Thank you Davy - that's nearly perfect and very helpful!The PDF of taking a bicycle on Tube map is a good start
I think only major thing I can see from that that aren’t Tube tunnels is the Piccadilly line between Hounslow West and Hatton Cross which is twin track tunnel (with a short above ground section for the crane bank). Obviously you also have bits like Bounds Green <> Oakwood where bikes aren’t permitted due to the tunnel at Southgate, but most of the aforementioned section is above ground. SThank you Davy - that's nearly perfect and very helpful!
Doesn’t make a distinction between covered ways, Sub surface and Tube tunnels however.Also on the TfL website is this map: https://content.tfl.gov.uk/tube-map-with-tunnels.pdf

People who are anxious about travelling in tunnels perhaps ?Who is that aimed at?

Thanks, that makes sensePeople who would like to connect to a mobile signal en route.
Similarly, there are notices inside Piccadilly line trains to advise air passengers which parts of the route to Heathrow are appropriate for checking the status of their flight.
The map pre-dates that project, and it's worth keeping around for anyone who might find it useful for other reasons (even if they would not justify the work to create one from scratch).Yes, though full 4g signal is available in much of the Jubilee's tunnel sections.
Waterloo and City?Hello, I'm seeking a map showing only the deep tube tunnels (the underground portions of Victoria, Central, Bakerloo, Piccadilly, Jubilee, Northern), without the aboveground portions of those lines and without any subsurface lines?
There really is not much difference at all once the doors are closed and one is inside a carriage with other passengers. Even if it's a hot day and the end windows are open, the aerodynamics of the tunnels tend to force more of a breeze than when 'outside'.Thanks everyone for your helpful suggestions. In case you are interested, I asked because I just hired my first employee to move to London and work for me. I have told him he can take taxis at my expense to avoid the deep tube lines until he gets vaccinated for covid, under the assumption their poor ventilation makes them at least somewhat more risky than other lines (debatable). He doesn't know London, so he asked where the policy applies, hence my question to you all. I think Davy Crocket's bike map is very close to what I need, and I can easily explain the exceptions to my employee. Wolfie correctly pointed out I overlooked Waterloo & City, and it could be argued my policy should also apply to the Northern City Line. If anyone can think of any other underground rail around London with comparably poor ventilation, I'd be interested in hearing. Thanks again!
I'd argue that what you notice shows that air exchange between train interior and tunnel is very effective. The volume of the tunnels & stations is such that the viral load will be insignificant in the tunnels (far more harmful is the usual brake dust/etc in the tunnels)I agree it's debatable how big the difference is. My clients are located all over London so I have travelled much of the tube system for work over the past 20 years. I have noticed that the air quality (subjective "freshness") inside the deep tube carriages improves very noticeably immediately after the carriages exit tunnels to open air, but I haven't noticed the same effect on the subsurface lines. Therefore I assume (unscientificaly) that the airborne viral concentration is somewhat higher in the deep tunnels.
