The railways and (slightly less so) the Tube are missing a trick with
newspapers, free or otherwise, in that they get picked up as rubbish.
Why not put a clearly-signed plastic newspaper rack in each vestibule
(perhaps facing the seats on the Tube so it doesn't get in the way of
standing passengers) and encourage passengers by way of notices and
announcements to leave any unused newspapers in the rack for another
person to read?

Tidier, more environmentally-friendly, good passenger service and would
cost next to nothing.

When they collect them now do they recycle them?

What is shocking is that certain stations have already run out of
Metros by 8am. I think it tends to be the ones that have newspaper
sellers in the station because they can't bear the competition.

That means that passengers scrounge around for them, any leftover ones
on the train, on the platforms, even in the bins (which they do have).

There is already a place to put finished-with metros - when you leave
the station just put it back into the metro stand.

Note: I once took a pile of metros with me on the way from Brent Cross
(where there are loads) to Finchley Road (which is out of them before
8am) and put them into the stand there (apart from the one I wanted for
myself) and they were gone within seconds.
