London Midland has agreed to accept Oyster cards on train services between Watford Junction and London Euston.
In a statement received by The Watford Observer this afternoon, the train operator said: "London Midland is pleased to confirm that Oyster Pay As You Go (PAYG) can be used on its services between Watford Junction and London Euston and all intermediate stations from this Sunday (November 18th).
"An agreement reached with Transport for London (TfL) means that the smartcards' will now be accepted between Watford Junction and Euston and stations in between those destinations from that date."
The decision followed campaigning by commuters, The Watford Observer, Watford MP Claire Ward and representatives of other political parties in the area.
On Thursday London Midland retracted a similar decision but it is thought that this one is final.
Miss Ward said: "I am delighted with the decision. It is a sensible arrangement. I think that pressure exerted early on showed that we in Watford were not prepared to put with the nonsense of only being able to use Oyster on some services.
"Hopefully now people will get the savings and service that they deserve."
