The Interurban Multiple Units are a class of electric multiple units manufactured by Walkers Limited/Downer EDI Rail, Maryborough for Queensland Rail's Citytrain division between 1996 and 2011. The Interurban Multiple Unit is divided into in three subclasses, sets 101-110 as the 100 series, sets 121-124 as the 120 series, and sets 161-188, as the 160 series. The IMUs primarily operate services on Gold Coast and Airport lines, as well as some services on the Sunshine Coast line and peak hour suburban services.
The Interurban Multiple Units are a three-carriage long distance version of the Suburban Multiple Units. Internally, the IMUs differ from the SMUs, being fitted 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.
100 & 120 series
To provide rolling stock for the new Gold Coast line to Helensvale, in 1993 a contract for four 100 class sets was awarded to Walkers Limited, Maryborough. As these were never going to be adequate to operate all services on the line, in July 1995 a further six were ordered.
These are fitted with high-backed seats, one toilet per unit and luggage racks in different configurations. The 100 series and 120 series are interoperable, and operate together in revenue service as six-car sets.
In 2004 Queensland Rail ordered sixteen 160 series sets to provide extra rolling stock in conjunction with the upgrade and duplication of the Gold Coast line. The 160 series were manufactured by Downer EDI Rail, Maryborough in partnership with Bombardier Transportation.
On 28 May 2007, the first of the new IMUs entered service on the Gold Coast line.
