British Rail Class 88 Bi-Mode Locomotive Introduction
UK · 2016–present (introduction)
The judgement call
Account-gated at launch* The Class 88 represents a pioneering step in UK rail, being the first dual-mode locomotive to utilize 25kV AC electrification. * Strategic choice to enhance operational flexibility and reduce reliance on diesel power where electrification is available.
Key engineering challenges
* Designing and integrating a truly dual-mode locomotive capable of seamless transition between 25kV AC overhead electric and diesel power. * Ensuring optimal performance and reliability across both power modes, particularly for freight operations. * Meeting UK loading gauge and operational requirements for a European-designed locomotive.
