Road-rail vehicles to protect railway

I was saddened to see the recent violence against innocent people and destructive activities on railway. The government should take immediate steps to enhance the security of railway passengers and protect railway properties. A very simple scientific, engineering plan can solve this. This can be done with minimum amount of time and cost.
A truck/jeep or similar motor vehicle should be converted into “road-rail vehicles” by mounting them 'on two sets of rail wheels and a transformed chassis. Rail wheels from “CJ type goods-carriage” can be used. The transformed road-rail vehicles can be driven on the rail-tracks at a speed of 45-50 miles/hour. The trucks can be used to check the status of railway tracks and related systems. The railway police officers will be able to ride these vehicles to check the railroad track several minutes before a train passes the track. Engineers from BUET, similar universities or Bangladesh Railway's workshops can help to design and produce such vehicles in large quantities.
