A Rail is used for building a railway track for trains. Unlike transport belts, rail tracks can also be curved and placed diagonally. Train stops, rail signals and rail chain signals can be placed on rails to better guide automated trains. Gates can also be placed on rails, making them rail gates. In Space Age, rails can be connected to rail ramps and rail supports to build elevated rails. Elevated rails allow trains to freely pass over obstacles.
The minimum rail turning radius is 13, meaning the smallest possible 180° turn has 26 tiles between the centers of opposite rails. However, due to rails being two tiles wide, the actual footprint is 28 tiles wide.
The rail planner can be used to automatically place rails. See the page for more info.
