Another candidate that reused the same steel underframe design was the Dia. 6C 3-Plank Open Wagon. Much like the 6-plank equivalents, these were general-purpose wagons with a 10-ton load capacity.

The GCR built these for both their own use and on behalf of the CLC. They featured dropside doors on both sides, GCR lifting link brakes and ribbed buffers.

Of the 50 originally built for the CLC in 1919, 49 of them survived until 1930, when they were split between the LNER and LMS using the same method as the Dia. 17B Covered Vans. They joined the surviving GCR versions that had already moved to LNER ownership as part of the grouping, but there are scant details of their lives after this date.
