Evolved from. 2-6-2+2-6-2. Under the Whyte notation for the classification of steam locomotives by wheel arrangement, a 4-6-2+2-6-4 is a Garratt or Union Garratt articulated locomotive using a pair of 4-6-2 engine units back to back, with the boiler and cab suspended between them. The 4-6-2 wheel arrangement of each engine unit has four leading ...

The racing version of the Speed Six had a wheelbase of 11 feet (132 in; 3,353 mm) [5] and an engine with a compression ratio of 6.1:1 that produced 200 hp (150 kW) at 3500 rpm. [17] Successful in racing, these cars won the 24 Hours of Le Mans in 1929 and 1930 [ 18 ] [ 19 ] with Bentley Boys drivers "Tim" Birkin , Glen Kidston , and Woolf ...
The USRA 2-6-6-2 locomotive is a Mallet, or compound articulated type, having both low-pressure and high-pressure cylinders. The smaller high-pressure cylinders powered the rear set of driving wheels, and the larger low-pressure cylinders powered the forward set of driving wheels. The USRA 2-6-6-2 articulated locomotives were direct ...

Overview. The first locomotives of the 2-6-6-2 wheel arrangement were built in 1906 by the Great Northern Railway to permit longer trains on their heavily graded line over the Cascade Mountains. [5] They were a refinement of the first North American Mallets, 0-6-6-0 engines built for the Baltimore & Ohio in 1904, with leading and trailing ...
