Island express belong to SWR. It is running 200 km in SWR & balance 715 kms in SR. So, SWR can tell SR to run this train and divert SBC cape exp via MAQ, SRR, ERN. Distance will increase by 130 kms but SR canl not raise any objections as the train will run 700 km in SR. Also, no parking problem at MAQ. SWR will be happy to do so, as they are serving more in neighbouring zone. MAQ SBC travellers get a train. New connectivity.
Win win win for all - SWR, SR, public.!!!
