This undated photo made available Thursday Jan. 17, 2019, shows the so called 'delay scarf' which a Munich commuter has knitted with each colour reflecting the amount of time her journey with Deutsche Bahn train service had been delayed. The hand-made scarf sold in an online auction for 7,550 euros (dollars 8,600) to the German Railway Deutsche Bahn. The money is being donated to a charity for the homeless. (Sara Weber via AP)
