The Chiltern Railway Co. Ltd. provides rail transportation services. It runs scheduled passenger services along the corridor between London Marylebone and Birmingham snow hill, and London Marylebone to Aylesbury via Amersham along the London underground metropolitan line. The company was founded in March 1899 and is headquartered in Sunderland, the United Kingdom.

Vivarail Ltd. is a world leader in battery technology for rail applications. The private company is based in Southam, UK. Vivarail has built class 230 and class 484 trains, using a variety of power systems. Its first pure battery train was launched in 2018, and its next-generation train will be launched at the UN Climate Change Conference. Vivarail has sold trains to a number of UK-based operators and to Railroad Development Corporation as part of its export strategy. With the UK's first battery and battery hybrid trains fully approved for passenger service, Vivarail has proved its ability to deliver independently powered emission-free rolling stock. It means that an electrified network can be achieved without the need and expense of installing new catenary. As well as ensuring good quality existing rolling stock can be retained by converting to battery power – saving waste, energy, and resources while delivering a decarbonized railway. Founded in 2013, the British company has designed and developed emission-free traction systems based around flexible battery operation.
