“Trolleys", hand-made human-powered metal handcarts operated by “trolley boys” transport people along sections of the PNR lines. This is a popular means of transport, due to it being cheap (roughly ₱10 or US$.20) and avoiding traffic. Many “trolley boys” are homeless, and live alongside the rail line as a result. Since the line is actively used by passenger trains, collisions with passenger trains are a consistent danger, although casualties are reportedly rare. Rides are unofficial and unregulated, but tolerated by authorities.
