I may be biased but I believe, the current tarka line from south Devon to north Devon could be beautifully modelled with all its quirks like the single track section where driver has to wait for the other train and pass over a key to open the track to the other train. More interesting would be if at Barnstaple this could link with the historic Lynton-Barnstaple railway with viaducts and Exmoor countryside would be a beautiful British route
