By December 2020 the SWR mainland fleet will undergo a facelift. Ninety new British-built Aventra trains be introduced (750 carriages, in five and 10 car formations), and the rest of the fleet will be refurbished and refreshed. Ultimately this will increase capacity by 52,000 extra seats through the morning and evening peak by 2020. Improved Wi-Fi (up to 5x faster), at-seat charging points, toilet provision on all suburban trains, infotainment systems and better on-board customer information will make passenger journeys better.
