New device to prevent collision of trains now

NEW DELHI : Accidents caused by two trains running on the same track can be prevented through a light depending resistor instrument that will automatically slow them down to avoid the crash.

The gadget has been developed by budding scientist Utkarsh Sharma of Mathura who is just 14, studying in class VIII. It consists of LED lights fixed on the front and back of the electric train, with a light-dependent resistor that gets activated to cut off power to the two trains and they automatically slow down.
He is among 35 young students selected in a national competition to present their projects at the National Level Exhibition and Project Competition that has been organised here since 2008 by the Ministry of Science and Technology.
The exhibition thrown open to public for two days from Tuesday also has another innovation by Ayush Khanna, a class X student from Ludhiana for reducing road accidents and automatically charging car batteries.
It involves construction of solar power-based roads with three layers of base plate, then power generating plate with micro-processor sensors and the top an ordinary layer.
Sunlight will produce electricity under this road while the induction system will automatically charge the batteries of the vehicles plying on the road.
Khanna’s project also has a control room that will monitor every vehicle as soon as it comes on this road and the microprocessor sensors will automatically send signals to the control room if two vehicles come close to alert their drivers to avoid accident.
