1. Articulated
Locomotives
These can be direct drive,
such as the Himalayan Darjeeling class 'D' or Ceylon
Government Rly class H1 Beyer Garratts.
Some very small
Garratt locomotives have dummy outside cylinders with a hidden marine type engine and geared carden
shaft drive, such as C de F Vicinaux du Mayumbe or FCAF No.2 Garratt.
Alternatively, these articulated locomotives can be based on a geared
prototype such as the Shay, New
Zealand Bush logging locomotives or the Avonside 2 and 4 cylinder
geared locomotives used in Natal sugar plantations.
