Anti-collision Device (ACD) branded as “Raksha Kavach” developed by Konkan Railways has been successfully granted patents by China, Russia, Singapore and South Africa. Konkan Railways has filed patent application in 124 countries.
Raksha Kavach is a self-acting device that warns the train driver of any impending accident-like situation within a 3-km range.The instrument will cost approximately Rs 5 lakh (500,000) for installation in trains and Rs 10 lakh (INR 1000,000) in planes. It has already applied for international patent rights for the product in 124 countries.
Sky Bus, an alternative of metro railways for urban transport, is also innovative solution.
My experience with Konkan railways was superb particularly in term of cusine.
