The previous bus wouldn't pick up two bus loads to an extent the balance would be equal.

What we possibly need through the BSIP money Is "funded" hourly express service Newcastle Gateshead Heworth Metro & Washington Galleries only

And similar scenario to assist buses getting back on track

This express service runs hourly however if there is late running of services similar to above where 2/3 buses are stuck together to push buses off to run an "extra service" of this express type

Passengers at Eldon Square can be told (via driver announcement to let to pass the message down the queue) like Chinese whispers) this bus stops only at these three stops your ticket for onward journey would be valid on a specific connecting bus of the X1 or stay on this bus for all stops to XYZ however there is a 14 min wait at the galleries but you can board the bus in front with your ticket.

All the driver would have to do is issue a ticket on the ticket machine "permit to transfer" a new special ticket to pass to a connecting service

A destination screen perhaps saying Extra bus
