BR had 4 pairs of Girder WG which were all diagram 2/150. When unloaded they were connected together by a semi-permanent bar coupling. However, when loaded they were seperated by the load. All of them were employed carrying replacement girders for the North London Line as it bridged the Midland Main line. Genesis make a 4mm kit.
