It is indeed unfortunate for them... Having now read the article in Rail (and having used GX in the 73, 460 and 442 days), I have to agree with much of what is said. The 442s are vastly inferior to the 460s in almost every respect - space for luggage, ease of access, height of floor, comfort, etc. And of course Brighton-London trains already well loaded with commuters stop at Gatwick and its very dificult for passengers with luggage to get on the trains. Airports need differently configured trains to commuter services - much more lugggage space, wider doors, aisles, etc. whereas commuter trains should be in maximum density configuration. There was no point in sending the 460s to Brighton because they didn't seat enough folks to use on those services, and whilst the 460s would have been no good for Brighton the 442s are hopeless for Gatwick. So like it or not, busy airports like Gatwick and Heathrow need dedicated services with dedicated stock. Its very sad that DfT haven't taken a total transport view - including the requirement of plane and train passengers - but instead have gone for a solution that favours commuters but does no favours for air passengers. For a GOOD airport service, you need look no further than HEX - quick journey, trains configured with wide doors and plenty of luggage space, dedicated service so that passengers boarding at Heathrow don't have to try to push onto trains already well loaded with punters coming from elsewhere (the only issue I have with HEX is the fare, but that's a different debate). That's how it should be done, and that's what the expanding Gatwick needs back (in respect of Heathrow, the only thing that should be done is get rid of those rediculous Heathrow Connect trains that clog the place up and serve no useful purpose - if travelers want a slower cheaper service they should be directed to the tube)
