Urban trains (proastiakos) from Athens or Piraeus to the Athens International Airport and the Athens-Thessaloniki intercity line will run on a very reduced schedule on Wednesday, Greece's national railway operator TrainOSE announced on Tuesday.

Other lines affected are:

- Piraeus-Kiato-Piraeus

- Athens-Chalkida-Athens

- Thessaloniki-Larissa-Thessaloniki

All the these itineraries are affected by the nationwide 24hr general strike held by the country's umbrella unions ADEDY and GSEE.
