The Pinallon Line or Vinylon Line is an electrified, freight-only industrial railway line of the Korean State Railway in Hamhà Âng, South Hamgyà Âng, North Korea, running from Hamhung marshalling yard to Hà Ângnam via the February 8 Vinylon Complex in Hà Ângnam.
It runs parallel to the narrow-gauge SÃ Âho Line for most of its length.
The Pinallon Line was opened by the Korean State Railway in May 1961, when the February 8 Vinylon Complex was opened, as the existing narrow-gauge SÃ Âho Line was insufficient to meet the freight-hauling requirements of the industrial complex.
With the narrow-gauge SÃ Âho Line handling the passenger traffic, primarily workers at the various industries located along the line, the Pinallon Line transports only the freight heading to and from the various industries located along the line.
These industries include:
as well as several other smaller enterprises.
A yellow background in the "Distance" box indicates that section of the line is not electrified.
