Hi,
My last cycle survey was in 2013 before the refurbishment started - might have a look again.

The separate tunnels were built and refurbished with dedicated cycle and foot use, so bicycle=dismount on the foot bore seems a bit pedantic. I'd still use the cycle tunnel with a mechanical failure just to get the better echo (used to have different floor surfaces).

Escalator and lift access is a 4+ year saga of bad contractors, bankruptcy, historical listing, and silly decisions.
The website seems to be as broken:

Happy Mapping,
