[SystemSafety] Watch out for exploding ticket machines on German Railways!!

What I want to know is does the risk appear on the hazard analysis for
ticket machines; that is assuming of course that there is (or was) a hazard
analysis...

> just when we travelers thought DB had the user interfaces finally sorted
out...

Don't get me started on interfaces, BT have just updated the software for
their set top boxes and in the last two days I've spent nearly two hours on
the phone explaining why the new menu's don't scale from 3 recording of CSI
which will be deleted, to 50+ recording of Octonauts (1) which will be kept
until both Thing #1 and Thing #2 get sick of them or Hell (2) goes sub-zero.

Cheers.

Well, just when we travellers thought DB had the user interfaces finally
sorted out...... Unless, of course, they only explode when naughty people
try to buy tickets.......
