So 2 updates. First, some are reporting that multiple people in NZ got the train instead of the castle, but it may just be the same pics going around.
Second, the guy posted an update and there is no surprise box like in Diagon Alley. Also the 8x16 UCS tile is a sticker not a print as reported by promo bricks.
New update: My wife returned from her work and opened the box without telling me! Now there's no going back... Soooooo, new photos of the contents are uploaded to the link.
A. It consists of 45 plastic bags + 2 no numbered bags. 19~45 can be found right away when you open the box, but 1~19 + 2 extra bags + instruction manuals + stickers are in a white smaller box inside. B. It has 4 sets of instruction manuals.
1 - engine room
2 - cargo
3 - passenger carriage
4 - platform
C. Sticker photo is attached
I'll start assembling but most likely I won't be able to finish the build today. I'll keep you guys updated tomorrow, too!
