One of the little Gremlins that surfaced when testing Tredethy Wharf was the in continuous check rail area where a road will cross the track. For some reason I purchased S4 plastic check rail chairs instead of P4 which caused some slight wheel binding on a converted Pannier Tank in this section of track.
As all of this section will be fully covered I decided to try and solve the problem by relaying this section using copperclad sleepers. A sharp knife blade was slid between the plastic chairs and the wooden sleeper and the rail removed. Copperclad sleepers were then laid between the wooden sleepers. The rail was cleaned and then relayed with some very crude soldering. Some advice I'd been given was, as this section is to be covered, to double gap the copperclad sleepers as a 'belt and braces' against electrical shorts.
After a brief test I think I've sorted it... Should have laid this section in copperclad from the start.
