Speculating ... bag left on a seat 'reserved from Reading'??
Or passenger in toilet?
Or listening to whatever on headphones?
Stiill left wondering about why the bag's in any Coach alone- definitely a security risk- 'See it; say it; sorted' in action. Thank you to those seeking to keep us (me) safe.
I wonder what the rules are. I've had bags removed twice, but fortunately not taken off the train.
A good few years ago I was travelling with a colleague, both of us with bags, south from Waverley, and once the train moved off we both left our bags to mark our seats and headed for the restaurant-car (as one did). Back in due course to find bags moved, seats given to others. All quickly sorted by very apologetic guard — but certainly an unpleasant surprise to come back and find things as though we'd never been there (as in some sort of detective novel).
Much more annoying and much more recent when travelling on East Midland Trains from London to Sheffield with just a very small bag, book, newspaper, etc. Seated near end of lightly-load first open. After Derby went to the adjacent toilet (so the "Occupied" light in the vehicle I was in would have come on). I returned not many minutes later to find my table had been cleared — no warning and no notification. On asking another passenger several bays away what was going on, they said the conductor had simply cleared things. So at least I knew where to hear to ask what had happened (no thanks to the railway staff), and I was duly told that the apparently unaccompanied property was a security risk and had therefore been removed.
If one is a lone traveller, without a comrade to leave in the seats, is it now safe to go and use a toilet on a train, let alone go and join a slow-moving queue in a buffet-car?
