Tinplate Art posted:Mine had a lurch in Odyssey mode and the pantographs would pop-up from the normal positon and look wrong. Others have mentioned these problems.
I have the early TMCC version and it has a "speed step jump", but it is not to be confused with the early Odyssey lurch that Lionel had in locomotive produced in the early years or 2000-2002. I was able to smooth this speed step jump by keeping the wheels clean and running it with a CAB 2 in TMCC mode.
The pantagraphs are very fragile and as discussed before they tend to break. Not sure if there will be a more robust solution with this release.
