The CPP which washed and blended the coal prior to the coking process stood at the north-eastern end of the site, along with large storage bunkers.

The ovens themselves were parallel to the A694, which passes the site, and stood on the area of land now occupied by the two football pitches.

The latter "scrubbed" the gas produced in the ovens, extracting chemicals such as tar and ammonia, which were piped into storage tanks.

There was a motive power depot nearby to house the locomotives which shunted the extensive network of NCB sidings and lines which served the works and the lower part of the Derwent valley.

7 and 59 were two such locomotives, easily identifiable as former NCB Lambton system residents from Philadelphia shed by their narrow curved cabs which allowed them to negotiate a tunnel with very limited clearances on the line to the docks at Sunderland.

[1] Very little evidence of the plant remains, however, the large stone wall separating the railway line (now a public bridleway) from the A694 where it ran along a narrow ledge between the river and the road is still in situ, as is the bridge on the A1 Western By-pass, under which the line ran to the BR exchange sidings and the staithe.

Some of the rolling stock has survived, with at least one hopper wagon marked NCB D/HAUGH residing on the Tanfield Railway, along with a Consett Iron Co. van which for many years served as part of Derwenthaugh MPD's breakdown train and a tar wagon originating from Bankfoot Coke Works (near Crook) which had found its way to Derwenthaugh by the time the works closed.

The Kitson pannier tank was also rescued from the cutter's torch in 1972, and in 1986 was restored to its original identity as Consett Iron Co. "A" class No.5, and repainted in the Indian red livery it carried when new.

The stone abutments of a bridge on this line can also be seen to the rear of the Golden Lion pub, and the style of construction (yellow pit-bricks and tall arched windows) of the house immediately adjacent to this pub suggests that it was part of the mine complex, but it was in fact a Primitive Methodist Chapel, built circa 1869.

[3] After Derwenthaugh closed, Monkton near Hebburn was the only remaining coke works in the area, Lambton, Norwood and Hawthorn all having closed a couple of years previously (the latter was the newest works, opened to process coal from the massive Hawthorn Combined Mine in 1961, but was mothballed during the 1984–85 miners' strike and never re-opened).
