Introduction

Gemini Trains has announced a significant partnership to introduce a new fleet of high-speed trains connecting London with Paris, Brussels, and Cologne. The new services, which will be co-branded, aim to increase competition and capacity on cross-Channel rail routes.

Partnership and Rolling Stock

Following technical and financial evaluations, a manufacturer and financing partner were selected for the project. The trains will utilize a platform designed to reduce energy consumption, improve aerodynamics, and enhance passenger comfort.

Financing and Asset Utilization

A rolling-stock financier will structure and fund the new fleet through its established model of involving institutional investors in major rail projects. This partnership aligns with the goal of maximizing the use of existing high-speed assets.

Service Details

The new rolling-stock partnership expands an existing collaboration, which will co-brand the new international service. The service will operate from London Stratford International, and passengers will be able to book tickets directly via an app.

Maintenance Facilities

Gemini has applied to the Office of Rail and Road (ORR) for capacity at the Temple Mills maintenance depot, currently operated by Eurostar. Access to this facility is considered essential for maintaining the new fleet.
