Are they "chunky" enough to carry the sort of currents that can exist on a DCC layout with multiple locomotives in operation? They are a nice idea if they are.

Put a piece of thin card or plasticard hard against the inside of the running rail until the polyfilla has dried? You may need to coat the outside of the card with something to prevent the polyfilla sticking - maybe sticky tape?

You will need to be sure that the polyfilla in the centre is no wider than the minimum back to back wheel measurement of the locos and wagons you are running.
