Caption: CN 2448 and 5536 are westbound at Basque on CNs Ashcroft Sub. There's a two way connection here between the CN Ashcroft and CP Thompson Subs. The crossover is used regularly due to directional running (since 1999) required to and from the coast via the Thompson and Fraser Canyons. This connection / crossover is listed as a directional running boundary. Eastbound routes beyond this point split up again at Savona and run either side of Kamloops Lake.
