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.

How does 5G work?
5G networks divide coverage areas into smaller zones called cells, enabling devices to connect to local base stations via radio. Each station connects to the broader telephone network and the Internet through high-speed optical fiber or wireless backhaul.
How does a 5G base station work?
The 5G Base Station uses a set of antennas that connect with the distributed unit. These antennas can be implemented using a passive or active architecture. These are connected to the Base Station cabinet using feeder cables. The Base Station cabinet includes the transceiver and RF processing functions.
What's the difference between 3GPP 'Option 2' and 'base station' architectures?
These names originate from the 3GPP study of 5G radio access technologies documented within 3GPP Technical Report 38.801. Both architectures have Base Stations that connect to the 5G Core Network. The 'option 2' architecture is based on a gNode B connected to the 5G Core Network.
What are the goals of 5G?
Finally, one of the key aspirational goals of 5G is the ability to segregate traffic for different usage domains into isolated network slices, each of which delivers a different level of service to a collection of devices and applications.
