I have recently started getting back into Lego after a long hiatus (i last used them when i was 13), and have really gotten into trains and want to use my EV3 to build one. However, I am finding almost nothing online and admittedly, I am not the best at building stuff myself (might get better over time tho). Do any of you guys have any ideas, builds, or any advice even for me to first build a train and when doing so, fit the big brick in a way that is sleek?
