LEGO  

I am so excited to Run it on my layout

They've done that (selling the electronics separately) for several trains over the past decade (EN, HE, Crocodile, etc), but I don't think it's helped the sales... everything LEGO has done for trains since the 90s suggests that trains in a vocal minority at least as far as profits is concerned, but without seeing their actual numbers everything is indeed hypothesis.

Hi, Rebrickable is only for selling instructions, not kits. You'll have to supply your own parts.

@@NonsenseWars Makes enough sense, thanks for letting me know. (=

Not 100% about the ML (#8 right?) wheels... there's some greebles under the chassis and on the drawbar (like the brake shoes and the steps) that might scrape, but they are also not structurally important and could probably be removed. For sure the coupler heights would be a bit off without any adjustment though.

@@NonsenseWars Alright thanks! Guess I will find out when building :) Apparently ML/#8 is 1 plate less in diameter than L, which means the chassis will be half a plate lower. Might be tough to get the coupler up half a plate but it might not even be necessary Keep up the awesome work!
