My first (belated Halloween) train

Hi everyone.

This is my first train. I'd planned to make it for Halloween, since it's a zombies and aliens train, but I just couldn't find the time.

So here it is, a week late. It's only a bundle, made of six carriages and an easy puzzle at the end, but I had fun making it anyway. I hope you have fun on the short journey

Good luck, and enjoy. :)

(I wasn't sure where to put this. Trains seem to go in Puzzles, General, and Off-topic. So I just chose General.)
