LMS Stanier Class 5 4-6-0 No. 44806 is a preserved British steam locomotive.
It was built at Derby in 1944.
Numbered 4806 by the LMS, after nationalisation in 1948, it had 40000 added to its number
under British Railways. 44806 was one of the last locomotives to be withdrawn from service,
surviving until 1968, the last year of steam on British Railways steam.
44806 was an early candidate for preservation, moving directly from BR to the "Steamtown"
collection at Carnforth, housed in the same loco depot where steam's final fires had been
dropped only recently before.
It fortunately avoided the usual years of neglect and parts-stripping at Woodham Brothers
scrapyard in Barry, Vale of Glamorgan, South Wales.
In preservation it was also unusually well-travelled between museums and lines, although staying
in the North West of England.
Some years were spent based in Accrington, with working excursions to a planned preserved
line at Helmshore.
Although these exact plans never quite came to fruition after the station's closure in
1972, most of the line survived as what is now the East Lancashire Railway.
In 1973, 44806 was based for a short time at the newly reopened Lakeside and Haverthwaite
Railway, as their largest and only tender engine.
Operating a large tender engine was difficult though, on a line without a turntable.
Whilst at Haverthwaite, 44806 was adopted by the ITV children's TV series Magpie and
named "Magpie".
The Magpie programme was always in competition with the BBC's comparable Blue Peter, who
had earlier adopted the LNER A2 Peppercorn 532 Blue Peter, conveniently built under that
name.
Shortly after this, a crack was found in the boiler, in the outer firebox.
Haverthwaite did not have the workshop facilities for an engine of this length or weight, so
it was moved, this time to "Steamport" in Southport.
These were busy times for the British steam preservation movement, with many new projects
and scrapyard rescues all competing for attention, time and money.
As a result, 'Magpie' languished.
In 1983, with a wind-down of Steamport owing to pressure over the site, Magpie moved to
Manchester and the Museum of Science and Industry, as a purely static exhibit.
In 1993, 44806, with its 20-year-old firebox crack, travelled to the Llangollen Railway,
where repair work began.
This work took almost three years to complete, with a return to steam on 15 September 1995.
It worked on the Llangollen for nearly ten years, first back as 4806 in black LMS livery
with red lining, then once again as 44806 wearing the BR "ferret and a dartboard" tender
badges with red and white lining.
The expiration of the locomotive's 10 year boiler certificate prompted another rebuild.
The work this time was less serious, being mostly wear items such as boiler tubes, firebox
stays and worn tyres, but any work on engines of this size is a major undertaking.
The work was completed successfully and 4806 returned to steam on 29 August 2007 and was
back in service on 14 September.
The new livery was again BR period, but this time in unlined gloss black.
Since its initial preservation, 44806 had been privately owned by one man, Ken Aldcroft.
Aldcroft died in 2003, 44806 passing to his daughter Ms Renee Wyatt.
To commemorate Aldcroft's 35 years of preservation, 44806 was renamed Kenneth Aldcroft.
44806 Kenneth Aldcroft was based and working at the Llangollen Railway. 2008 was the 40th
anniversary of the end of British Railways steam, and of 44806's own preservation.
In July 2013, the locomotive was offered for sale, and has been purchased by the North
Yorkshire Moors Railway.t the NYMR, it is destined to be certified to run to Whitby
after its overhaul in 2017.
