Some of the technical problems reported for Tangaras generally, included brake failure and reported power surge problems. After the accident, they were often blamed by some for being the cause of the accident. Many of the survivors of the accident mentioned a large acceleration before the accident occurred. Furthermore, there was an understanding that the emergency brake should be seldom used because the train would accelerate between before the brake came into effect. It was noted that the G7 trainset was the only train in the Tangara fleet to use 3-phase induction motors, and that these are not able to "run-away". Furthermore, the majority of braking and traction system components were thoroughly examined and tested by experts from Australia and overseas, and found to be working normally. Those damaged in the crash were examined and were also found not to have had pre-existing damage able to cause such an accident.
