entire line to light rail, partial conversion, or closing parts of the line and running the light rail via Sydney Road. Those proposals were finally put to rest in April 1995, when it was announced that $23 million would be spent upgrading the line. The work included the provision of power signalling for the whole line, and the installation of boomgates at all level crossings, except for a few that were closed instead. At that time, many of the numerous level crossings on the line were still controlled by gate keepers, who opened and closed the gates manually for every train. Automatic signalling was extended from Jewell to Brunswick in September 1998, and from Moreland to Batman in October. The commissioning of the final section in November, from Batman to Upfield, coincided with the extension of track duplication from Fawkner to Gowrie. Level crossing removals Future The PTV Network Development Plan proposed electrifying the Upfield line to Wallan railway station to extend the Upfield railway line from its current terminus at Upfield railway station to Wallan railway station. Services The Upfield line has one of the least-frequent peak-period services in Melbourne's railway network, with trains operating every 18 minutes during the morning peak, and 20 minutes during the remainder of the day on weekdays (including peak periods) and weekends, and every 30 minutes during early morning, Sundays and throughout the later evening through to the last train. Until the late 1990s, when the line was under threat of closure or conversion to light rail, late evening and Sunday services were provided by nearby tram lines and a bus service that connected with the end of the nearby tram line. In mid-2004, the majority of peak services were increased from 3-carriage to 6-carriage trains. The line also has one of the lowest proportion of premium stations amongst Melbourne's railway lines, there being only three stations on the line (past the junction at North Melbourne) classified as Premium stations. These are Coburg, Gowrie and Upfield. Brunswick was initially announced as one of the host stations throughout Melbourne's network, however up until November 2006 this has not occurred. During the 2006 Commonwealth Games the area around Royal Park station was home to various event venues as well as the athlete's village, and as such this station was heavily staffed during the Games.
