On the Class 769s, I think you have summarised the options to address late delivery. However, we very much hope the trains will be into production and further delay can be avoided.
We remain in regular dialogue with Porterbrook and the supply chain to ensure the Class 769 programme risk is minimised.
There has, at last, been diesel testing of one of the Northern Class 769s:
https://flic.kr/p/2hFw5GHApparently the first Northen class 769 was accepted into traffic today. It has run 1500 mile fault free on diesel reaching speeds of 100 mph. It will enter passenger traffic in Q1 2020.
I wonder how long until the first class 769 arrives at Reading?
