Overview

Southeastern is the trading name of SE Trains Limited, a train operating company owned by DfT OLR Holdings on behalf of the UK Department for Transport. It took over the South Eastern franchise on 17 October 2021 to maintain services while the government assesses longer-term arrangements. The operator runs frequent commuter and regional services linking outer suburbs and towns into central London.

Network and services

The company operates a mixed network of suburban and longer-distance services. Trains serve south‑east London and commuter corridors into several central London termini, and extend across most of Kent and into parts of East Sussex. Routes include conventional services into London terminals and domestic high‑speed connections that use the high‑speed line to St Pancras. For route maps, service updates and timetables see the operator pages linked below.

Background and transition

The business currently trading as Southeastern replaced the previous private franchisee on 17 October 2021. That change followed financial and contractual concerns relating to the earlier operator. Reports at the time indicated that the previous franchisee had retained around £25 million that the Department for Transport expected to be returned, prompting the Department to transfer responsibility to an operator of last resort to ensure continuity of services.

Rolling stock, operations and customer information

Southeastern operates electric multiple units including standard commuter and high‑speed trains, and is responsible for day‑to‑day service delivery, staffing and station management on many routes. Passengers can check fares, planned engineering works and customer notices on official channels; see the operator information page for practical guidance and contact details: Southeastern information.

Notable points and outlook

As an operator owned by DfT OLR Holdings, Southeastern's role is to provide reliable rail services while the government considers longer-term franchise, concession or partnership models. Improvements to rolling stock, accessibility and service resilience are ongoing priorities; any major changes will be subject to public announcements and regulatory oversight.
