My trust in our train system is such that, if I have a London trip, the very first thing I do in the morning is see whether the trains are running (on time, or at all).
Not that that can't change at any point before my train. Or while I am on it.
But, fingers crossed...
@neil I do the same thing in Melbourne. In fact I have a tablet running a Home Assistant dashboard by my front door as I come down the stairs that tells me when the next bus is scheduled, its actual ETA, and the status of the connecting train lines so I can tell whether it's even worth looking for my shoes (often, it's not)
