Sadly no progress have been made on the locomotive, haven't really had any motivation to play Stormworks for a while.

I do wanna say that the coaches were initially intended to just be their own standalone thing without a matching locomotive. First came the basic coaches, later came a control car. It was only after I made the control car I decided to try using the cab for a locomotive again.

So I encourage you to use whatever TCP locomotives you want with the coaches, there's many options in the TCP collection, which is linked in the description.

Just wondering if there is still any chance of the locomotive being released, love these coaches but it pains me to put them with the wrong locomotive

What locomotive? There's no locomotive in this collecion!

How do i even start the engines ,the Request Master button and the Remote engine start button doesn't even do anything, the Engine is stuck at 0 RPS, and ive looked around the entire locomotive, even the W.C, and anything, i didnt even find a switch to turn it on.

The locomotive will be published as well.
It's not quite finished yet, and it's hard to say when it will be out.
Though remember all TCP locomotives will function wtih these locomotives, even if it's not a visual match.

Will the locomotive in the picture be published? I can't find any other locomotive that matches the wagons visually
