I need to go from Kings-cross train station to Piccadilly and back.
I used to lived in London ( 1999-2010) many moons ago and to be honest I completely forgot how to even get on Tube!
Do you still use Oyster, are these still cards or now digital on the phone, do I need some deposit, How do you scan it on tube station to get in?
Im only will be going there and back to King cross to catch train back ( out of London)
What would be the fastest way on tube and also the cheapest for me?
