Automatic rail traffic control system for bi-directional sections

Abstract

This paper explains an automatic rail traffic control system for bi-directional sections and provides a complete train control solution for single line sections. The block and block stations in the sections are interconnected, which enables the block station to automatically change its parameters of operation, according to the movement of trains in the block. The system classifies the status of the section into three broad categories, viz. single train movement in the adjacent block sections, offensive train movement in the adjacent block sections and back to back train movement in the adjacent block sections. The control algorithm for each category is unique and the operational parameters are according to the existing system of control. An optional manual control panel, which is of a centralized traffic control (CTC) type, is also included in the proposed system.
