They look like the testing diagrams we should have been driving from 30th July 2018. The idea is/was to run an intensive service to prove everything worked, plus to allow training for station staff, etc. The new date we have been given to run this service is April 2019, however, we have also just started hearing rumours about this new 2020 date. I guess if we don't start in April, that will be an indication as to the project being pushed back further. In the meantime some drivers are carrying out the dynamic testing on both sides, and other drivers are learning the route out to the West so everything else is carrying on in the background.
