Catch-up train. Part I

I've fallen behind with my sent/received giveaways ratio severely so this an attempt to catch up a bit if not with quality but at least with quantity. All gibs are level 3.

Train

trainz are abcdef

I'd appreciate if instead of "thanks" you leave some funny memes/videos/etc.

EDIT: A solution as some people struggled to solve: it's a simple substitution cipher, "trainz are abcdef" is a key, each letter of "trainz" should be replaced with its counterpart from "abcdef" in the SGTool identifier (971f2ti3-in55-4aa2-9564-8020365a2rrz)
If you're replacing the letters in a text editor you should be careful around "a" letter since it's present in both sets.
