Why do buses have rear engines?

When loaded, buses get traction thanks to being rear wheel drive.

This will ensure that the back wheels and engine are connected.

Power loss and an increase in weight are the result of having to put in a transmission shaft.

A rear engine prevents this and is better overall for the bus.
