Short train for short-term employment [ended, solution posted].

As the Halloween hype is over now I wanted to find a moment to thank everyone who supported me on a recent unemployment train.
That one is over as I got a casual position in academia for at least the next few months, so I'm feeling a bit more secure and I got back to solving puzzles again, yay!!!.
Haven't got any paychecks yet, so don't expect a train of grat value: mostly bundle leftovers and simple unbundled games.

Commenting not necessary. Comment if you have something smart/funny/encouraging/insulting to say.

• The train is Level 2+.
• Puzzle included. Should be easy cause excessive amounts of rage.
• Post-puzzle non-bundled game is without level restrictions.
• Hints will be gradually provided.
• Special whitelist giveaway available
• First 3 non-whitelisted users to comment in a hidden giveaway will be whitelisted.
• No hints/no link sharing, thank you.

GO!

Congratulations to the winners and to two new whitelist entrants. Gifts have been/are being sent.
