1. Railway anticollision apparatus comprising:
- a plurality of optically machine readable trackside markers positioned at preselected trackside positions and providing as trackside marker information a track location position;
optical means positioned within a given train for reading a given trackside marker; and
communication means carried by each train for transmitting and receiving between trains the respective trackside marker information and processing the same to provide an indication of a potential collision.

Abstract
A railway anticollision apparatus and method is disclosed in which machine readable trackside markers such as bar code markers are utilized along the track and are read by apparatus on board the train to provide track number identification, milepost identification and train direction. On board the train is equipment to provide train identification and train speed. This information is transmitted through transponders between trains and to a central station and is processed by apparatus on board the respective trains and the central location to provide visual and audible signals indicative of a potential train collision.

6. The method of preventing railway collisions comprising:
-
placing at preselected positions along the track side, optical machine reading trackside markers providing the information of track direction, track position and track identification; reading the machine readable trackside markers by optical machine readable devices positioned upon a given train; generating a train speed indication signal; generating a train identification signal; communicating between respective trains within a prescribed proximity the information of track identification, track position, track direction, train speed and train identification; and processing the communicated information upon each respective train to provide indications of a potential collision situation.
