When am I entitled to an overnight stay and will I be reimbursed for the costs?
If an overnight stay is necessary due to a cancellation of a train or a delay, or if it is unreasonable to expect you to continue your journey on the same day, you will be reimbursed reasonable accommodation costs.
The prerequisite is that the railway company does not provide overnight accommodation and you are unable to contact the railway company for reasons for which the railway company is responsible (contacting the DB sales office, DB Information counter or staff on the train used).
If the railway company provides you with overnight accommodation, this will take precedence over any self-organised alternative. Should you nevertheless organise your own overnight accommodation in this case, you will not be entitled to reimbursement of the costs incurred.
