458503 passed through Staines all very shiny and blue. Probably not so shiny on the inside...
Quite frankly I think they are dreadful trains. Certainly not a patch on the German engineering from a passenger point of view.
They just seem to be uncared for trains inside - the dirty floors, the scruffy toilets, it is frankly a disgrace that the ex-Gatwick units didn't receive any clean up in the toilets when the attention to the rest of the interior has been good. Carpet like the 450s would have been nice if they are eventually find their way back onto Reading services.
