I have been living in London for many years yet I still can't figure out when I am not allowed to use my Oyster card and I have to ask every time I suspect that it can't be used.
Two recent examples:
- Trains from Paddington to Slough for example stop at Ealing Broadway, Southall, Hayes & Harlington, West Drayton and Langley
I know for sure that I can use my Oyster to go to Ealing Broadway as I have done it hundreds of times and I am very sure that I cant use it to go to Slough. I cant remember which of the rest of stations are within the coverage of the Oyster card. There are no signs at the station to explain that.
- Trains from St Pancras to Ebbsfleet
If I remember correctly I can get off at Stratford, no problem using the Oyster card but you have to buy a ticket if you are going to Ebbsfleet
Again no signs and no way to tell not even the ticket machine warns you about that.
Is there something I am not aware of?
