at Lower Plenty Road. On two consecutive days in September 1964, automatic signalling was provided between Westgarth and Fairfield, and Fairfield and Alphington. Macleod to Greensborough was duplicated and converted to automatic signalling in August 1979. The duplication also included a number of level crossing removals and a rebuilt Watsonia station. Weekend services commenced through running to Hurstbridge in April 1985. Previously, weekend services between Eltham and Hurstbridge operated as a shuttle service, with passengers required to change trains at Eltham. Prior to the timetable change, the shuttle service was provided by a double ended motored Tait train, and after their withdrawal in 1984, the shuttle service was provided by a 3 car Hitachi or Comeng. Since 2017, the Comeng trains on the Hurstbridge line had been retired to replaced by X'Trapolis 100 trains, it serves also with the Mernda railway line connection on the Clifton Hill group. The short section between Clifton Hill and Westgarth, crossing the moderately-deep valley of the Merri Creek, was duplicated in January 2009. The rarely used centre running line at Clifton Hill was also removed at this time. As a part of the upgrades undertaken by operator Metro Trains Melbourne, the superstructure of the Burgundy Street bridge near Heidelberg station was replaced in June 2010, costing over $1,000,000. Several stations on the Hurstbridge line formerly had goods yards or sidings. Those at Fairfield, Alphington, Ivanhoe, Heidelberg and Greensborough have been removed completely (although a single track remained at Heidelberg for many years for stabling defective trains). The former goods yards at Eltham and Hurstbridge are now used as stabling sidings, following modifications to the track layout. The siding at Diamond Creek was originally used for goods purposes (according to the 1926 Curves and Grades book) and was retained for use as a crossing loop. A platform was not built on the loop until 1994, requiring trains to "set back" after using the platform in order to cross. The name of Wattleglen station is curious, because the town is named Wattle Glen. Platform signs also read "Wattle Glen," but the station appears as Wattleglen on some official railway documents, and is gazetted as such on the State Government VicNames register. Upgrades In May 2016, Victorian State Government allocated the funding for duplication of section between Heidelberg and Rosanna stations. Upgrade includes construction of second railway bridge over Burgundy Street in Heidelberg, second tunnel for Flinders
