The Station66 is a Trainstation Monument with 3 Cards you can use.
The Doors are blocked to get into the Trainstation. To Unlock them, drive with your Train into the second Raillines and Destroy the Barricades. A Sensor will open the Doors to the First Puzzle after moving into the Sensor.
For the first part you need Fuel, a Fuse and a Bluecard to get access to the Elevator and the Top Room.
The Top Room needs 4 timer to activate before using the Redcard to get into the Loot Room.
Also on the Topfloor, is a small Greencard room. Its not needed for the Redcar Puzzle but can be taken as + Loot.
