The meeting will be held at the Trinity Centre in Wallington
People concerned about local train services will have the chance to quiz rail bosses next week.
Carshalton and Wallington MP Tom Brake said: "As a commuter myself I know how frustrating it is when trains are delayed, cancelled, or when you struggle to get on a train, let alone get a seat.
"That is why I have asked rail bosses to come to Wallington and explain what they will be doing to improve train services."
Thameslink Govia owns Southern rail and took over the Thameslink train services in September.
Meeting with rail bosses; Trinity Centre, Maldon Road, Wallington, SM6 8BL; 7pm, Thursday October 23.
