The commuter's dilemma.

German police are warning rail travellers to be wary when using Deutsche Bahn's automatic ticket machines because criminals attempting to break into them may have left them filled with explosive gas.

The Hesse state police spokesman, Udo Bühler, said since April criminals had successfully blown open 10 ticket machines by taping closed all holes, filling them with gas and igniting it. They then stole the money and blank train tickets inside.

But in six cases the attempts have failed, leaving the explosive gas inside, most recently on Tuesday in a train station in the town of Karben, near Frankfurt. Bühler warned that the gas could potentially ignite when an unsuspecting customer used the machine, though so far it had not.

He said incidents had also been reported in the neighbouring states of Thuringia and Lower Saxony.

The guy has got it wrong - it's not criminals, it's Greeks trying to get another bail-out.

And taping up the openings, then exploding the gas inside? I would have thought the path of least resistance would be through the taped-up openings, thus negating this method of opening the metal casing. Or is the duct-tape adhesive stronger than pressed-steel casing?

We should try it on an ATM (the bank kind).
