Many lines have had one or two trains cancelled - that's all. For most users the greatest inconvenience would be another few minutes to wait or taking a train a few minutes earlier.
If you look at the timetables you will find that there are gaps created of up to one hour from these cancellations. The cancellations should have been more properly planned rather than just looking at operational convenience. It would make more sense to cancel short workings that often run with light loads and have trains run the full distance and pick up at a few more stops.
