Yes - National Express still call there. Nice little building with no obvious connection to anywhere else.
Megabus (Leicester - MK - London - Amsterdam) initially called there too, but has since relocated to Kingston Centre bus stop instead.
Comes off the M1 at J.14, A509 towards Northfield Rbt., H6 Childs Way to Fox Milne Rbt., the V11 Tongwell Street to Winchester Circle (District Centre).
From there it continutes back onto the V11 Tongwell Street to Brinklow Rbt., where it takes the A421 to J.13 of the M1, and vice-versa.
Doesn't call at Coachway as it is a National Express facility - charges for Megabus obviously weren't worth it, I imagine them being uncompetitive as they are their (Eurolines/NX) competition.
