There are two separate (albeit inexorably linked) issues to look at.
Firstly, you have First who have consistently failed to deliver with FDC. Wave after wave of ill considered cuts allied to a failure to invest reflected a business that had unrealistic internal ROCE hurdles and profit expectations. That is what led Mark H to set up WGL. Territory was vacated with areas such as Newquay and St Austell being ceded to WG.
That was the old mantra but in recent years, First have managed to stem those reverses in the main, regaining work around Helston and Penwith whilst winning the Truro P&R and now benefiting from Falmouth University. Nonetheless, the years of neglect have left a very old fleet of Olympians and ex London Tridents, with the only newish kit being middle aged ex Manc B7s, a few Darts and the remnants of the good stuff inherited with Truronian. They have stabilised and are turning the corner but clearly have a long way to go.
WG benefited from First's mismanagement, exploiting opportunities and developing a business that was a byword in how to operate in thin territory. However, the high standards that I had come to expect had slipped by the time I last visited at New Year. The causes are many, from losing key staff through to two fires. Also, a resurgent First and reduced BSOG/ENCTS remuneration have affected margins at a time when DDA looms large. Not only have newer vehicles gone to be replaced by tired MPDs, the condition of vehicles is markedly worse than just a couple of years before.
In truth, the gap between WG and First has narrowed. There is a lot to commend WG for but it has clearly got some issues. My wish, as an observer and sometime consumer, is that I hope WG regain their previous high standards and that First continue their improvement and begin to invest in improving the fleet profile so that the travelling public get the benefit of two good providers.
