The correct option is
B. Africa's railway lines are all of uniform gauge. This statement is false.
Detailed Explanation:
- Understanding Railway Gauge:
-
The gauge of a railway refers to the distance between the inner sides of the two rails. Different countries and regions may use different gauges, which can affect the interoperability of railway systems.
-
Railway Gauges in Africa:
- In Africa, there is a mix of railway gauges. The most common gauges are:
- Standard Gauge (1435 mm): Used in countries like Kenya and Ethiopia for newer railway lines.
- Cape Gauge (1067 mm): Predominantly used in Southern Africa, including countries like South Africa, Zimbabwe, and Zambia.
- Narrow Gauge (often less than 1067 mm): Found in some regions, such as parts of East Africa.
-
This diversity in gauges means that not all railway lines in Africa are uniform, making option B incorrect.
-
Why the Other Options Are Correct:
-
Option A: "There is no trans-continental railway in Africa which can be compared with the Trans-Siberian Railway in length or importance."
- This statement is true. While Africa has significant railway lines, none match the Trans-Siberian Railway in terms of length or the extent of connectivity across multiple countries.
-
Option C: "Few railway lines in Africa cross from one country to another."
- This statement is also true. Many railway systems in Africa are designed primarily for domestic use, and international rail connections are limited. This is due to historical, political, and economic factors that have influenced railway development.
-
Option D: "The railway lines of Africa generally run from the coast inland."
- This statement is true as well. Many African railways were constructed to transport goods from inland resources (like minerals) to coastal ports for export. This pattern is evident in countries like South Africa, where railways connect mining regions to ports.
Common Pitfalls:
- Assuming Uniformity: A common misconception is that all railway systems in a continent will have the same gauge. This is not the case in Africa, where historical developments and colonial influences have led to a variety of gauges.
- Overlooking International Connections: Students may underestimate the limited number of international rail connections in Africa, focusing instead on the extensive networks within individual countries.
Revision Summary:
- Railway gauges in Africa are diverse, including standard, Cape, and narrow gauges.
- There are no trans-continental railways in Africa comparable to the Trans-Siberian Railway.
- Most railways in Africa serve domestic purposes, with few crossing international borders.
- Railways typically connect inland resources to coastal ports for export.
This understanding of Africa's railway systems is crucial for grasping the continent's transportation infrastructure and its economic implications.
