Adds a steam locomotive in the research tree with custom graphics.
It's heavier than the original locomotive, slower acceleration but with higher top speed.

This mod uses the original fuels. If you want an actual steam locomotive I have made a separate mod that injects these graphics onto the Steamtrains mod:

https://mods.factorio.com/mod/steamTrains

HR graphics only at this point.

Respectfully phrased feedback is welcome.

A big thank you to all the helpful people in the Factorio discords mod channel!
