As I noted earlier, this Atlas version is a very innovative set, especially the design element in which the cars couple magnetically with diaphragm-like car ends.
If it’s not a joint venture with Marklin, it certainly was inspired by the Eurostar train set Marklin made. I tend to think they’re related, however.
I’m tempted to buy a set for one of my grandsons, but he is already enjoying the LionChief set I gave him two years ago. An innovative O gauge set of the Acela, also with children in mind, would be great, but the tooling costs probably would make such a venture costly.
