Queensland Railways DH Class

The DH Class were narrow-gauge four-axle diesel-hydraulic locomotives they were built by Walkers Ltd for Queensland Railways between 1966 and 1974.
==History==
The DH Class was a successful shunter or a short hauler. They were very useful in floods, because they could work in 2 ft (60.96 cm) of water — 3 times that of diesel-electrics of that time. Their only problem was that they were underpowered, and were replaced by diesel-electrics within twenty years of their introduction.
Only two DH Class locomotives remain on Queensland's railways; DH 72 and 73. These locomotives are based at the Callemondah and Mackay Depots. With the exception of a few that have been bought by heritage groups, most have been re-gauged and rebuilt into heavy crane locomotives. DH 31 (originally DH 59) has been preserved by the Puffing Billy Railway.
==Specifications==
The class weighs 37 tons. The prime mover is one 465 hp (347 kW) Caterpillar D355E that is coupled with a Voith L42U2 hydraulic transmission. The locomotive produces 82 kN tractive effort @ 12 km/h
