Thanks for your email.
I am well aware of the issues customers face each day and use the trains myself every day. When things go wrong I try and assist on stations so I feel I am as aware of the issues we face as I can be.
This morning our trains were bought to a stand while someone was removed from the railway by the police. This is frustrating for us. We have subsequently had a signalling system hit by lightening as have a number of other rail routes into London.
I share your view reliability just isn't good enough right now and this is primarily but not exclusively an issue with Network Rail reliability and we are applying pressure for improvement.
