1638 in preservation

restoration starting point (21K)1638 is our completed engine and only engine in traffic at present 1638 was the 114th engine to leave Barry, arriving at the Bluebell Railway on the 30th of July 1980. She was bought by Bluebell member George Nickson, and generously donated to the Bluebell following the great success of sister engine 1618. From 1980 until 1993 1638 was kept in Turners sidings at Sheffield Park.

When the Maunsell Society completed 847, the options were to restore 830 or take advantage of an offer from the Bluebell Railway. This offer was to take 1638 on a free 50 lease, on the proviso that she was restored for future use on the Bluebell. This was accepted and she was completed and entered into revnue earning service at the Bluebell railway in February 2006. Check out this page to see the launch. She now looks like this, quite a change from the scrapyard wreck seen above I think you will agree!Ready for the off at Sheffield Park station on the day of the relaunch into active service at the Bluebell Railway

1638 in service with the Southern Railway and British Railways

1638 (14K)1638 got around a bit during her SR/BR career. She cost £4815 to build and was outshopped from Ashford on the 9th May 1931. She was initially allocated to Redhill but following the electrification of the Brighton line in 1933, she was reallocated to Guildford. Yes, like so many of the Bluebell engine, she is yet another Guildford locomotive. She was one of 20 U class engines based here (there only ever were 50!) and like many of the others she worked the North Downs line as well as workings to Eastleigh. She undertook local passenger duties as well as the occasional goods turn and also some semi-fasts to Waterloo.

At her first major overhaul in 1933 she had her number adjusted to 1638 from A638, and at her 2nd general overhaul (1935) she gained smoke deflectors. There was a brief spell at Bournemouth in the autumn of 1936, but the next move followed the reshuffle that came with the electrification of the Portsmouth line in 1937. July of that year took her to Reading, though she still worked the North Downs line. This became a relatively long stay, not moving for 6 years.

Last allocation - Guildford (20K)1943 found 1638 based at Exmouth Junction, but in 1946 she was surplus to requirements and stored in a siding at Eastleigh, and conversion to oil firing. This never happened and in 1947 she was resteamed and sent back to Exmouth Junction. At this time she had a tender swap, losing her 4000 gallon tender in favour of a 3500 gallon type.

She became 31638 at a general overhaul in 1948, after nationalisation and in September 1949 her west country life was over; she went to Stewarts lane. There was then a very unsettled period between 1959 and 1953. She went to Faversham, Kent then Hither Green, Redhill again, Brighton, Eastleigh, Redhill (yet again!) then finally Fratton (near Portsmouth). Take a look at her record card, which reflects many of these changes.

Chief workings here would have been the Portsmouth to Brighton services and the Portsmouth toPokesdown 1958 (10K) Salisbury (via Southampton) services. At Fratton she worked on the Portsmouth docks line, previously restricted to the Stroudley E1's. At this time she had her second tender change. She stayed here until November 1959 when Fratton shed was closed and she went to her final shed, after an absence of 22 years, namely Guildford. She worked here up until the end in January 1964, having been sold to Woodhams scrapyard in south Wales, along with the other 3 preserved U class engines. When withdrawn, 1638 had had 10 general overhauls and had covered about 915,000 miles in her 33 years (the confirmed figure to March 1962 being 868,853)
