France's national railway operator SNCF has ordered 2,000 new trains that are too large for many of the stations they are due to serve.
The train operator has admitted failing to verify measurements it was given by the rail operator before ordering its new rolling stock.
The costly mistake has sparked an urgent 50m operation to modify 1,300 platforms on the regional network. SNCF has admitted that one in six regional train stations is affected. In the worst cases it has discovered two trains can no longer pass each other on adjacent lines.
Don't you just hate it when that happens?
