Today's city buses were built on standard chassis of automotive commercial vehicle manufacturers, they were meant for carrying goods and other applications. Hence city roads are occupied with bulky and space occupying structures. Quite often they might be plying with less than 50% occupancy. Besides polluting.

The ideal City Bus should be smaller, carry the same load of large bus, fuel efficient, flexible and easily manageable.

I come out with an idea of building a bus made up of 2 carriages, they are attachable and detachable.

Please review the illustrations which are self explanatory.
