Thank you for your question, I am sorry for the disruption you have suffered.
I am afraid we have been hit by a series of events, some of which are unrelated to each other. You may have seen the letter we gave out last week which covers the details - it is also on our website.
The letter also details our plans and the investments we are making to improve the position, but ultimately, we need to significantly increase the amount of maintenance and renewal work on the track and key systems, which are intensively used and sometimes very old.
The challenge is how to do this whilst keeping the railway running safely, every day.
Everything possible is being done. I am frustrated we are in this position, but my team and I are working literally 24/7 to repair the network as quickly as possible.
