Passengers must be kept informed of the situation by the railway undertaking or by the station manager including current estimated departure and arrival times as soon as such information is available.
In the case of delays over 60 minutes, the passenger shall be offered free of charge:
meals and refreshments in reasonable relation to the waiting time if these are available on the train or station or can be reasonably[footnote 1] supplied
hotel or other accommodation and transport between the station and the accommodation in cases where a stay of one or more nights becomes necessary, when physically possible
transport from the train to the station if the train is blocked on the track, to an alternative departure point or the final destination of the service, where physically possible
Where the railway service cannot be provided, the railway undertakings shall provide alternative transport as soon as possible.
Where there is disruption, the railway undertaking shall certify the same on the ticket when requested by the passenger.
When discharging these duties, the railway undertaking shall pay particular attention to the needs of people with a disability and others with reduced mobility.

10. A railway undertaking shall not be obliged to pay compensation if it can prove that the delay, missed connection or cancellation was caused directly by, or was inherently linked with:
(a)
extraordinary circumstances not connected with the operation of the railway, such as extreme weather conditions, major natural disasters or major public health crises, which the railway undertaking, in spite of having taken the care required in the particular circumstances of the case, was unable to avoid and the consequences of which it was unable to prevent;
(b)
fault on the part of the passenger; or
(c)
the behaviour of a third party which the railway undertaking, in spite of having taken the care required in the particular circumstances of the case, was unable to avoid and the consequences of which it was unable to prevent, such as persons on the track, cable theft, on-board emergencies, law enforcement activities, sabotage or terrorism.
Strikes by the personnel of the railway undertaking, acts or omissions by another undertaking using the same railway infrastructure and acts or omissions of the infrastructure and station managers are not covered by the exemption referred to in point (c) of the first subparagraph
