The line and stations were to be leased to Hertfordshire County Council who would run a tram-train service from Watford Junction to . Longer-term proposals envisaged extension into St Albans city centre, possibly to St Albans City railway station. It was estimated that the tram line would be in operation by 2012, but the project was cancelled due to the complications and expense of transferring the line from National Rail to the county council. For the foreseeable future, Watford North will continue to be served by heavy rail trains.
