Hello!
Since I started using here, almost one year has passed.
The cake day has approaching!

I make Double-decker train with 100+ GAs!

Ride Here almost all LV 2+

This is my first train and puzzle.
I can make only 56 GAs,so I need friends' help..

Special Thanks for Volteren2980 and steamgiftjohnny!

Model of this train is E4-MAX,
Double-decker bullet train.(That called Shinkansen in Japanese)
MAX means initials of "Multi Amenity Express".
Thats great train!

With each Upper Deck,there are some good things and non-bundled game.
Solve puzzles to enter upper deck.

GOOD LUCK!

Hint for beginners added on N5-8.
