Interurban Multiple Unit (Citytrain)
Encyclopedia
The Interurban Multiple Unit are a class of electric multiple unit
used by Citytrain
in and around South East Queensland
Australia
. The Interurban Multiple Unit comes in three subclasses, Sets 100-110 is known as the 100 series, Sets 121-124 is known as the 120 series, and the newest interurban sets (161-188), which is currently being built jointly by EDI and Bombardier is known as the 160 series.
A Interurban Multiple Unit is a three-car set, operating similarly to an EMU
and a SMU
. Internally, the IMUs are different from the Suburban units, with luggage racks, mobility-access toilet and visual indicator signs provided inside the IMUs. Like most trains in the Citytrain fleet, two three-car IMUs can be attached together to form one six-car set. The 100 series and 120 series are interoperable, and can both operate together in revenue service as a six-car set.
Whilst the IMUs are generally found primarily on Gold Coast and Airport Lines throughout the day, some IMUs may operate on the Sunshine Coast Line and some Suburban services during peak hour.
The carriages for the 100 and 120 series was built and manufactured by Walkers with their partners, ABB
(100 series) and ADtranz
(120 series). The carriages for the 160 series is currently being built and manufactured by EDI and Bombardier.
in the same year. The 120 series IMUs were introduced in 2002 for the opening of the railway line
to Brisbane Airport
The trains are numbered IMU101-IMU110 for Mk I units (100 Series) and IMU121-IMU124 for Mk II units (120 Series). These are fitted with high-backed seats, one toilet per unit and luggage racks in different configurations. 100 and 120 series units are all interoperable.
QR ordered the new IMUs in 2005 in conjunction with the upgrade and duplication of the Gold Coast Line. The units are in service on the network as of May 2007.
In early 2007 during safety checks, it was discovered that air-conditioning units on the trains were 10 mm too wide. This meant that they did not meet safety standards on a 4 metre length of track between Central and Brunswick Street stations.
On Monday 28 May 2007, the first of the new IMUs (161 and 164) entered service on the Gold Coast Line, departing Robina station
in the morning at 7:38am.
