WheelArrangement 2-8-8-2.svg
The LNER's sole Class U1

In the Whyte notation for the classification of steam locomotives by wheel arrangement, the 2-8-0+0-8-2 is a Garratt articulated locomotive. The wheel arrangement is effectively two 2-8-0 locomotives operating back to back, with the boiler and cab suspended between the two power units. Each power unit has a single pair of leading wheels in a leading truck, followed by four coupled pairs of driving wheels, with no trailing wheels. Since the 2-8-0 type is sometimes known as a Consolidation, the corresponding Garratt type could be referred to as a Double Consolidation. A similar wheel arrangement exists for Mallet type locomotives, but is referred to as 2-8-8-2.

Other equivalent classifications are:


This Garratt wheel 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 better known, was the single Class U1 of the London and North Eastern Railway (LNER), built in 1925.[1]



Apart from their first single class GA.I locomotive of 1924, the 1,000 mm (3 ft 3 38 in) metre gauge Burma Railways acquired another locomotive from Beyer, Peacock in 1927, classifying it GA.II. In that same year another four of class GA.III were placed in service, also from Beyer, Peacock. In 1929 Krupp of Essen, Germany, delivered eight more, designated Class GA.IV.[1][2]


The 5 ft 6 in (1,676 mm) Bengal Nagpur Railway in India used two of class HSG, built by BP in 1925. Ten 1,000 mm (3 ft 3 38 in) metre gauge examples were purchased by the British War Department in 1943 and used on the Bengal Assam Railway in India as their Class MWGX.[1]


Mauritius Railway no. 60

The Mauritius Railway owned three 4 ft 8 12 in (1,435 mm) standard gauge 2-8-0+0-8-2 Garratts, also built by Beyer, Peacock in 1927.[1]


The Ottoman Railways in Turkey acquired a single 4 ft 8 12 in (1,435 mm) standard gauge 2-8-0+0-8-2 Garratt from Beyer, Peacock in 1927.[1]

United Kingdom[edit]

The London and North Eastern Railway (LNER) owned a single Class U1 Garratt, built in 1925.[1]
