The rules name public company Ø as 'Østfoldsbanen' but it is spelled 'Østfoldbanen' on the company charters. Google and Wikipedia suggest the spelling without the 's' is correct.
Thank you - the correct spelling is Østfoldbanen - will correct. This spelling applies to Vestfoldbanen as well. Luckily these errors are only in the rulebook as far as I can tell.
