The Cork Dublin Express Train has entered service

[Mark Gleeson]

If you do happen to be on a Mk4 and you hear a loud thud unlike the normal sound effects you get under the floor and you just happen to be sitting at the coach end, find and tell the train manager as it indicates a much larger problem

If the coach becomes wildly unstable after the thud, thats why they invented the communcation cord, which incidently doesn't directly apply the brakes

Passenger last week hear thud, told train manager and they stopped and found something broken
