Timeline of African Union of Railways

According to Railway Gazette International of November 2007, East Africa (TZ, KE, ET and UG) are proposing lines aplenty.

Triple gauge for the three main gauges in Africa are a practible solution for mixed gauge tracks.

Narrow 1,067 mm (3 ft 6 in) gauge and Metre 1,000 mm (3 ft 3+3⁄8 in) gauge are too similar (67mm) to allow third rail dual gauge.

Four rails must be used, which creates a third gauge, which may as well be 1,435 mm (4 ft 8+1⁄2 in) gauge.

This Africa rail-related article is a stub.

1000 mm and 1067 mm gauges can be combined as a 4 rail dual gauge with bonus 1435 mm gauge
Triple gauge supports the three main gauges in Africa:
Red: 1,000 mm ( 3 ft 3 + 3 ⁄ 8 in ),
Green: 1,067 mm ( 3 ft 6 in ) and
Blue: 1,435 mm ( 4 ft 8 + 1 ⁄ 2 in ).
The wide separation or the outer pairs of rails (435 mm and 368 mm) provides space for railclips and suits turnout construction.
