In 1977 a group of large boxvans were built for Geelong to Campbellfield (Somerton) traffic. They were classed as 'BFW' and numbered 1 to 40.
They were built to transport palletised car parts manufactured at the 'Ford' plant Geelong to the car assembly plant at Campbellfield, near the Upfield station.
They replaced four wheel open vehicles of the _I__ and _IA_ type. These trains were blocks of about 20 to 30 vehicles. They ran loaded Geelong - Newport - Sunshine - Somerton - 'Ford' plant. Sometimes they ran to Melbourne Yard or Caulfield where the locomotive changed ends to continue the journey.
When the train ran with BFW's, the consist was much shorter, about 9 or 10 of the vans, usually hauled by a _T__ loco.
The boxvans were large, about 75' long. They were fitted with FCF_ bogies, couplers and brake gear. With this gear they ran with a low floor height and gooseneck couplers to match existing coupler height.
In the 1979 recoding the class was recoded to VBCW.
