Introduction

This paper briefly explains the formation of a simple railway line control system as well as relationships between its subsystems. A simple railway line control system is formed by switch boxes along the track as well as the on board train control computer, while a simple railway line means a single track branches into two separate tracks for trains to pass each other, then immediately joins together. (Figure 1) The main control system consists of three subsystems which include safety, control as well as interlocking system. A real life example of a simple railway line can be found in North of Denmark (from Hillerod to Tisvildeleje) which is a privately owned railway with low traffic density.
