I'm looking to travel from Tottenham Hale to Cambridge on Saturday 31st August in the morning. However I want to return to London Liverpool Street probably Monday late afternoon/evening...
I know there is a Greater Anglia service from London Liverpool Street to Cambridge that stops at Tottenham Hale... So is it possible for me to buy an off peak return from London Liverpool Street to Cambridge, but still be able to hop on the train at Tottenham Hale on my outward journey?
I get too paranoid for my own good and don't fancy getting told off
Thank you!
