Maine Narrow Gauge Maximum Speeds — Speed Limits on Heritage and Regional Lines

Maine narrow gauge maximum speeds map. Colour-coded speed limits across heritage, tourist and regional narrow gauge rail lines.

Maine maximum permitted operating speeds across the narrow gauge railway network. Narrow gauge lines typically operate at lower speeds than standard gauge equivalents — most heritage and tourist railways operate at 30–60 km/h, while modern narrow gauge regional railways can reach 100–130 km/h. Slower speeds indicate heritage or tourist operations where journey experience is the priority; higher speeds suggest functional regional or commuter narrow gauge services.
