very few mfgs. in other scales have diecast locomotives. Most steam locomotives are done in plastic. Of course weight would have to added to any plastic O scale engine.
All diesels are plastic and are well detailed and look great, why not steam engines?
Would it make steam cheaper in price? I don't know but it does beg the question on why it has not been done.
Is it because diecast has been used in three rail from the beginning and change is not one of the strong points in the three rail community? Why not?
Give me your whys and why nots on steam being done in plastic.
