How long is the Underground train journey from Marylebone to Waterloo Station?

Question

Does anybody know how long the journey is? Please help!

Answer 1

It takes about 12 minutes  

Answer 2

I'd say about 20 mins. You've got to change at Baker Street and wait for the Jubilee which might take a while. Also give it  few mins extra, sometimes trains run slow, there might be a signal failure or a red light. Always good to give it a few mins extra.  

Answer 3

According to tfl.gov.uk, it's 12-13 minutes. The Bakerloo line runs straight from the two tube stations.

Answer 4

Bakerloo line all the way, give it 15-20 mins to be safe
