Alstom secures €1.2 bn contract for Britain’s first mainline battery‑electric trains with TransPennine Express
Executive summary: Alstom and TransPennine Express signed contracts worth €1.2 billion for the supply and long‑term maintenance of a new fleet of battery‑electric trains for Britain’s mainline rail network. The agreement represents the first major mainline battery‑electric train order in the UK, advancing the country’s rail decarbonisation goals and creating a sizable market opportunity for zero‑emission rolling stock.
Who is involved: Alstom (the train manufacturer) and TransPennine Express (the UK train operating company).
Likely next: Alstom will begin production of the battery‑electric units, with delivery and entry into service expected over the coming years, while TPE will integrate the trains into its TransPennine service.
On 11 September 2026, Alstom and TransPennine Express announced a contract worth €1.2 billion for the supply and long‑term maintenance of a new fleet of battery‑electric trains intended for Britain’s mainline network. The deal marks the first major order for battery‑powered rolling stock on the UK’s national rail system, supporting the government’s rail decarbonisation targets. It provides Alstom with a significant revenue stream in the growing zero‑emission train market while giving TPE a pathway to replace diesel units on its TransPennine routes. The contract also includes maintenance, underscoring the long‑term nature of the partnership.
