I visited Turnpike Lane station in July 2019. There is an elevator to exit or enter the platforms to get to the ticket hall. From the ticket hall to the various street level entrances there are a number of stairs at least 20 in number. Not an accessible station at all.
All the London railway stations :
Turnpike Lane station
Underground lines : Piccadilly
Turnpike Lane stairs to bus station
Turnpike Lane stairs to a random entrance
Accessibility friendly : No.
