The depot will be closing down shortly. All the VOSA cancellations have been accepted. Skem is a loss maker depot. Another local bus operator, Fairway has recently been forced to close due lack of finance. The buses don't make money around Ormskirk/Skem due to a high proportion of concessionary passes in use and the fact the bus journey times are slow (towards Liverpool/Southport).
Skelmersdale has a population approaching 40,000, with many Liverpool populace conections. I note that you make mention of both the Liverpool and Southport bus services at the end of your thread. The Arriva bus depot to which you refer was the original Ribble bus depot. All the buses that will serve Skelmersdale will now be run from depots in St. Helens, Bootle and Southport. You say that the bus journey times are slow towards Liverpool and Southport. That surely will be the result that all the buses stop at every bus stop on the route if required to do so. This will be reflected in the timetabling of such bus services. You cannot say the number of concessionery pass holders are a very large percentage of the population of the area. This paints a totally false image of both Skelmersdale and Ormskirk.
The matter of Fairway closing down is comparable to the situation that affected Bu Val in the Rochdale area, at virtually the same time. But just to mention "finance" as a blanket statement does not clarify the total number of reasons why the closures of both companies occurred.
