I have no Hornby Dublo models just saw the latest model rail mag and wondered what purpose the centre rail had if the outer rails covered the circuit of electricity.

Well in real electric trains like subways .. the center rail supplies the current on which it runs . maybe it is just for looks if does not supply the power to run your model.
