Big Mo was originally made to promote Lionel - Neil Young was frequently seen with it at York. I first saw it at the Greenberg show at Hofstra University - I think about 25 years ago. A neat promotional layout on wheels!
MTH took it over and, again, brought it back to York. If one looked carefully he would see several places where the Lionel name and logo were painted over. One example was on tunnel portals.
It dropped out of site shortly thereafter. Wonder where it is now, if it still exists
