From which London train station can you take a train to Bath?

Paddington Station is the correct choice for taking a train to Bath. This station serves Great Western Railway services, which operate direct trains to Bath Spa station. The journey typically takes around one and a half to two hours, depending on the service. Paddington is well-known for its connections to the west of England, including other destinations like Bristol and Exeter, making it a key departure point for those traveling to Bath.

In contrast, the other stations listed do not provide direct train services to Bath. Victoria primarily serves trains to the south and southeast of London, such as to Brighton and Gatwick. St Pancras is best known for international services, particularly Eurostar to continental Europe, and regional trains to the East Midlands and further north, with no direct links to Bath. Waterloo mainly handles services to southwest London and beyond but does not connect to Bath directly. Thus, Paddington is the only station listed that offers direct trains to Bath, establishing it as the right answer.
