What is the station ID for London Waterloo
select station_id from station where name = "London Waterloo"
What trains go to station ID 1?
select * from train_station as t1 join station as t2 on t1.station_id = t2.station_id join train as t3 on t3.train_id = t1.train_id where t1.station_id = 1
Can you give me the names of those trains and tell me when they have service
select t3.name, t3.time from train_station as t1 join station as t2 on t1.station_id = t2.station_id join train as t3 on t3.train_id = t1.train_id where t1.station_id = 1
