Hi,

Would it be possible to create a shuttle train "module"? For bobs mods, once you research Railway 2 and 3 unlocking Locomotives MK 2 and 3 the shuttle train is still only MK1 speed. It would be great to have a module to put in the bobs vehicle grid to make any train into a shuttle train

This is a good idea, FARL also did something like this.

I figured out how to make a module that makes any locomotive a shuttle, but it only partially works.

When you're in the locomotive, it works fine.
However, the Call Shuttle button is apparently coded to specifically look for entities with name = "shuttleTrain" which means it only works with the included locomotive (gives a "no unused shuttle" error if none are present).

I can't figure out how to add other locomotives to the variable if they have the module (as I'm no coder), so maybe the author could chime in?
