Turms out this one may not be a myth after all Rebbonk?
On the wall of Morrisons there's a giant photo of the Alvis factory taken from the air in 1951. On the East side of the railway, set well back from the main road, there is a collection of what appear to be very shallow flat-roofed huts or bunkers. It's not possible to tell from the angle of the photo whether these are taller buildings sunk into the ground or not. They could well be storage bunkers, wartime air-raid shelters or as you mentioned, a hospital facility of some kind?
City planning records make no mention of what was there before the current housing estate was built but that is not unusual where wartime facilities are involved.
St John Abulance Service current headquarters are very nearby, on the opposite side of Holyhead Road so there may be a connection of some kind there?
