Coke Wagons at Shenston Road - Greg Brookes
*****************************************************************************************************************************************************************
Later in life, some of the earlier wagons which were built with steel raves, had these replaced
with wooden ones. The process of loading the wagons with hot coke, made for a very corrosive environment and the
original paintwork didn't last very long. Many wagons could be seen in the late 60s and early 70s with patched up
bodysides. This view shows an early body style wagon with replacement wooden raves.
The area behind the bufferbeam on the kit requires plating over as per the prototype, using 20
thou' plasticard, and this gives additional strength to the wagon and covers the 'see-through' appearance. After
fitting the 3 link couplings, I have infilled the area under the plate with Araldite, which bonds the coupling
tails, the bufferbeam, and the hopper body together.
The mid body design of coke hopper (BR diagram 1/151), were built between 1951 and 1958 at BR
Shildon and numbered B447500 - B448949. The conversion to this style of wagon is easy, by replacing the hopper
ends with pieces of 40 thou' plasticard. The stanchions are made from 1/16th" Plastruct 'T' section, chamfered
at the top, and at the bottom where they join the bufferbeam.
To represent the worn out look, the wagons are painted in various colours, and it takes quite
some time before things start to look realistic - usually waiting a couple of days before adding another layer
of different coloured paint.
The final design of coke hopper had solid sides and ends (BR diagram 1/152), built at BR Shildon
in 1958 and numbered B449200 - B449299. To produce this variant I scratchbuilt the bodies from 40 thou' plasticard
and mounted them on the existing hopper bases after removal of all rivet detail.
This view shows 2 of the final design coke hoppers under construction. An unusual aproach on this
batch of wagons was to load and secure the coke in the hopper before construction had finished. This was done to
stablise the fragile bodies, and a good test for the security of the coke load. If it can be handled frequently on
the workbench, it should be permanant enough for future use.
With some part started Parkside 21t hoppers in the background, 4 HCO 'tubs' can be seen after
initial weathering. The chassis need modifying to the later BR standard roller bearing axle boxes, obtained from 51L / MSE.
In addition to the 4 'tubs', another 7 mid body design hoppers creeped onto the work bench so I
could get uniformity with the loads. With 11 coke wagons on the bench, certain tasks become tedious, so it was a
case of splitting the project and concentrating on smaller batches.
Still with some finishing work to be done, some of the hoppers are seen here on running tests.
Almost nearing completion, a later body style wagon can be seen here with roller bearing axleboxes.
As with all wagon projects, reference material is very important, and I have found Paul Bartletts
wagon website invaluable, with thousands of colour photographs of hundreds of different wagon types.
44005 heads through Wibdenshaw with a long rake of coke hoppers, the various styles being mixed together.
An article appeared in the 'Model Railway Constructor' (Aug 1983) outlining the history and details of
the coke hoppers, and includes some photographs and drawings of the different types.
The TOPS code given to the majority of coke hoppers was HCO, and a few of the mid body style wagons
received through vacuum pipes making them HCP. Most wagons ended their lives still branded COKE or COKEHOP. One later
style hopper received vacuum braking (HCV), and was used with unfitted hoppers on the Pensnett circuit.
This wagon just requires some final weathering to the chassis, and at June 2008 was the 17th wagon in the rake.
The last 5 wagons entered the Wibdenshaw fleet in early 2009. They were purchased as 'kit built' early
body style, dismantled and new bodies scratchbuilt in the same way as mentioned above. They are seen here on running tests.
Balsawood formers are fitted into the hopper body, to allow the load to be fitted, which
consists of crushed coal soaked with diluted PVA glue, then painted and washed to look like coke.
This view shows one of the wagons nearing completion, the body having been painted and
weathered. Just a few finishing touches and number panel to be added.
A Brush type 4 waits in the down goods loop at Shenston Road with a rake of empty coke hoppers
returning from Pensnett to Llantrisant. It was more common to find the diesel brake tender behind the locomotive
during this period, as forward visibility from certain clsses (Peaks & class 37s) made 'SPADS' more likely when
stopping at signals.
The Pensnett branded coke wagons had deeper chutes under the hoppers, and were easily identified by
the markings painted on the wagon sides.
In the 1970s these wagons were formed into TOPS pool 7071, made up from the later design of hopper
body with no raves.
The one and only vacuum braked example.... it must have been a bit of a squeeze getting to
the brake cylinder!
