1) The document proposes a system for a smart driverless railway engine that uses sensors and wireless technology to enable automatic control of trains.
2) The system aims to prevent railway accidents by allowing for automatic station detection, signaling, track cut detection and mapping train positions. It also enables automatic gate control to reduce human errors.
3) The system is intended to make rail operations independent and automated by allowing for control of trains from a central server using an RF wireless network. The server would monitor train positions and issues and stop trains before any accidents occur.
