What's is this set?

Yes, there are really only a few Thomas trains left to find, but quite a few of the non-Thomas trains that I must have!! The set that you have is one of them, but I can't seem find a nice used one...then stumbled on this! It's basically the same I think, except it comes with the red engine, and a few less Plakids.

Lol...it would take another lifetime to attempt a "collect them all" non Thomas Plarail collection, so I'm only gonna try to complete certain subcategories, and work towards procuring the ones that I really admire.
