2-8-0+0-8-2

The LNER's sole Class U1.

A 2-8-0+0-8-2, in the Whyte notation for the classification of steam locomotives by wheel arrangement, is a Garratt Articulated locomotive. The wheel arrangement is effectively two 2-8-0 locomotives operating back-to-back. Since in British practice the 2-8-0 type was not normally named, neither was its Garratt equivalent.

Equivalent classifications

Other equivalent classifications are:

• UIC classification: 1D+D1 (also known as German classification and Italian classification)
• French classification: 140+041
• Turkish classification: 45+45
• Swiss classification: 4/5+4/5 up to the early 1920s, later 8/10

Examples

This Garratt arrangement was somewhat common, especially for locomotives intended for freight service. The first 2-8-0+0-8-2 locomotive was a single metre gauge locomotive built by Beyer Peacock in 1924 for the Burma Railways as their class GA.I. The second, and perhaps the best known, was the single Class U1 of the London and North Eastern Railway (LNER) built in 1925. The Burma Railways later purchased another locomotive, classifying it GA.II, and another four of class GA.III.

Other operators included the Bengal Nagpur Railway (2 of class HSG, 5 ft 6 in (1.68 m) gauge), the Ottoman Railway (1 standard gauge), the Mauritius Railway (3 standard gauge), and ten metre gauge examples purchased by the War Department in 1943 and used on the Bengal Assam Railway as their Class MWGX.

A further eight for the Burma Railway were built by Beyer Peacock licensee Krupp of Essen, Germany as Class GA.IV in 1929.
