From 1972, more double decker multiple units were constructed by Comeng and Goninan. These are now known as the S sets. All electric suburban and interurban trains in Greater Sydney are now double deck, though the Sydney Metro (expected to open in 2019) will use single deck carriages. All double deck carriages have two doors per side per carriage, with a vestibule at each end at platform height. The Sydney double deck commuter trains are high.
