Meet Frosty, a Class 55 Deltic with a new experimental metal type called "Wobblemetal." What is Wobblemetal anyways? Wobblemetal is a type of metal that simulates human-like fat distribution.

She's the first engine on Sodor to have this type of metal fitted and maybe some others will have this metal type in the future...

You can feed Frosty, inflate her, milk her, do whatever. If she doesn't get something to eat she'll refuse to move! Damn metalic whale...

If the people legit want to see more Wobblemetal engines, or even other types of vehicles ill make them, I have some on the backburner ready to make
