Renfe minute

A Renfe Minute is the amount of time you wait for a (Renfe) train in Spain to arrive as the digital display counts down some made-up number.

I arrived at the station and the display said that the train was only a minute away. It said that for the next 7 minutes.

It's called a Renfe minute and that's why I hate public transport, you never know when the train will actually arrive.
