A turnout serves to switch train from one line to another. The turnout consists of a Point which is switchs the rail to induce direction and a Crossing which is cross over two line on the plane surface and a Lead where is middle section in Point to Crossing. Point machine consists of a turnout is important facilities in railway signal that is safety issue relates in derailment of the train. Recently train delay and accident frequently occurred because of the turnout include in a point machine trouble of electrical and mechanical. So in order to prevent train accident the research is advanced install of normal and reverse indication lamp in a point machine development of adherence detector for sensing the status of adhesion between the stock rails and tongue rails etc. In this paper investigates the problem which is connected with a turnout trouble include in a point machine occurrence at the time of train accident and then proposed to the safety system model in order to prevent the train accident in turnout.

For the characteristic of improvement of railway roadbed environment and a convenient maintenance the use at ferroconcrete roadbed is increasing. The ferroconcrete roadbed arranges the steel frame with the lattice shape and submerge of a concrete. In order to overcome the limit of ground signal system, the use of AF track circuit for CAB signal system is increasing. The AF track circuit using on audio frequency signal is being influence with ferroconcrete roadbed. It occur to alternation on the track circuit characteristic. This paper prove influence of the AF signal and ferroconcrete roadbed by simulation and then calculation of distance variation of track circuit.

In this paper, the method is suggested to prevent data collision or damage on RFID(Radio Frequency Identification) system, in case a reader reading multi-tag simultaneously, using binary-search algorithm and Time-domain anti-collision procedure at reader and tag, respectively. The RFID system is designed that Reader enable to communicate with Tag on 13.56MHz bandwidth which is ISM(Industrial Science Medical) bandwidth, antennas of Tag part are designed using MCRF335 Chip. When RF communication is achieved between reader and tag, in case that data is transmitted to reader pass through multiple tags simultaneously, a study on the anti-collision method for the situation that the data collision occurs is performed.
