The Comeng train (pronounced com-eng, after the company name) is a type of electric train that operates on the suburban railway network of Melbourne, Australia. They first appeared on the network in VicRail teacup livery in 1981 to replace the last of the 60-year-old Tait trains. More were ordered after the failed refurbishment and subsequent withdrawal of the Harris trains. In total 570 carriages (380 motor cars and 190 trailer cars, a total of 95 six carriage sets) were built by Comeng, Dandenong.
The Comeng trains are single deck and are semi-permanently coupled as M-T-M (motor-trailer-motor) sets, but these sets spend much of their time coupled in pairs as six-carriage sets.
Comeng trains have power operated doors that must be pulled open by hand but are closed by the driver. The trains were the first suburban trains in Melbourne to have air-conditioning in the passenger saloon. (The older Hitachi trains having had driver only air-conditioning fitted more recently.)
They operate in larger numbers on the Northern, Dandenong, Cross City and Sandringham group lines, although some are continuing to run on the Burnley and Clifton Hill group lines which are serviced by a higher proportion of newer X'Trapolis trains.
The Alstom and EDi Rail sets have a number of differences, including:
- Interior arrangement - The interior LED displays on the M>Train trains were in the middle, as opposed to being at both ends of the carriage on Connex sets.
- Upholstery - Seats in M>Train trains are blue, while Connex opted for rainbow-textured seats.
- Seating arrangement - Connex provided a different seating layout from M>Train.
- Exterior front panels - Information on the train's terminus is displayed on top of the window on M>Train fleets, while Connex trains have them displaying on the left window (in the pre-refurbishment style).
- Cab layout - The EDI Rail refurbished trains retained a second full-size seat on the right-hand side of the cab, originally used for the guard, whereas the Alstom sets only have a small seat, the same size as the passenger ones.
- Cab fittings - The EDi Rail trains also have a windscreen-wiper on both sides, the Alstom sets only having one on the driver's side.
- Light fittings - The Alstom refurbished trains have grated light coverings, while the EDi type retained the original flat coverings.
After Connex assumed responsibility for all of Melbourne's suburban train network in 2004, the EDi refurbished trains had the M>Train exterior logos removed, and later received Connex blue and yellow side stripes, and a repainted front panel.
From December 2006 both fleets were allowed to run system wide. The electronics of both Comeng types were altered to make them electronically compatible with each other, with both the PID voices and display formatting altered. Both types of Comeng can run system wide and can run in multiple unit with trains of the same or different type.
From the beginning of March 2009, Connex ran a test set of carriages with new seating arrangement on city lines. The new arrangements removed 44 seats, making room for more standing on the train. The changes were made to accommodate the increased patronage on the Melbourne rail network.
As part of its franchise agreement, Metro Trains Melbourne is required to modify the seating layout of all Comeng trains to have 2-2 seating which allows better passenger flow through the train and more standing room. So far most Comengs have had modifications to seating around the passenger doors to avoid people clogging up the doorways when a train is overcrowded.
12 Comeng carriages have been scrapped or removed from service.
Eight carriages have been scrapped: 315M, 388M, 1165T, 1109T, 533M, 305M, 1003T and 306M. 315M was burnt out at Hurstbridge on 9 April 1983, along with Tait 472M, 388M was hit by V/Line locomotive N457 at Officer, 1165T was burnt out at Northcote, 1109T was damaged in a collision at Epping, while 533M was burnt out by vandals at Merlynston in April 2002. Both 1109T and 533M were stored at the Ballarat Workshops and were scrapped in August 2010. In November 2012, 305M-1003T-306M crashed into a truck at Abbotts Road in Dandenong South. These cars were stored in Dandenong South near the crash site, visible from the Cranbourne Line until May 2014, when they were scrapped.
Another four carriages have been stored: 500M, 671M, 672M, and 1186T. 500M was burnt out at Sandringham in 2002 and can be seen in a yard close to the North Williamstown station side of the Newport railway workshops. 671M was partly burnt out at Gowrie. Spare cars 672M and 1186T underwent a prototype refurbishment before being stored. 671M is currently in use by the Metropolitan Fire Brigade for firefighter training.
The Comeng fleet is currently having new handles trialled to make it harder to force open doors, following an incident at Watergardens railway station where a teenager forced a door open while the train was moving.
Metro Trains Melbourne are in the process of upgrading Comeng fleet with new seat covers, handholds and new LED lighting (internal and external). By end of 2019, 75% of the fleet would have the new upgrades.
