Introduction:
The Indian railways is the very important with respect to its huge and large passengers communication mode as well as transportation of goods.Day by day the number of passengers and goods carriage is increasing such a manner that more numbers of trains are continuously being incorporated. But the major problem is that the number of railway tracks are limited. Within this limited number of tracks it is going day by day so much intense to control the traffic. The major problem raised as the number of railway accidents are taking place than the previous time. There exist TPWS and ACD to combat with these problem but that it looks it is not sufficient enough to combat with this problem. So research work is going on with this issue. This following discussion presents the improvements by the use of RFID, FLIR camera and other embedded system along with the existing system to give the more reliable method to stop railway accidents as much as possible.

EXISTING PROTECTION SYSTEMS:
Presently the Indian railways are using TPWS system where if two trains remains in the same track then the system automatically applies brake but it does not give any further information whether there is any obstacle present or not that can cause accidents. Though these conditions should be known to the driver to make him aware of these conditions. Anti-collision device are also at presently are in use. This system makes use of embedded controls and a GPS system thereby preventing collision between trains and tries to prevent accidents.
The issue is these existing systems that uses ACD & TPWS do not take care of the environmental factors and other several factor like bridge problem, obstacles in the track, missing of railway tracks.So some improvements are needed also in these cases. So RFID (Radio frequency identification) and FLIR camera are being incorporated

OVERVIEW:
The overall system is going to be demonstrated to protect railway accidents. The central system performs all the major tasks. The RFID reader reads the information using the RFID tag attached to other trains and all the locations throughout the track periodically. The IR camera send the image information of a particular location...
