TDMS is an Android application developed by the Centre for Railway Information Systems and is designed exclusively for the internal use of Indian Railways.

With TDMS, railway personnel can easily track the movement of patrolmen and important equipment known as OHE assets. It uses GPS technology to provide real-time updates on their locations, so managers can keep an eye on everything that's happening.

One of the key features of TDMS is its ability to capture and report any defects found in the OHE equipment. Patrolmen can use the app to quickly document issues they come across, take photos if necessary, and create detailed reports. This ensures that problems are dealt with promptly and efficiently. TDMS also sends alerts and notifications to depot in-charges and officers through SMS messages.

So, with TDMS, Indian Railways can ensure smoother operations, quicker response times to defects, and better decision-making for a more efficient railway system.
