- Up and Away in Taiwan. Our Hirail being lifted onto the via duct rail system for UT rail testing.
- High-Speed Rail in Taiwan. The new THSR of Taiwan tunnel exit.
- High-Speed Rail in Taiwan. Ultrasonic testing of THSRC high speed line in Taiwan using our rear wheel drive RRV.
- Hong Kong, CATER in Hong Kong working closely with MTR.
- Heavy Haul locos from the Pilbara iron-ore region of Western Australia
- Ore trains working for BHP Billiton and Rio Tinto need reliable track
- Rugged countryside rich in iron-ore in the remote Pilbara region of Western Australia
Historical Rail Flaw Detection Development
- 2 Axle rail bound vehicle circa 1980 from Ultrasound Pty Ltd using 2 wheel probes per side for ultrasonic rail testing.
- Wheel probe RFD testing in a road rail vehicle by Ultrasound Technical Services circa 1970. Taking from concept to production.
- A more sophisticated RFD testing vehicle by Ultrasound Technical Services circa 1976. Computerised and air conditioned.
- The single wheel RFD experimental testing trolley, people and clothing were colour matched to the iron ore dust. Circa late 1960s.
- Yet a more sophisticated, 2 wheel probes per side, ultrasonic RFD testing road rail vehicle circa 1973. Capability, distance and quality of testing is improving.
- The early days (Circa late 1960s) when hands on experimenting was the only way to prove a concept and vehicle air conditioning meant something else. Great job Ken
Flaw Samples
- Rail foot corrosion often goes undetected, especially in crossings and tunnels
- A major break where a small flaw has led to the weld failing.
- Critical gauge corner damage often seen on heavy haul lines.
- Rail profile limits have been reached with reduced head material.
- Broken out rail section from a Bolt Hole Crack. Note the head shape also.
- Severe (!) Wheel Burn defect from an enthusiastic driver before wheel slip control in locomotives was common place
- A Transverse Defect (TD) in carbon rail. A typical pattern of fatigue failure from the gauge corner in an inappropriately worn head rail. Slow growth is in the fine oval section while the rapid break out is the rough surface finished.
- Severe gas cavities and lack of fusion in a carbon rail Thermit Weld.
- A transverse fissure (defect) originating from hydrogen embrittlement cracks, fortunately rarer these days with modern steel making technology
