METRO Class 777 IPEMU

The new battery traction equipment is mounted in the underframe and the cooling system is located on the roof. The interior, the high levels of passenger comfort, and the number of passengers it can carry, are the same, with the IPEMU retaining all the basic functionalities of the Class 777. IPEMU trains can operate beyond the electrified third rail network on non-electrified systems, preventing costly infrastructure changes for clients, who can extend the network beyond the third rail. This provides greater flexibility and means more services for passengers. While an IPEMU is running on the electrified network, the batteries can be charged from the third rail, as well as through regenerative braking. IPEMUs have the potential to replace diesel powered units, which helps clients and local and national governments meet decarbonisation targets. The ride quality is smooth and passengers will not notice the transition from EMU to IPEMU mode. Furthermore, IPEMUs avoid passengers having to change trains, enhancing the journey experience and reducing travel time. IPEMUs can be recharged in less than 15 minutes. The IPEMU battery can undergo more than 10,000 charge/discharge cycles.
