Forgotten Cake Day/Week Train and Almost Level 7 Celebration [All gone!]

As is now a proud tradition, I missed my Cakeday this week. In fact, I would have completely missed it, were it not for the lovely messages.
My excuse, and I think it's a good one, is that my Steamniversary is in November and I always confuse the two.

Anyway, I have spent some of my free time this week putting together a half-assed train, instead of playing Portal Knights (you're welcome) and with that magnificent introduction, I bet you can't wait to board.

There are 24 carts, bundled and unbundled (no Bad Rats but just don't expect Cyberpunk).
No 🤖 allowed, for security reasons, so there is a extreme massively super hard puzzle to solve first, as I have not yet learned how to use sgtools.
If you get stumped, just ask for more hints but there are several answers so you should be fine.

No big questionnaire this year, but there are some random factoids from Fluffypedia so feel free to share yours, or pictures of your pets or whatever you want.

Also looks like this little train might take me over to Level 7 (if nothing shifts to the free/bundled list) so what the hell, let's celebrate that too!
I added quite a few of people to my White list and there is a little special giveaway coming for my blue hearts, straight off the 💙 wishlist so keep your eyes peeled.

Thank you all for the great community, for your generosity and your support to strangers who wander through here, and for going round and round with me while we debate about important and unimportant issues throughout the year.

Oh and obligatory poll, in which I may have decided to alienate as many gamers as possible.

Have some cake and all aboard! 🎂🎫

Tickets please
