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).

Houston/WASHINGTON, D.C., September 26, 2025 — The U.S. energy storage market set a record for quarterly growth in Q2 2025, with 5.6 gigawatts (GW) of installations, according to the latest U.S. Energy Storage Monitor report released today by the American Clean Power Association (ACP) and Wood. .
For years, the energy storage market in the United States existed on speculation. There was plenty of discussion on the technology’s ability to improve the electrical grid but very little follow-through. The mood started to shift in the 2020s. Each quarter has a new record-breaking storage.

What are solar-powered unmanned aerial vehicles (UAVs)?
In the field of aviation, solar-powered unmanned aerial vehicles (UAVs) have attracted attention owing to their high-altitude cruise and the availability of renewable energy , .
Which energy supply system provides UAVs with energy during a cruise?
As shown in Fig. 1(a), the energy supply system, which includes photovoltaic and battery systems, provides the UAVs with energy during the cruise. The photovoltaic system contains photovoltaic arrays and a maximum power point tracker (MPPT).
How are solar-powered UAVs distributed?
Considering the actual situation in the flight process, the principle of energy distribution was used to distribute the energy inside the UAVs, and the energy distribution of solar-powered UAVs was optimized using a multi-objective genetic algorithm. A solution flow chart involving all models is shown in Fig. 7. Fig. 7. Model solving flow chart.
Are fuel cells a viable option for lightweight UAVs?
Fuel cells, particularly proton exchange membranes, demonstrate high energy density, enabling long flight durations for lightweight UAVs, yet face challenges such as slow response and hydrogen storage limitations.
