How did railway construction put double pressure on forests?

Correct answer: Timber was needed for sleepers and land was needed for tracks

Railway construction affected forests in two ways. Large quantities of timber were cut for railway sleepers, and forest land was cleared for tracks, stations, and related infrastructure. Therefore, option A is correct. Option B is incorrect because railways required much more than stone; timber and land were especially important. Exam tip: For ‘double pressure’, mention both timber extraction and clearing land for rail routes.
