I am currently producing 1 x "Model railroad" from 1 x "High-grade steel"
From the wiki 1 x "Model railroad" should be made from 1 x "Plastic" + 1 x "Electronic components".
The portal has 1 x "Model railroad" from 1 x "High-grade steel".
Is there some mix-up between "Model railroad" and "Metal train"?
