Lietzke Australia, a member of the AM Group, has been working together with UGL Limited Rail Division to develop the train cab door units for the new PH37 Locomotive.

These diesel-electric locomotives have been designed for heavy-haul and freight operations across the narrow gauge networks of Queensland and Western Australia and the Lietzke door units have been designed to suit such operations.

The first shipment of doors has been delivered for these PowerHaul Series Locomotives.
