When I last did "stats" a few days ago, we were at 10% cancellations over the previous week, with the remaining traisn typically being a few minutes late. The one train I went for (06:44 the other morning) was 15 late and would have missed my ongoing plans ... so I aborted the trip.
The trains are quiet ... but the timing is all wrong. See the front page of "Save the Train"
