RailFans don't miss their train. Why? Because they go to the station HOURS before the actual departure of their Train - to watch OTHER trains depart. - Prince Maan

Hmm...but i think coupling can prevent rest of coaches from derailing ...And derailment will not take any lives...at the most there can be some minor injuries ...people lose their lives only when coaches topple and climb over each other...hence lhb should be introduced in each train...
