thomas and friends mini series

That's what I thought. Normally they show only two waves in the inserts. I think this time they put everything in this insert by mistake.
I think these are all we will see in 2020. If you break them each wave it comes out to about 9 to 11 new engines per wave plus rereleases unless they release many more new ones with each wave this year.

Mike, you are right, cant tell from this picture though. Sun, does Thomas have any markings on that silver one?
