Don't walk":fihbtlb2 said:I think the circle line should let you take a bike on the train as it doesn't go below ground. I used it a couple of years ago, not sure if they've changed the rules on it or not though.
Any of the "sub-surface" routes (Met, Circle, District, Hammersmith & City) are OK for bikes outside of peak hours. Alternatively, depending on how much Thameslink engineering work has mucked things about, go Waterloo-Waterloo East-London Bridge-St. Pancras (Thameslink platforms) then walk round to KX. Sounds convoluted but works fine in practice; less crowded than the Underground too.
