Another travel related failure...
More than 600 of the 700 ticket machines refused to work after they were updated from a central server overnight. An unnamed Swiss company was updating the database (probably for fare calculation) when the machines began failing. It took until 1 pm for the error to be fixed on all machines.
In the meantime, security people walked around encouraging people to just get on the trains. The ticket checkers (who travel undercover and announce ticket controls just after the doors close) were pulled from the subway and put on bus and tram duty.
Last February, Boston subway fare collection machines went down, but for completely different reasons. In that case, an overloaded system seemed to cause the failure.
