Space And H. Project S999 was a character I made up. S999 stands for Steam 999. He was a big strong tender engine who got converted into a tank engine by scientists.He is sad he isn't a tender engine and pulls a truck that looks like a tender. He is special by combining the power of a tender engine and "tankifying it" (that means turn into a tank engine) into a tiny engine.He got 999 from how many dollars it costed to make him from scrap.His funnel is still the same scrap funnel from the year 1899.He also is kinda like James (from Thomas And Friends).He was Experimental but now is a regular locomotive.
I used the model from "James The Tank Engine" from @Domix258
