830 in preservation as at sale time in 2000

current condition (16K)This is not a happy story!. The good bit is that 830 survives and gets attention sufficient to ensure that there is no further decline in her condition; a holding operation.

She was bought by Maunsell member David Jones with a view, originally to supplying spares for 847. She was rescued from Woodhams scrapyard at Barry in September 1987, the 192nd engine to leave the yard. As there were only 213 engines to be rescued, you can imagine that there are 1 or 2 problems with her. Among these are

  1. She is heavily stripped. What we have is frames, cylinders wheel sets and a boiler. A few things extra too but not much!
  2. Her boiler is not in good shape, it will require extensive (expensive) repairs.
  3. We don't have a tender. We do have a "Plan B" 6 wheel tender as used by S15's... but unfortunately not by 830, it would be historically inaccurate.
  4. Apart from the expense, she needs loving care, and I mean lots; and we have our resources fully extended restoring 1638 (see current project). Don't forget we do this for fun not as a millstone gaining exercise!
  5. The last point is owner ship, read on...

830 in the sidings (67K)830 has resided at Sheffield Park on the Bluebell from the outset, after purchase. There have been many ideas regarding 830. The leading example of this was to convert 830 to a King Arthur class engine as only the national collections Sir Lamiel No.777 survives. Also 830 has the boiler that once belonged to No.763 Sir Bors De Ganis This would require new frames to be made as we would also need new wheel sets. This depletes our starting list somewhat and the cost would be horrendous. Also we are making a replica not restoring an engine by doing this. This plan has been dropped. 830 was to be restored after 1638, as 830, an S15 engine. At a special meeting during 1996, it was resolved to buy 830 from David Jones, for a very reasonable £5000, that's less than scrap value, with a 6 wheel tender thrown in for good measure. The Society then owned the loco, for resources to be allocated in years to come with confidence.

Subsequent meetings to discuss 830 felt that the project was too big for us at this time, with 4 other engines to look after, and it was resolved to sell her. This was not a decision taken lightly, but was done with the interests of the engine in mind. Someone else could have the chance to restore her within a respectable timespan. When an offer came in, it was coincidental that the chance to buy Stowe, a complete and prestigious engine came up. What was best for the engine then matched what was best for the society too, and the deal was done.

830 in Southern railway and BR service

with ballast train July 1961 (10K)When the Southern needed some express freight engines in 1926, Maunsell had no qualms about updating and using Robert Uries S15 design. Why not?.. it was a good one. 2 batches were made, one in 1927 of 15 engines, and one in 1936 of 10 engines. 830 was in the first batch, and emerged from Eastleigh works in August 1927.

Her first shed allocation was Salisbury, where she worked the south western main line. Almost all her working life was spent here. That's a span of 37 years. She was only reallocated once, going to Feltham, west London in January 1964. this though was just a precursor to withdrawal which came shortly after in July of the same year.

Chard Junction 1963 (12K)In 1930 she gained smoke deflectors ( along with most Maunsell engines at this time) and lost the "E" prefix to her number. She was in lined out olive green at this time. In 1940 this changed to unlined dark olive with Bulleid style lettering and in 1942 this became wartime black. She stayed in unlined black for the rest of her working life.

During her 35 years, she clocked up 1.2 million miles on that main line to the south west. That represents good value I reckon on her initial construction price of £6,585.
