I want to know the answer to the following question:
What company operates Southampton's local train service?
All the background I'm provided with is that "Local train services operate in the central, southern and eastern sections of the city and are operated by South West Trains, with stations at Swaythling, St Denys, Millbrook, Redbridge, Bitterne, Sholing and Woolston.". Is that enough to answer the question?
Answer: yes
