Perth's first electrified trains, the A-Series, commenced service in 1990. The new B-series were introduced on the 4th of October 2004 as part of the New MetroRail project. The trains were bought to service the Joondalup Line and Mandurah Line at a cost of A$ 8 999 999 each (≈$9 Million). These trains are stored and cleaned primarily at the Nowergup railway depot.
The B-series trains are capable of service on the Midland, Armadale/Thornlie and Fremantle lines and have been used occasionally during special events (e.g. football matches). However the stations on these lines are not capable of handling double (6 car) sets as the platforms are not long enough, and there are reported problems with the acceleration/deceleration systems with the closely spaced stations. Platforms at the original stations on the Northern Suburbs line had to be lengthened to accommodate the 6 car trains, as did Platform 1 at Showgrounds and both platforms at West Leederville. The Mandurah line stations, along with Clarkson, Currambine and Greenwood on the Northern Suburbs were built with longer platforms with the longer 6-car trains in mind.
B-series trains were introduced on the Thornlie Line in August 2012, operating on a limited schedule during the morning.
- Mounting of traction motors to the sprung body of the railcar rather than to the bogies, resulting in less noise and vibration
- Faster operation with running speeds of 130 km/h, but are capable of speeds up to 260 km/h (however they are not designed to, but could be upgraded in the future) compared with the older sets, which have a maximum of 150 km/h.
- Regenerative braking
- Distinctive styling, with a more contoured exterior
- Other minor aesthetic alterations
- New automatic onboard announcement system (AOA)
- Auxiliary secondary communication via floor to air (FTAC)
The Public Transport Authority ordered a second batch of B-series trains in 2006. This order included 45 new carriages (or 15 new 3-car sets) costing the WA Government A$160 million. The builders of the first batch, Bombardier/EDi Rail, were awarded the contract to build this second batch. To be delivered from 2009 to 2011, the order was made to accommodate greater capacity on the Joondalup and Mandurah lines. Like the older B-series sets, these trains will only be used on the Joondalup and Mandurah lines for regular timetabled services, and as a result displace the remaining A-series trains still operating on these lines. On 28 June 2009, the first of these were introduced into regular service, with some of the older A-series trains being transferred to the Fremantle-Midland line at the same time. These sets feature an upgraded communication system and brighter destination screens than the original B-series sets.
Funding for a third batch of 45 carriages was announced by the WA Government in the 2011-12 State Budget. An order of six additional carriages was confirmed in August 2012 to service the planned Aubin Grove station, and fifteen carriages were ordered in October 2012. 
Accident at Nowergup Depot
On 23 August 2006 at approximately 6pm, two B-series trains (sets 53 and 60) were involved in a head-on collision at Nowergup Depot. Cars from both sets were damaged badly enough to be sent back to builders' EDi/Bombardier facility in Queensland for repair. The cost of the repairs was estimated to be A$1,240,000. During these repairs, undamaged cars from both sets were re-formed into set 60, which then returned to service. The damaged cars were fixed and returned to service (as set 60) in time for the opening of the Mandurah Line in December 2007.
