Refurbishment and Electrification
In the 2008/09 State Budget it was announced that five out of six of Adelaide's railway lines are to be electrified commencing with the Noarlunga and Gawler lines in 2013. 58 of the 70 3000/3100 class railcars are to be converted to electric operation while the remaining 12 are to be retained as DMUs for operation on the Belair railway line All of the 3000/3100 cars will be refurbished, which includes buttons to open the doors, upgraded seating and upgraded CCTV.
It is anticipated that all converted 3000 class railcars will be semi-permanently coupled into two car sets sharing a single pantograph, and reclassified as "3200". 3100 already semi-permanently couple will remain unchanged other than being converted to electric traction. All of the 3000/3100 have now been refurbished.
