Question
Hi Michael.  Just wondering - do any London Underground trains physically travel under The Thames river, or do they all use overland bridges?

Answer
Hello Derryl,

Thank you for your question.
In fact, almost all London Underground routes which cross the Thames do so via tunnel - the only crossings by bridge are the district line crossings in West London which travels via the Fulham and Kew Railway bridges, for the Wimbledon & Richmond branches respectively.

You can read more about the various crossings of the Thames on the Wikipedia page at:

Michael
