Flexible track (often referred to as flex track or flexi track), as its name implies, can be bent to any shape you want. Model railroaders can usually purchase it in three-foot lengths.

Flexible train track has the advantage of being bendable which opens up new options when planning a model train set layout.

Flexible track can be curved or laid straight or any combination you wish. With flexible train track there are usually fewer connections to worry about.

Flexible train track does however need to be nailed down to a board and the rails need to be trimmed to length as you bend the model train track.
