Question

how does using train as a transport(compared to the use of bus)conserve more fuel?

Answer 1

Because more number of people can be accomodated in a train as compared to buses.....so a train will conserve more fuel because only in one ride it delivers many people to various places.

Answer 2

a train uses more fuel than a bus but it is more profitable because a train has a number of coaches and each coach has a number of seats but bus has a very few seats compared to a train so a train makes more profit than a bus.
