Suburban Rail Loop Tender

ScopeThe Suburban Rail Loop SRL is a proposed orbital line of the rail network of Melbourne Australia which would traverse suburbs 1525 kilometres 9.315.5 mi from the Central Business District CBD along an approximately 90 km 56 mi route. Although several orbital rail schemes have been proposed and some constructed throughout Melbournes history the SRL received significant new attention in 2018 when the Labor government of Victoria led by Premier Daniel Andrews announced it as a policy in the lead up to the state election of that November.Construction of the SRL would take more than 25 years and cost over AUD50 billion. A substantial portion of the route would be built underground along entirely new rail alignments although the western half would be shared with or formed by the proposed Melbourne Airport rail link and the existing Deer ParkWest Werribee railway line. Four distinct sections have been identified for the staging of construction and operation.Initial planning for the SRL was carried out in secret prior to its announcement and when the plans were released publicity was widespread. The SRL plan was praised for its long-term vision and ambition as well as being an innovative solution to the difficulties faced by Melbournes transport network but criticised for its obvious political motives and enormous cost
