The East Coast Peninsular Malaysia railway track, built between 1910 and 1930 and running from Gemas to Tumpat for a distance of 527 kilometres, was heavily damaged during massive monsoon flooding that occured between 15 December 2014 and 3 January 2015. Stretches of track were inundated by mud, and washed away – including the steel truss Peel Bridge built in 1931. EDTP 1, from Rawang to Ipoh, included electrification works, double tracking and alignment changes to the railway track. As a result of these upgrades, the track speed was doubled from 80 km/h to 160 km/h, enabling travel times between Kuala Lumpur and Ipoh of just over 2 hours compared to 5 hours previously. The work scope under EDTP 2, from Ipoh to Padang Besar, additionally included design and construction of trackworks involving structures such as the swing bridge in Prai, 3.3 km twin bored tunnels, a 3.5 km marine viaduct, and 51 km of land viaduct over farm land. Through these projects, Emrail achieved successful completion of over 1,000km of trackworks.
