The London, Midland and Scottish Railway (LMS) Fowler 3F is a class of steam locomotives, often known as Jinty. They represent the ultimate development of the Midland Railway's six-coupled tank engines. They could reach speeds of up to 60 mph (97 km/h).[1]
Design of this class was based on rebuilds by Henry Fowler of the Midland Railway 2441 Class introduced in 1899 by Samuel Waite Johnson. These rebuilds featured a Belpaire firebox and improved cab. 422 Jinties were built between 1924 and 1931; this class was just one of the Midland designs used on an ongoing basis by the LMS. The locomotives were built by the ex-L&YR Horwich Works and the private firms Bagnall's, Beardmores, Hunslet, North British and the Vulcan Foundry.

British Railways numbers were the LMS numbers prefixed with '4'. Numbers 47477, 47478, 47479, 47480, 47481, 47655 and 47681 were fitted for push-pull train working.
The first withdrawals started in 1959 and by 1964 half had been withdrawn. The final five survived until 1967, with a further one, 47445 continuing with the National Coal Board.

Thanks to their large numbers, renowned performance and late withdrawals, nine of these engines have been preserved, along with a spare set of frames and a boiler (from 47564). Many were restored within a few years of leaving the scrap heap, and most have a further working life ahead of them. All have steamed in preservation, with the exception of 47445.
One member of the class has operated on the main line in preservation. This was 7298/47298, which took part during the Rainhill celebrations in 1980 when it hauled a number of Steamport residents from the museum in Southport to Rainhill and also took part in the cavalcade. Owned by Ian Riley, in February 2017 it was undergoing its "ten-yearly overhaul"[2] and was expected to return to operation "in a couple of years".[2]

An engine of this class can be seen in the Rev. W. Awdry's The Railway Series book The Eight Famous Engines.[5] The character is named Jinty and comes from the "Other Railway" (a.k.a. British Railways) to help out when the main engines went on a journey to England.
In the video game Transport Tycoon by Chris Sawyer, the Jinty is offered as the cheapest and most basic engine in the game.[6]
An OO gauge model of the Class 3F was first produced by Tri-ang in 1952 and production continued after the company became Hornby Railways in the 1970s. Hornby released a retooled version in 1978 with better detailing and continue to produce that model for their "Railroad" range.
In the 2000s Bachmann Branchline released a more detailed OO model. In N gauge Graham Farish produced a model as a "GP Tank" in various liveries including some of other railway companies before later tooling an accurate 'Jinty' model. In O gauge and Gauge 1 Bachmann Brassworks produce an example. In O gauge, Connoisseur Models produces an etched brass kit. In HO (3.5 mm) scale Firedrake Productions produced a small run of 20 kits.
Darstaed, a model train company in Great Britain, produced O gauge tintype models of the LMS Fowler Class 3F, affectionately referring to them by the nickname of Jinty [7]
Dapol has produced a Jinty for the O gauge market which was released in September 2017 [8]
