Sydney Trains rolling stock

The Sydney Trains fleet serves the metropolitan lines within Sydney, Australia. All of the rolling stock are double deck electric multiple units and operate mainly as eight carriage sets.

The following lists all rolling stock to have operated under Sydney Trains.

In 1972, the first Comeng constructed stainless steel double deck power cars entered service. These cars (C3805–3857) were loosely based on the recently introduced inter urban cars, the V set. 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. Internally, they had reversible seating with a light tan upholstery, and a grey and off white internal livery. Beclawat sliding windows were fitted to the upper and lower decks, with drop windows in the doors. The sliding windows were replaced with Hopper windows in the 1990s and internally they were repainted light grey with blue upholstered seating. These motor cars had tapered ends, which were fitted with destination boards in the 1990s. 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.

In 1973, additional 54 Comeng power cars C3858 – 3911, and 56 Comeng trailer cars T4921 – 4962, were ordered to coincide with the opening of the Eastern suburbs railway line. These trailer cars were the first to be of stainless steel construction, and they had an extra row of seats on the top deck (and are thus distinguished by an extra single window at the centre of the car on both decks). Ten driving trailers D4011 – 4020 were built with small driver's compartments for 2 car trains. However, they never saw service as driving cars due to Union bans. Subsequently, 25 driving trailer cars D4021 – 4045 (with large guard's compartments) were also built to be paired with a driving motor car to allow 2 car sets to be operated. Ten driving trailers were diesel hauled on South Coast suburban services, south of Thirroul, prior to electrification. Ten driving trailers, renumbered D4001 – 4010, were used for two car shuttles in the initial period after the electrification of the Richmond line. These driving trailer cars subsequently had their driving equipment removed and were converted into standard non driving trailer cars. Extended orders saw the Comeng double deck fleet expanded to include power cars C3912–3986 & 3741–3765, trailers T4963–4987 and driving trailers D4046–4095 by 1982. By 1976, one quarter of suburban cars were double deck. All the 1973 cars are now integrated with earlier stock and operate as L, R & S Sets. 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.

In the 1970s, A Goninan & Co in Newcastle entered the passenger car construction market building 80 power cars C3001 – 3080 and 70 trailer cars T4101 – 4170. Unlike the Comeng cars, the power cars had a flat front end and Pullman Standard fluting, and the upper deck passenger windows were set significantly lower than the earlier Comeng cars reducing passenger sight lines (a source of complaint from passengers).

In 1986, a new generation of advanced suburban passenger train was being considered by the State Rail Authority. There was a delay in the construction of these trains, and 56 interim stainless steel air conditioned cars, C3581–3608 and T4247–4274, were built by Goninan, known as the 'Chopper Cars' for their chopper control. These cars trialled several features of the next generation cars, such as fixed seating, door chimes and passenger address systems. They were originally fitted with a push button feature, to enable passengers to open the doors manually, but this feature was short lived. They retained the flat ends of the previous Goninan cars, but with the addition of a fibreglass moulded end piece which was originally white with orange and red stripes (the 'candy' State Rail livery). These ends were later painted grey with a lower yellow section which they retain to this day, and internally the standard grey livery and blue seat upholstery was applied. 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. Often, the sets would 'jerk' while accelerating when coupled together. These cars were later rebranded as C sets, to differentiate them from K Sets. They continued to operate until the second batch of B sets started entering service from late 2020. The last train was withdrawn on 26 February 2021, after operating its last revenue run on 90 W from the city to Liverpool via Bankstown. 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. Initially, no sets were to be preserved due to the small fleet, however, SETS will preserve one 4 car set as of July 2021. This set has been confirmed to be formed of cars C3584, T4266 (both from set C5), T4274 and C3608 (both from set C9). C3608 and T4274 are significant for being the final stainless steel power and trailer cars respectively built for the Sydney network.

In 1981, Goninan built the first air conditioned cars for the Sydney suburban network. Until then, Sydney had lagged somewhat behind other cities that had commenced the introduction of air conditioned stock. In order to fit the air conditioning equipment into the motor cars, the pantographs were moved to the trailers, effectively meaning that a motor car must remain semi permanently coupled to a trailer car. Four driving trailer cars D4096–4099 were also ordered, allowing 2 car sets to be operated with power cars C3501–3504. The first 8 car set (R1) was delivered with air conditioning, followed by 90 forced ventilation cars C3505–3549 & T4171–4215, during the delivery process for this order, C3550 and T4216 were delivered, fully fitted with air conditioning. Following this, the next order, numbered from C3551 and T4217, were also fitted with forced air ventilation, and were the first to be fitted with air conditioning. The first 100 cars had their upper deck windows at the unpopular lower height of the earlier Goninan cars, the final 60 were modified and these final 60 were distinguished by their front end being painted into the 'candy' white, orange and red State Rail livery of the time. The final batch (C3551 3580 & T4217 4246) also featured bright yellow internal walls. 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. The $1.7 billion contract was awarded to Downer EDI. CRRC Changchun Railway Vehicles manufactured the bodies of the trains before delivering them to Downer EDI, to undergo final assembly. More than 90 percent of the design is shared with the original A sets. The first B set was unveiled in Auburn in March 2018. After undergoing months of testing, Set B2 was the first to enter revenue service on 7 September 2018. The B sets replaced the remaining S sets by the end of June 2019.

Sydney Trains' electric trains are based at maintenance depots. The colour of target plate at the front of each train shows the depot the train was originally based at. Over the years, many trains have been transferred between depots without changing their target plate colour, so the colours no longer have much meaning.

No trains are currently being maintained at Eveleigh, however the NSW TrainLink D sets are temporarily based here while they undergo acceptance testing.

UGL Unipart Rail Services carry out maintenance to the various types of sets they maintain at the depot to which the train concerned is allocated but major work may be done at Auburn Maintain.
