Would it be possible for something like this to be added? Maybe the locomotive would be a tug boat that pushes/pulls. An in-between that can fit in narrower lakes, is a little faster, but the wagons/barges have less capacity than a ship. I really like the idea of a sort of train on the water. I think the image above is from someone else's mod that got discontinued a long time ago. Here's the mod page if you want to check it out https://forums.factorio.com/viewtopic.php?t=13953
Additionally, I saw that older comments in the Discussion section used 💡, ✔ or ❗. Is that something everyone did on their own or do you add that once something is resolved/finished?
