Smallish train with a weird gimmick (SGTOOLS + LVL3)

Hi everyone, has been some time since I last created a chain, which can be observed in the missed deadline in one of the wagons, oh well. I also included a fun twist midway, hope you like.
Also, story time, I broke my elbow last week, it sucks, but I can adapt too, like that new meme says (I actually have the same set up on my left arm haha).
Short story hm, so I guess, bottoms up for them broken bokes yah? Cheers.
