Around 1935, Latvian narrow-gauge railways consisted of 536 km (335 miles) of 600 mm (1 ft 11+5⁄8 in) gauge, 432 km (270 miles) of 750 mm (2 ft 5+1⁄2 in) gauge, and 48 km (30 miles) of meter gauge.
[1][2] One public, one museum, and some industrial peat railways survive.
Track gauges were 750 mm (2 ft 5+1⁄2 in) gauge unless otherwise specified.
The peat companies mainly use 750 mm (2 ft 5+1⁄2 in) gauge, but there also exists 700 mm (2 ft 3+9⁄16 in) and 600 mm (1 ft 11+5⁄8 in) gauge railways.
