Explanations:
Sikkim is a state located in the northeastern part of India, known for its rugged mountainous terrain and rich biodiversity. The state is surrounded by Nepal to the west, Bhutan to the east, and Tibet to the north. Due to its challenging topography, Sikkim is the only Indian state that does not have a railway line. The construction of a railway line in such a region would be extremely difficult and costly due to the steep slopes, dense forests, and the need for extensive civil engineering works such as tunnels and bridges.
The Indian Railways network is extensive and covers a vast majority of the country, but it has not been extended to Sikkim. The nearest railway station to Sikkim is the New Jalpaiguri railway station in West Bengal, which is connected to the state by roadways. The lack of a railway line in Sikkim is a result of the geographical and economic challenges associated with the construction of railway infrastructure in mountainous regions.
It is important to note that while Sikkim does not have a railway line, it is well-connected by roadways. The state has a network of roads that connect it to other parts of India, including the Siliguri Corridor in West Bengal, which serves as a vital link to the rest of the country. The state government and the Indian government have considered the possibility of constructing a railway line in Sikkim, but the high costs and technical challenges have so far prevented this from happening.
Understanding the geographical and infrastructural aspects of Indian states is crucial for students preparing for competitive examinations such as the UPSC, SSC, and state PSC exams. These exams often include questions about the geographical features, infrastructure, and other important facts about Indian states. Sikkim's unique status as the only state without a railway line is a notable fact that can be useful in answering such questions.
