Abstract
The life of human in the 21st century is facing a new facet by its virtue of speed and fast involved in their day to day life. Migration becoming the common in their lives and unavoidable to meet the new challenges of the life. The result is that travelling becomes part of the life. The Rail transportation is the only existing feasible economic and speedy media suitable for all economic classes in the Developing countries. Last but not least the railways are the widely accepted transportation for the goods and materials. In India Freight traffic volume has risen by 620% and passenger traffic by 514% since 1951. They carry more than a million tonne of freight traffic and about 14 million passengers covering 6,856 number of stations daily. This rapid rate of increase in number of train passengers and freight traffic in the developing countries like India is quite an example of the importance of the ‘Rail’ as media of transportation in the human community.

Rail Disasters- An over view
The advancement in the technology changing the rail transportation scenario by introducing the super fast trains with the high standard of safety to meet the needs of community. The other facet of the scenario is that the risk for life in rail travel is increasing due to the frequent occurrence of train accidents. India's massive rail network is hit by an average of 300 accidents a year. The train disasters are spatial events happening as a result of range of factors like human error, antiquated communication and safety equipment, signaling systems, ageing bridges and tracks, increase in passenger and freight traffic and sometimes natural calamities have led to rail accidents. Out of these range of factors most of them can be avoided by the proper planning and implementation of systematic approach with the utilisation of latest developments in the GIS and GPS technology. The rescue operations can be effectively implemented with the aid of GIS as Disaster management tool.

GIS & GPS Integrated approach
The GIS approach in rail disaster management can play two different roles to minimise the effects of the Disasters. The implementation of integrated GIS & GPS technology to improve the siganalling system and to monitor the rail traffic on real time basis by installing the advanced GPS equipment in the trains to minimise the human error in the system. The latest GPS equipment available in the marked will give the positional accuracy of 2m can be utilised to monitor the traffic at the suspected area like signalling cabins Junction stations and signal bifurcation.

This positional accuracy may not be sufficient to locate the exact position of the train on particular track but can be utilised as the real time input to the system as cross checking measure to ensure proper siganalling.

The rescue operations after such an un-fateful disaster can be planned and implemented by using the GIS advantages. The Emergency disaster management requires locating the exact spot, incident mapping, identifying resources, establishing priorities, developing action plans, and implementing the plan to protect lives and property. Time will play crucial role in disaster management activities. The effective planning can began only after identifying the exact location of the incident, accessibility information, and resources available. The GIS can be used as spatial database to provide the necessary information require for rescue planning with in the least possible time frame. GIS allows disaster managers to quickly access and visually display critical information by location. This information facilitates the development of action plans that are printed or transmitted to disaster response personnel for the coordination and implementation of emergency efforts. GIS also allows continuous monitoring of the rescue activity and dynamic changing in the strategy to minimise the effect of disaster by identifying and alarming the required equipment and personnel required to manage the disaster.

Conclusion
GIS is essential to effective preparedness, communication, and training tool for disaster management. Integrated GIS & GPS technology is most essential element to improve the preventive measures for rail disasters.
