Yeah Sky won't get those "full fat" versions due to the routes, some very tight sections. Especially a turn in Chiswick, which is mega tight.
They have some god awful Merc Sprinter conversions for the site route, only sit 16, they look crap. Apparently they are temporary for now, be interesting to see what they are replaced with.
Sky's shuttle bus service is now proving very popular, its got 3 routes.
S1 - Goes around all the main site and various rented offices we have in the area & finishes at Piccadilly Line Tube at Osterley.
S2 - Heads to Gunnersbury (District & London Overground), Chiswick Park (District) & finally Acton Town on Piccadilly line. This is the one I use, as I walk home from there.
S3 - Heads to Ealing Broadway (Paddington Mainline & Central Line) also goes past South Ealing on Piccadilly Line too.
First started out as just a handful of Mini buses, passenger numbers have been growing quickly. Its a great free service, each service runs every 15 minutes in the morning. Stops for lunch, but covers afternoon and evening right up to 9PM
