[ 1 ] In August 1878, the Brisbane Courier reported that the "company is preparing to lay down four miles of railway with 16 pound rails which would carry five ton wagons so logs could be ...
This most likely will be done with laser-optical transmitting transducers in ultrasonic testing. Eliminating contact with the rail could one day allow high-speed detection of flaws. (Testing of rail is currently able to be done at 80 km per hour with a Speno US-6 Ultrasonics train) Another need for the future is a complete rail inspection system.
The earliest rail chairs, made of cast iron and introduced around 1800, were used to fix and support cast-iron rails at their ends; [2] they were also used to join adjacent rails. [ 35 ] In the 1830s rolled T-shaped (or single-flanged T parallel rail ) and I-shaped (or double-flanged T parallel or bullhead ) rails were introduced; both required ...
