Most of the Sofia Tramway system, except for three lines with standard gauge. When the condition of tracks vastly deteriorated during WW2, it was formally widened to 1,013 mm (3 ft 3.88 in) in order to avoid loss of the licence. Then it gradually narrowed to 1,009 mm (3 ft 3.72 in) with a tendency to be reverted back to 1,000 mm (3 ft 3 3⁄8 in). All these changes affected only the infrastructure and not the rolling stock. |
