High Barnet station
I visited High Barnet on the Northern line in June 2019, and the station is very accessible. There is a raised level platform at parts of the train which allows step-free access for any type of vehicle, wheelchairs and the like. This was the second carriage from the front on arriving at the station. This appears to be a trend which I will now check for.

There are a number of ramps, this one is to exit the station.

The outside of the station has a moderate slope, maybe worse, and there are parking restrictions. I am not sure whether these are enforced.

Level access between street and platform. TFL give this a blue badge symbol. It is not bad.
