Sounds like it could get ugly.

Some TOCs are planning on running an amended timetable (East Coast,
c2c), others have one up their sleeves, ready to go (or not go, as the
case may be).

This afternoon might be a good time to go out and enjoy the splendid
autumn colours - in southern Britain at least - might not have any
autumnal leaves left on the trees come tomorrow, indeed might have fewer
trees as well.
