The development of the public transportation vehicles such as railway train had an incredible impact on the expansion of human mobility. In constructing the railways, quality assurance must be considered as it is very important to the project. The Malaysian Public Works Department (PWD) has undertaken the East Coast Line Track Rehabilitation Project between Gemas to Mentakab, which is estimated to cost RM220mil, these 123 km-long railway rehabilitation projects would use the reclaimed rails rather than the new rails. The reclaimed rail was manufactured according to the European standard EN 13674-1 and previously installed on site were examined and tested before could safely use in this track rehabilitation project. The reclaimed rails are analysed using ultrasonic inspection, hardness test, tensile test and micro examination to ascertain the safety values of mechanical properties such as tensile properties, hardness properties and microscopic morphology which regards to the composition of the welding joint and rail. Thus, to determine the reclaimed rails able to withstand forces applied on it without causing failure. © Published under licence by IOP Publishing Ltd.
