Fisherton Sarum

H16 class 4-6-2T tank No. 519, built from a Falcon Brass kit is turned at Fisherton Sarum. She must have been borrowed on a freight turn from Feltham. N1 class 1822 passes by on a ballast train in the background.

As I mentioned in my Talking Stock #26 post here about the four Urie G16 class 4-8-0T locomotives, I do indeed have a soft spot for large tanks and therefore this post is about Urie’s other large tanks the five H16 4-6-2Ts. The later Maunsell Z class 0-8-0T locomotives  were the subject of Talking Stock #19 post here, whilst Maunsell’s W class 2-6-4 tanks will soon also feature on this blog.

The ex London and Southern Western (LSWR) Urie H16 class of 4-6-2 tanks were introduced in 1921, and if you have read my Talking Stock #26 post, you will know already that this was the same year as their slightly smaller sisters the G16 4-8-0T class. The two classes sharing many common parts such as motion, bogies, boilers and fireboxes.

Both classes were built in association with the new hump marshalling yard at Feltham. Rather than the four G16s which were designed for working in the confines of Feltham yard the five  H16s were intended for cross regional goods traffic between Feltham and the North London yards of Brent (Midland) and Willesden (London North Western). For this duty they had  5’7″  driving wheels, larger than the G16s, larger water capacity and the extra large bunker was carried by a radial truck.   As they were also used occasionally on empty carriage stock working between Waterloo and Clapham Junction and on special passenger trains, such as during Ascot Race Week,  the H16s were initially given the standard Southern passenger livery of lined olive green unlike the black livery of the G16s, giving rise to their nickname amongst operating staff as ‘Green Tanks’. This changed to a plain black livery, in common with all Southern locomotives from 1940 due to watime constraints, and was retained during BR days until their withdrawal in 1962.

H16 number 519 viewed from the other side and shows off the powerfull looking nature of these tanks that appeals so much.

My model was built, with much effort, from a Jidenco etched brass kit; that owing to the quality of the kit design, thin etches and limited instructions, took a number of years of starting, doing a bit, getting frustrated and putting down again before finally getting round to finishing.  Certainly not a kit for the feint hearted. She is powered using a Portescap coreless motor along with quite a bit of lead weight added to provide adequate traction due to the lightweight thin etched brass construction of the kit with only the small dome, safety valves and chimney being white metal castings.

My usual excuse for an occasional appearance on Fisherton Sarum of an H16, as they were only allocated to Feltham, is on a running in turn from Eastleigh although that does not really explain her weathered condition, so perhaps she was borrowed for a freight trip down the West of England line?

I have a bit of a soft spot for all large tank locomotives and a number of classes of large tanks existed on the Southern Railway such as the H16 4-6-2T, W 2-6-4T, the Z class 0-8-0T that I featured in my Talking Stock# 19 post here and the topic of this post the G16 4-8-0T. The H16 and W classes will I am sure be the subject of future posts.

G16 494_1

A Urie G16 class number 494 from a class of four locomotives

The ex London and Southern Western (LSWR) Urie G16 class of four 4-8-0tanks were introduced in 1921, the same year as the larger H16 4-6-2T. The two classes shared many common parts such as boilers and fireboxes.
Having eight-coupled wheels of 5′ 1″ diameter, they were clearly intended mainly for hump shunting duties at Feltham yard and spent most of their lives to the shed there. Weighing in at 95 tons they were certainly heavy tanks and with a Tractive Effort of 34,000 were the most powerful locomotives on the LSWR. In common with the T14 4-6-0 ‘Paddleboxes’ and H16 class were the widest steam locomotives in Britain.
At one stage Maunsell was considering building more G16 class locomotives, as only four were originally built, but instead opted for his Z class 0-8-0T. With the introduction of the 0-6-0 diesel shunters in the 1950’s one was withdrawn in 1959, another in 1960 and the final two in December 1962.

My model of 494 is built from a Golden Arrow Productions resin body kit

My model of the G16 makes the odd occasional appearance on Fisherton Sarum which must be a running in turn from Eastleigh works, as Salisbury would have been a bit far for a trip working! It has been constructed from a Golden Arrow Products resin kit mounted on a modified Hornby 8F chassis. This is somewhat of a compromise as the G16s had an evenly spaced 5’1″ driving wheels on 6′ centres whereas the 8F has 4’8″ drivers on unequal spacing. The kit correctly requires the cylinders and valve gear to be relocated further forward and the cylinders inclined. The main connecting rod is therefore relocated to be driven off the second rather than the third axle, this in itself creates another compromise as the large balance weight remaining on the third wheel set is incorrect and not easily rectified (it is not possible to simply swap the second and third wheel sets over as the chassis is driven via the third axle which therefore has the driving gear mounted on it).

As the kit only comprising of the resin body and chassis extension components for the detail items I used: Alan Gibson turned brass handrail knobs; Craftsman Models white metal Drummond style buffers and Urie whistle; brass clack valves, smoke box dart, etched rear spectacle protection bars and injectors from Mainly Trains; various pieces of copper wire for pipe work, plastic section for the bunker rear steps and lamp irons from Bambi staples.

Overall this is a relatively simple body kit, although the chassis modifications might not be for the faint hearted, resulting in a nice model, with a little care.
