What I don't want to see though is the pressure to keep to time put unduly on to front line staff. There's a danger there of promoting punctuality ahead of safety.
... and ahead of passenger service? Especially those needing assisted travel.
I have not seen evidence of punctuality ahead of safety or heard of it in recent years. But, agreed, it is something to be mindful of with future metrics.
As it stands today, if there is the slightest concern with the state of train, track, or staff a train is cancelled, and the only "races" are for quick turn arounds and station duties to make up time loss. I can't recall being on a late train that's speeding along to the extent that the ride feels more bouncy than normal.
Not easy for me to comment beyond what I have read here on assisted travel. "Ahead of Passenger service" I would suggest that at times we have a problem with
connections - many's the time I've had a train which should have connected pull out within site - dumping what is at times a not-inconsiderable number of people for a not-inconsiderable number of minutes. There will always be times a decision has to be made to avoid knock on delays, but personally I would prefer a robust timetable and a reliable service even if it means a few more minutes in the schedule. Psychologically, that may be best achieved by running trains a little below top speed between stations.
