When KTMB started the second double-track project from Rawang to Ipoh, employees were trained in maintenance and operation of the new ILTIS signalling system. Most programmes in relation to this double-track project were conducted by the respective suppliers and manufacturers. For example, Queensland Rail (QR), Australia, provided various specialist training programmes to selected track employees. Areas covered included maintenance of high- speed lines, track welding, rail turnouts, etc.
