An image that is historic in more ways than one!. Back in the days when the Victorian rail systems trackwork was maintained on a more regular basis, B71 heads a down Geelong pass along the up line between North Geelong and Geelong, passing the Plasser as it scrapes out and screens the dirty ballast. The "wrong line move" was being carried out under a system called "Pilot working", designed to enable trains to contine operating during such times with minimul disruption. The same system is still operable, it is now termed "single line working", but is rarely used. The powers that be, along with contemporary OH & S laws, now see such operations carried out under the cover of "absolute occupation", leading to massive cost increases, with the hiring of replacement buses etc. not to mention the delays and inconvenience caused to the travelling public.
Further back down in the dip, T355, with a rake of NN's,waits with some fresh replacement stone.
The Plasser, one of the most impressive maintainance machines purchased with Victorian taxpayers money, was one of the first victims of the State goverments privatisation flop, being quickly snapped up by an overseas buyer.
Also of interest is the flagman, wearing an orange vest. I don't recall seeing too many safety vests during this era.
