It was a voyage into the unknown this week for a brave band of travellers who dared to ride the mysterious Ealing 'ghost bus'.
Members of Ealing Passenger Transport User Group made the journey, along with journalists from the national press and a local councillor.
They were seeing first hand what a trip was like aboard a vehicle which allows the government to dodge consultation on a scrapped west London train service and costs £500 per day to run.
The once-weekly rail replacement bus provoked criticism following reports it is not advertised anywhere at the station and regularly runs without passengers.
Jon Ball, the Liberal Democrat parliamentary candidate for Ealing Central and Acton, was among those making the trip to south London.
Perhaps unsurprisingly the bus trundled into the stop about 20 minutes late.
But the Ealing Common Councillor said: "It was a very pleasant journey, but everyone abroad was there either as a member of the press or a curious party. There was not one passenger who was actually using it as replacement for a train service.
"This simply serves to highlight the smokescreen that the government has put up to avoid a consultation. This service costs people £500 a day but very little is being done about it."
Mr Ball said he would be pursuing the matter with the help of Liberal Democrat MPs.
Until December 14, Crosscountry ran two trains a day between Birmingham and Brighton via Ealing Broadway and sections of track in west London.
The coach is a 70 minute journey via Kensington Olympia before terminating in Wandsworth Road and making the return trip.
A spokesman for the Department for Transport said that the line was being monitored and the DfT is currently looking at the best way of meeting passenger demand, which may result in more regular local rail services.
He added that passengers have been using the replacement bus service.
