The Craigieburn railway line (previously the Broadmeadows line and Essendon line) is a commuter rail passenger train service operating between Craigieburn in the northern suburbs and Flinders Street in Melbourne, Australia. The service is part of the Public Transport Victoria metropolitan rail network. Description The line rises steadily after leaving North Melbourne until after Essendon, then drops a little to cross Moonee Ponds Creek, and soon after encounters the Glenroy Bank, a continuous rising gradient of 1 in 50 for nearly that taxed locomotive-hauled trains in the days of steam. After Glenroy, it continues to rise Craigieburn and beyond. Earthworks are, however, generally moderate. The almost-continuous gradients were a factor when, in 2003, an unmanned suburban train rolled the length of the line from Broadmeadows to the city, and crashed into a stationary but loaded passenger train waiting to depart Spencer Street station. No one was killed or seriously injured. Infrastructure The line is double track throughout, and controlled by automatic block signalling. It has numerous level crossings and many grade-separated road and rail bridges. Terminating facilities are at Kensington, Newmarket (by shunting onto the Flemington Racecourse line), Essendon, Broadmeadows and Craigieburn. Only Essendon, Broadmeadows, and Craigieburn are normally used, the latter two daily and Essendon in special circumstances. Train stabling is at Broadmeadows and Craigieburn. History The line from North Melbourne to Essendon was opened by the Melbourne & Essendon Railway Company in November 1860. Soon after, the company opened a branch from Newmarket to Flemington Racecourse. Both lines closed after only a short time, in July 1864. The Victorian Railways reopened the Flemington Racecourse line (including the Essendon line as far as Newmarket) in November 1867, and in January 1871 to Essendon. In April 1872, the line was extended to a temporary terminus outside Seymour, awaiting completion of a bridge over the Goulburn River. In December 1894, through services were provided from Essendon to Brighton Beach on the Sandringham line. Automatic Block Signalling started to appear on the line in 1918, with Kensington to Essendon being converted in June of that year, and North Melbourne to Kensington in October. In May 1919, Flinders Street to Essendon and the Sandringham line were the first lines to be electrified in Melbourne, apart from a test installation on the Flemington Racecourse line. In January 1924, an extra pair of tracks, including a flying junction, opened between North Melbourne and Kensington, enabling
