Their stainless-steel bodies were painted the standard "Tuscan red" to match the livery of the existing fleet.
Cars C3844–3857 were delivered in the blue and white livery of the Public Transport Commission in the 1970s, and repainted to deep Indian red after 1976, before being paint-stripped to run in their original stainless steel finish in the early 1980s.
They were initially marshalled into sets (from S11 onwards) with Tulloch trailers T4841, 4842, and 4845 to 4895, which had their passenger doors modified from manual to power operation.
With the introduction of the Millennium Trains in 2002, several early Comeng power-cars were converted to non-driving trailers, with their pantographs removed, and renumbered T4701–4723.
Ten driving trailers, renumbered D4001 – 4010, were used for two car shuttles in the initial period after the electrification of the Richmond line.
[1] When the Eastern Suburbs Railway was opened in 1979, only stainless-steel Comeng or Goninan double deck cars were meant to operate on this line, but the painted Tulloch double-deck trailers were also used.
[3] These cars were initially branded as a continuation of the K Sets, but were incompatible due to the camshaft controls fitted to the existing fleet.
A farewell tour took place on 6 March, organised by the Sydney Electric Train Society (SETS).
The train operated up the Blue Mountains to Mount Victoria and made a trip to both Hornsby and Fairfield.
The forced ventilation cars were later retrofitted with air-conditioning, and the Beclawat sliding windows replaced by fixed panes in the late 1990s.
Also at this time, the standard light grey internal livery was adopted, and the seats were replaced with blue upholstery.
In 1988, the T sets were introduced as "third generation" rolling stock, also known as the Tangara trains – an aboriginal word meaning "to go".
This train marked a radical departure from the previous double deck car design both in appearance and technically.
Eighty G set cars featuring toilets, high-backed reversible seating and passenger door opening controls were built between 1994 and 1996.
This work involved reupholstered seats, new flooring and handrails, relocated end saloon partitions and a complete internal repaint.
Inter-car doors and handrails are repainted yellow, and the interiors share common fittings with the Millennium and OSCAR cars.
The former ONL cars have had their toilet and water cooler removed and replaced with longitudinal seating, but without the luggage racks found elsewhere in these cars.From 2002, 140 "fourth generation" carriages were introduced, known as Millennium trains or M sets.
The body shells were constructed in China and completed at Newcastle, New South Wales by a joint venture between the NSW Government, Downer Rail, and other companies under a public–private partnership, with delivery between 2011 and 2014 to replace the now withdrawn 6–8 car R & S Set trains.
CRRC Changchun Railway Vehicles manufactured the bodies of the trains before delivering them to Downer EDI, to undergo final assembly.
No trains are currently being maintained at Eveleigh, however the NSW TrainLink D sets are temporarily based here while they undergo acceptance testing.
