SAS webinar with TAAV on Friday, June 28: Development of Green Track Rail Damper (GTRD)

Abstract

Bangkok is considered as a big city with the population over 8 million people. Without a doubt, the traffic congestion is a problem of Bangkok. Urban rail traffic is a good option to commute in Bangkok. The first urban railway in Bangkok was opened in 1999. At the time, the number of the place of residence was not dense as today and the noise concern at the time was low. Nowadays, the number of condominiums that were built closed to the rail track increases, the complains about the noise also increases as a consequence. Although Bangkok’s urban railway came before the residences, it is unavoidable to take the problem in to the responsibility. A common solution to the noise problem is the noise barrier. Unfortunately, the noise barrier seems not to be a good solution to the urban railway because the limit of the space, the weight of the barrier, and the visual aesthetic. An alternative approach to solve railway noise problems is the rail damper which is suitable for urban railway noise problem. In this presentation, Green Track Rail Damper (GTRD) is introduced. GTRD has natural rubber as a compound thus it is recyclable. The development, test, and assessment of the GTRD will be discussed.
