The Manila Railroad Company started to construct the Aringay to Baguio Line in 1911. Unprecedented rains caused delays and financial difficulties. World War I caused European suppliers to default deliveries of vital railroad equipment. Only 12 kilometers were built and in December, 1914 work on the line ceased.

Historians noted that MRR built railroad tunnels along the line. The Aringay-Baguio line was the second attempt to build a railroad track to Baguio.
The first attempt to construct a railroad track to Baguio started in the early 20th century and the San Fabian-Camp One line was opened to public on March, 1908. The line was also abandoned in 1914 but was reconstructed up to Binday in 1937. Download San Fabian-Camp One Line here.
The lines can be best viewed together with the Dagupan-San Fernando (La Union) line. Dagupan-San Fernando (La Union) line can be downloaded here.
