It seems I missed a few events in the East Hills Line between 1932 and 1987, so I’ll start off by covering those.
The East Hills Line was first opened in 1931, consisting of an electrified double track between Tempe and Kingsgrove, then a single non-electrified track between Kingsgrove through to East Hills. The line was fully electrified in 1939 and duplication extended from Kingsgrove through to Riverwood in 1948.
The line between Riverwood and East Hills remained single track until 1987, when it would be duplicated as part of the extension of the line to meet up with the South Line at Glenfield. This allowed East Hills Line trains to go all the way between Campbelltown or Macarthur in Sydney’s Southwest through to the Sydney CBD. The new line was opened on December 21, 1987 by then NSW Premier Barrie Unsworth (see video below).
Next week: electrification of the Richmond line.
