Global Navigation Satellite Navigation System (GNSS) is widely used for surveying, navigation, timing, positioning and Tracking. This is a technique which is highly precise, real time, continuous and work in all weather conditions for providing position and navigation information. Two GNSS systems are currently fully operational, United States GPS and Russian GLONASS. GNSS is used in transportation industry for monitoring various types of vehicles like, aircrafts, ships, trains, buses etc. In the industrial and public transportation, railway is widely used by people in the world. Monitoring the trains is concern with the security and safety. In this paper, a GNSS based web application is proposed for monitoring trains. GNSS provide navigation and positioning information of a train. This web application is developed in C#.net using Microsoft Visual Studio 2010.

Now a days managing train movement between stations in railways has become staggering task which involve human efforts like data transfer through phone. It is needed to be continuously monitor the trains approaching from neighboring stations, for safe train movement due to high density of trains on a track. Conventionally, station master monitor approaching /departing trains by using Route Relay Interlocking (RRI) system which can monitor trains between station blocks. In this paper a GIS augmented automatic train monitoring (GAATM) system is proposed for station master to monitor approaching/departing trains to/from station. If station master has interest in a specific train, He/she can search and monitor that train in real time. The proposed system is developed in C# and java script using Microsoft Visual Studio 2010.
