The concept is simple. Z-Bend Track uses a double track mainline running down both sides of a module. Modules can be of any length, or width in the middle and any overall shape you desire.The "standard" called Z-Bend Track only applies to the last five inches (12.7 cm) of the module’s interface to other modules, the electrical interface and the module height. There are very, very few "rules" for the rest of the module.
