The Halloween event is now live! You'll find Neuschwanstein Castle and The Liberator have dressed up to celebrate and can get Halloween Gift Presents as drops throughout. It will be available until the next update on the 3rd.
On Russia you'll now find a driveable train on the main line! It's the new fastest way to travel in the game - as long as your destination is along the tracks anyway. The goal is to sort out any issues with the train features this week and then in the coming updates to add support for multiple attached train cars (I'm thinking flatbeds so you can build huge bases on the train!) as well as bring them to the other maps.
