The Millennium train, just like the entire
Sydney Trains fleet, is a
double decker. It is a four car consist, with the middle two cars being non-control motor cars and the two outer cars being driving control trailer cars fitted with the
pantograph. The Millennium train was the first to be equipped with an
AC drive system unlike the
Tangara, which has a
DC drive system. The sets usually operate in eight-car formations with two four-car sets combined. While the Millennium train concept is an evolution of the Tangara concept (manufactured by
A Goninan & Co), the Millennium train introduced new features such as internal electronic destination indicators, automated digital voice announcements for upcoming stops, a return to reversible seating, surveillance cameras, wider stairways, a new safety yellow colour scheme, and push-button opened internal doors. The Millennium Train also introduced
crumple zones to absorb impact in a collision. Interiors were designed by Transport Design International. The train also features emergency help points, allowing passengers to contact the train crew in an emergency. The help points are located on the sides of the stairwell to the upper deck. There are actually two help points in the same location, with a large one at face height with a microphone and speaker, and a lower one with a microphone only. There are also emergency door releases which were retrofitted to the trains. These allow passengers to manually open the doors in an emergency, as recommended in the report for the
Waterfall rail accident. The retrofit program was stated as having been completed in November 2014. Like with the
T,
A and B sets, the M sets feature
Scharfenberg couplers. M sets are wide, being classed by Transport for NSW as medium-width trains, which allows them to operate within the whole
Sydney Trains suburban network. Unlike sets M2–M35, set M1 has a slightly different interior design with differently coloured doors and different seat handles likely due to M1 being the prototype M Set. == Delivery ==
