Will the service go 7 days a week the same time as through running commences?
Yes - earlier running, through running and Sunday service all at the same time. Bond St will be open too, either on that date or before.
Although interestingly the planned works calendar stops showing the limited opening hours at the start of October.
It's the 12 week calendar I think? Next week we should see, it just happens to be almost exactly 3 months (12 weeks) away right now which is the agreed timeframe for planned engineering works into journey planners.
