Some pictures taken by the late Michael Cleary. Late 1987 I believe. Red Rover of Aylesbury were clearly operating some services in Milton Keynes.
This is an historic picture as it actually shows a bus using Milton Keynes Bus Station. This place is now out of use, but is, believe it or not, a 'listed' building so cannot be demolished. Whilst infinitely better than just about any other bus station erected in this era, it was an afterthought and located in a pretty useless location. Though as the whole wretched city is laid out for the convenience of cars, not people, probably nowhere would be convenient. Following deregulation it was abandoned by commercial bus services!
Why am I not surprised that there is a car obstructing the stop.
