Is it possible to travel from GLQ to SIN by taking the west highland service to DMR then go from DMR to SIN (and the same in the other direction). A few guards have said that it's not possible but the scotrail app and train line both show this as a valid route.
I've booked an advance ticket from SIN to DEE and I have two seat reservations one for GLQ to DEE and another from DMR to GLQ
