the years, more stations were added to the line. Sheung Shui station was opened in the 1930s, and Ma Liu Shui (now University) station opened in 1955. The KCR engines were powered by steam engines before the 1950s. There were 20 engines. However, diesel engines were purchased starting from 1950, with the first one with number 51. Steam engines then disappeared from KCR. Change of terminus The development of the towns along the line began to grow immensely during the 1970s, prompting a modernisation of the Kowloon-Canton Railway. The original Kowloon station terminus at Tsim Sha Tsui was too small and had no room for expansion, so a new terminus site was chosen in Hung Hom, then known as Kowloon station. The new Kowloon station replaced the old one in 1975. Today, a clock tower is the only structure left from the old terminus, and is a landmark near the Cultural Centre, Space Museum and the Star Ferry pier. Six pillars were relocated to the Urban Council Centenary Garden in Tsim Sha Tsui East. A big bell is stored at Ho Tung Lau. The original Hung Hom station at Chatham Road South was also demolished. 1980s modernisation In 1975, the KCR asked two consultancies, Sofrerail and Transmark, to make proposals on the modernisation of the line. In 1979, Transmark's proposal to double-track and electrify the entire line for $2.5 billion (in 1979 prices) was accepted by the government. This work involved building a new tunnel through Beacon Hill as the existing tunnel was not wide enough to accommodate two tracks. New stations were added, including Kowloon Tong station, which was completed in 1982 to provide an interchange with the new MTR network. Tai Po Kau station and the original Tai Po Market station were closed, with the latter being redeveloped into the Hong Kong Railway Museum. The development finished in sections between 1982 and 1983, with new Metro Cammell EMUs, manufactured by Metro-Cammell in England, replacing diesel locomotives. With the modernisation of the railway and the concurrent urbanisation of the New Territories, ridership rose quickly, from a daily average of 190,000 in 1983 to 491,000 in 1990. A temporary station in Tai Wai opened in 1983 while the permanent Tai Wai station was completed in 1986. Fo Tan station opened in 1985 to serve the expanding industrial estate. Tai Wo station opened in 1989 to serve Tai Wo Estate. The
