The combination of railways with different track gauges into a hybrid railway network requires measures to make the different railways interoperable despite the problem. In East Africa, this applies to the new standard-gauge railway network and to the old and eventually rehabilitated narrow-gauge railway network. Two methods exist within the East African Railway Master Plan countries for break of gauge handling and passenger transfers.

What is the East African railway master plan?
The East African Railway Master Plan is a proposal for rejuvenating existing railways serving Tanzania, Kenya, Uganda and extending them initially to Rwanda and Burundi and eventually, to South Sudan, Ethiopia and beyond.
Does East Africa have a rehabilitated narrow-gauge railway network?
In East Africa, this applies to the new standard-gauge railway network and to the old and eventually rehabilitated narrow-gauge railway network. Two methods exist within the East African Railway Master Plan countries for break of gauge handling and passenger transfers.
Which papers were excluded from the study of railway transport in Africa?
6. Selected papers were case studies on railway transportation in Africa or African cities. 7. Papers merely discussing the history of Africa's railway without discussing recent projects and operations were excluded. 3.2.
What is the density of the African railway network?
The geographical density of the African railway network is considerably lower than other regions and the world average of 23.1 km/1000 sq. km (African Union, 2014). The highest density is in Southern Africa (5.6 km/1000 sq. km) compared to a range of 1.2 to 2.3 km/1000 sq. km in other regions of the continent (Appendix A2).
