[Abstract]: This dissertation is an investigation into the feasibility of automating the static twist test procedure currently performed at Queensland Rail. The aim is to select equipment that can perform this procedure automatically while staying within the confines of a budget.

The test requires synchronous jacking of train wheels and it was concluded from the research carried out that synchronous lifting of heavy objects can be successfully achieved through the use of ‘digital hydraulics’, a term
explained in detail within this dissertation. The concept of digital hydraulics was tested for application to the twist test and was found to be completely successful.

A final system design is specified, including equipment such as position transducers, hydraulic cylinders and a PLC. The equipment exceeds the budget specified by Queensland Rail. However it proves that a successful system can be constructed for reasonable cost.
