 Plans have been made that would either double or triple the frequency on all the services on the existing commuter rail network . However , increased frequency south of Sandnes will require double track . Should the frequency be doubled , double track would have to be built to where the current service to Nærbø terminates . Plans call for these trains to possibly be extended to either <unk> or <unk> . Should the frequency be tripled , double track would be needed all the way to Egersund . Parts of the Jæren Line is straight enough to permit speeds between 200 and 250 kilometers per hour ( 120 and 160 mph ) . However , several shorter parts need to be rebuilt to allow this , particularly between Egersund and Ogna , and from Bryne to Ganddal . In particular , the section from Ogna to Egersund would probably have to follow an all @-@ new route , should it be rebuilt to double track . The effect of higher maximum speeds is greatest for intercity trains , as the commuter trains have so frequent stops they have little to gain from the increased speeds .
