I do wonder if the comments about ride quality of 777s are being made by people who are comparing to different stock running on a different line. The best comparison would be between two different types on exactly the same line. Not sure that is possible unless restricting the comparison of 777s to 507s/508s.
Merseyrail track has historically been a bit poor. 507s would hit the stops at every rail joint in the Kirkdale tunnels, for example.
