SLord Nelson

Once again looking at the steam engines built over the years for railway companies in Great Britain in have one or two that I would like to convert into the Hornby 00 live steam models and one that takes my fancy is the Southern Region Lord Nelson class this is because it has a very large tender and it is hoped would run for longer than the 30 minutes that the Hornby engines run for before they run out of water.

Ironically this was for the same reason as SR had no water troughs so picking up water on the move was not a possibility.
Like all railways about this time building bigger and fast engines was always a challenge plus keeping the weight down to limits that the permanent way could accommodate and this type of 4-cylinder 4-6-0 steam locomotive was going to be the next new designed for the Southern Railway by Richard Maunsell, so in August 1926 the first of the class was rolled out they were intended for Continental boat trains between London Victoria and Dover
Harbour. These express passenger trains were to be about 500 tons and in all sixteen of them were constructed representing the most powerful if not the most successful Southern 4-6-0 design and were all named after famous admirals.

 

The class operated with British Railways until they were withdrawn in 1961 and 1962.
Only one engine of the class survived the first engine built Lord Nelson all the others were sent to the scrap yard.
Richard Maunsell was the Chief Mechanical Engineer at the time and started his design for a 4-cylinder engine with an improved boiler and Belpaire firebox.
The drive would be divided between the front coupled axle for the inside cylinders and the middle coupled axle for the outside cylinders giving better weight distribution and reduced hammer blow. The new design was a compromise between the need for additional power and to keep the weight down to an acceptable limit.
There were two unusual features of the design one was the setting of the crank axles at 135° rather than the standard 90° of other locomotive types. This gave eight beats per
revolution, rather than the usual four this way it would also give an even draw to the fire. The second difference was that fire grate was in two sections, the rear portion was
horizontal and the front sloped away sharply some crews found this hard to fire.

The prototype E850 named Lord Nelson was ordered from Eastleigh railway works in June 1925 but production proceeded slowly at Maunsell’s insistence to ensure that the weight was kept to a minimum at every stage so the locomotive did not appear until August 1926.
It was tested on a variety of duties over the next year, with sufficiently encouraging results for an initial order for ten more locomotives for delivery between May 1928 and April 1929 to be placed.
These were originally scheduled to be allocated to Battersea depot and fitted with 4,000
gallon 6-wheeled tenders suitable for the Continental ports. However, during
construction, it was decided to equip half of the class with 5,000 gallon 8 wheeled tenders necessary for the longer West of England routes which will be the design that I will have a go at these engines were allocate to Nine Elms depot.
A further batch of ten locomotives was ordered in 1928, before the previous batch had been delivered, but when it became apparent that the Stock Market Crash of October 1929 would be likely to reduce the demand for Continental travel, this second order was reduced to five.


I do have an old A3 chassis which was to be part of a GWR tank engine that I was building but will switch it to this engine and hope I can pick up a replacement A3 later for that
conversion.

Looking forward to the build story on this one Ken, nice loco to model.

Yes Rob I'm hoping for a much easier build as it will be about 80% of the Hornby parts

You can see that I’ve made a start and we need the body of the engine built first so that I can get an idea on just how much space is available for the Hornby parts.

One of the good points about this kit is the white metal fire box it is hoped that I can use this as is and do away with the Hornby weight that is fitted inside the A3 and A4 engines.

This way saving space as already if I build this like other engines in my collection I would want to keep the cab empty for a crew.

The tender is the part that interreges me for this will have a larger boiler than the A3 and A4 and steam runs will show if this increases the running time ?

I’m not sure what year this engine should be placed in but maybe keep it in the light green of the Southern Railway.

Still we have a way to go yet as you can see and ideas are coming through the grey Matter fast like when I built the GER S69 engine I used the frames in the kit but this time to save time I might try screwing the frames from the kit onto the Hornby A3 chassis this way the centres of the main drivers can be located from the kit frames and re drilled into the Hornby chassis but all to come.It was said that the first engine took longer to construct than it should this was because the main interest was in keeping the weight down on the overall build to meet the civil engineers requirements.Which reminds me of a job I was on an air born radar each unit had to be weighted this was to keep with in a set overall figure and set at which point for every little increase in weight would mean a reduction in the fuel load. We reckoned by the time we had built the system the plane had just enough fuel to get it to the end of the runway.

Have a look here for the fleet names - does anyone of these have a close assoc with you or your area or maybe carried a livery you like.

At bottom of page is a link to First page which has an informative write up about the variants.

Thanks Rob

i really like Lord Effingham! 

Sir Fancis Drake pirate explorer 1540 - 1596 born near Tavistock Devon he entered the harbour of Cadiz and burned the Spanish fleet he left for expedition to the West Indies in 1595 and died of a fiver in Panama.

So a loco bloke

Effingham 1536 - 1624 second Baron Howard of Effingham eldest son of William Howard he commaned the English fleet escorting King Philips 2nd of Spain  to England to marry Queen Mary in 1554 but later as Lord Admiral was responsible for preventing the same King Philip's Armada from landing in England 34 years later.

Ah - the frames have been laid and construction started - well done!  Smile

 

The Southern didn't use water troughs because it didn't need them. They were considered on the Waterloo - Exeter route but most trains stopped at Salisbury with the 'non-stop' Devon Belle making a water stop at Wilton.

 

In terms of names some locomotives had differing features such as Lord Collingwood was equipped with a double chimney in 1934, Lord Howe had a taper boiler to 1943 and Lord Hawke a long boiler (and a Urie curved-top tender). Lord Hood has smaller driving wheels. Then there were smoke deflectors (or not) although 861 to 865 had them from new........

 

In the late 1930s the class were equipped with large diameter chimneys and self-trimming bunkers (as you are modelling).

I enjoy life - it gives me something to do! - especially modelling BR's Southern Region 1955-61.

If it turns out to be a Heinz with 57 varieties of parts how about Lord Ken of Chuffingham, resplendent with your home grown etched brass coat of arms.

thanks for the history I must log things like this just get things right so keep a watchful eye because I don't know much about these engines.

Rob Lord chuffingham sounds ok I could make a set of plates just for a laugh as they did move plates around didn't they like Winston Churchill i think his funeral train had the name plates switched as WC that look bad? Was in the shops for a refit.

and I think the same happened with King George 5th when he died no doubt someone will put me right if I'm wrong.
