The National Rail Live Arrival/ Departure boards at Marylebone state that there are currently no Jubilee or Metropolitan Line services operating from the station, due to engineering week.
I have already mentioned that there is indeed much engineering work going on this weekend on the London Underground. This significantly affects most of North West London.
However, for the avoidance of doubt, the fact that the Jubilee and Metropolitan Lines are not stopping at Marylebone is not because of engineering work. Neither of those two lines ever stop at or go through Marylebone. However they do both normally serve nearby Baker Street.
Call me a pedant if you wish!
The Bakerloo Line is working normally, just be careful where you want to go.
