(s). Lionel had to back-peddle and issue warnings that the CW was not compatible with common ground track activated accessories. Yikes, to put it mildly. Fortunately, the revised version is OK with this.
