I have only been on the tube a couple of times since I started to use a wheelchair. There is an underground map that shows which tube stations are wheelchair accessible. We planned to use a Baker Street station, which was on this map, but with an exclamation mark next to it. We bought tickets, went through the barrier, looked for the lift and couldn’t see it. We asked the grumpy attendant where the lift was and he said “there isn’t one, you can take the wheelchair on the escalator”.
My husband and I didn’t have the nerve to do it, so the grumpy attendant took me down the very long escalator. We went down backwards, with him behind me, looking over his shoulder all the time and when we got to the bottom, he whisked me off. He then did the same thing down another very long escalator. It was actually quite exciting, being taken by someone who knew what he was doing and was really used to the escalators but it would have been scary and possibly dangerous with a novice. At the bottom, the guy took me onto the platform and showed me where there was a raised bit so that I could wheel straight onto the tube train. Most of the platform was a few inches lower than the edge of the train.
We travelled to Waterloo or somewhere like that, which is on a newer bit of the line. It was very easy at that end. It was properly accessible, at least to a wheelchair user, with all the platform level with the edge of the train and a good lift. I don’t know how easily a big scooter would fit onto the tube.
When we came back, my husband brought me up the escalator, which was fine, because he was facing in the direction of travel.
Sorry not to be able to provide a more encouraging story. I will use the tube again in a wheelchair but I would be nervous of doing it on anything other than a very small scooter. I’d make sure I read the small print on the disability access tube map, as well. I hope someone else can describe a better experience.
