I am wondering if he is confusing 4 foot with 6 foot.Why would be there third rail inside the four foot?
I'm still not 100% on what you are saying. Do you mean that Merseyrail has third rail on an up and down running line for example. But where there is a crossover there isn't third rail and they coast over it?
Just to clarify - double track railways have a cess on the left. The "fourfoot" is the gap between the running rails and the "sixfoot" is the gap between one track and the other.
BR 3rd rail has a third rail alternately on the cess side and the six foot side.
The London underground has fourth rail DC which has the 4th rail placed between the two running rails and therefore within the "fourfoot"
