The High Capacity Metro Trains are a fleet of electric multiple unit (EMU) trains on order for use by Metro Trains Melbourne on the Melbourne rail network. They are due to enter service in mid-2019 and will eventually become the primary rollingstock used in the Metro Rail Tunnel when it opens in 2025. The HCMTs will carry around 1400 passengers in 7 carriages, running on Melbourne's 1500 V DC overhead catenary system, and will be the most advanced trains in the Metro Trains fleet when they are introduced. A consortium of investors and rail companies is constructing the trains in China and Australia via a contract with the Victorian Government, in addition to upgrade works necessary for the operation of the trains.
As a local company, Top Rail Services becomes one of the core suppliers on HCMT project. In next 6 years, Top Rail Services will continuously provide earth resistors, brake control module and LED lights.
