The Caledonian Railway lost no time in imposing its presence; through traffic to Glasgow and Edinburgh was routed via Lockerbie and the CR. The CR was responsible for maintaining the PPR line, but soon requested additional facilities, such as siding accommodation at Stranraer and additional crossing places. The actual intermediate passing places were New Galloway, Dromore, Creetown, Newton Stewart and Glenluce. The CR wanted to add Crossmichael, Loch Skerrow, Kirkcowan and Dunragit. The PPR had imagined that signing the Working Agreement would release it from expenses like this, and in any case hardly had any money to extend its facilities.
