Manganese steel is chosen for manufacturing railway tracks mainly because:

1. it is hard and contains a high percentage of Mn
2. it is soft and contains a high percentage of Mn
3. it is hard with a small amount of manganese plus impurities
4. it is soft with a small amount of manganese plus impurities

Correct answer: it is hard and contains a high percentage of Mn

Solution

Manganese steel contains a high percentage of Mn (around 12-14%) which makes it very hard and abrasion-resistant, ideal for rails.
