Cabs, 4,9,10,11,19 and 44 are all in phase 9b which is quite alot to see after a exchange has been enabled.
Though looking at the whole of the exchange came online in phase 4a and then another round of cabs in phase 6a and now 9b certianly alot of inflling.
Of the cabs being enabled in phase 9b do you know which one it is (need to know the postcode for youre line) and where it is located?
