This railway existed mainly on paper, and there were no cars or locomotives lettered "Canadian Northern Pacific".
Originally, the plan was to build the rail line from Victoria to Port Alberni for passenger and freight service.
The Pat Bay line started construction in 1913 and was completed in 1916, and by 1917 the Patricia subsidiary from Victoria was opened for passenger service.
Sometime that year, the Victoria and Sidney Railway and CNoP were linked at Bazan Bay.
That same year passenger services ended on the Pat bay line, but freight continued.
Construction continued through up island and by the spring of 1924 the tracks had reached the east end of Cowichan Lake.
By 1928, the track reached Kissinger, but the plan to continue to Port Alberni had been abandoned.
In 1990, the final surviving tracks were abandoned, completely removing Vancouver Island's second railway.
That was not the end of the route, and soon it was revamped for pedestrian and cycling use and is now known as the Galloping Goose Trail.
