i've heard of the wada works gp9 and i think they did a turbine powered f unit and some gas powered zephyrs and they are super cool i had always had that idea of a g scale gas powered railway since i want to run it in snow and not worry about my electronic stuff like transformers getting wet.
is there anyone else that makes gas powered g scale diesels outside of wada works
and what would be the price for undecorated units
