 The certificate is issued when delays as little as five minutes occur, and even for instances where the delay is caused by circumstances beyond the railway company's control (e.g.foul weather, person under train).Handwritten certificates or printouts given out (generally in 10 × 15 cm strips) by conductors or station staff can be collected by passengers affected by lateness or delay, who can then produce it to their superiors at school or work and considered as a valid reason for reporting late.
