LMS Stanier Class 8F No. 8151, British Railways No. 48151, is a preserved British steam locomotive.

8151 was renumbered as 48151 by British railways after the 1948 nationalisation.

After completion at Crewe works in September 1942 she was allocated to Grangemouth shed until 1949 when she was transferred to Canklow (19C) shed where she was based until December 1962. Other sheds she was based at during her career also included Stavely (today the Barrow Hill roundhouse) Jan 1963-Apr 1964, Edge Hill in Liverpool from Apr 1964 to Mar 1966 and finally Northwich until she was withdrawn in January 1968 with a working life of just over 25 years. After being withdrawn she was due to be sent away for scrapping at a nearby scrapyard, however she was sent down to Barry scrapyard in South Wales where she remained for over 8 years.

She was bought for preservation in 1975 and was based at the Embsay and Bolton Abbey Railway for a number of years. She was eventually bought by David Smith and after her heavy restoration was completed she returned to steam in 1987, initially at the Midland Railway - Butterley. Shortly after resteaming, she was certified for mainline use and became a regular runner on the mainline. Since emerging from her most recent overhaul in 2010 she is as of 2016 operational on the mainline and is operated by West Coast Railways.

She even during part of her preserved career carried the nameplates "Gauge O Guild", these were however removed prior to the 2012 season as it was planned to have her look more authentic for the season and haven't been re-applied since.

In Nov 1995 she was loaned for a short time to Tunstead Quary to haul a 975-ton train of hopper wagons, she also 5 years later in Dec 2000 worked a special one off freight train along the Settle and Carlisle line from Hellifield to Ribblehead Quarry where the hopper wagons were loaded and she then worked the loaded train on from Ribblehead Quarry to Carlisle. Also in 2000, she made her first operational visit to a heritage railway, when she visited the Great Central Railway for a brief period in June of that year, as well as making a brief visit back to Stavely the following month, now the Barrow Hill Roundhouse.
