How will you connect the role of railways in deforestation with transport?

Correct answer: Railway networks needed tracks sleepers and construction material

The direct answer is D: railway networks needed tracks, sleepers and construction material. Railways were not separate from colonial resource use; they expanded transport and increased the demand for timber and land. The reasoning is: first, railway lines required iron rails, but they also needed wooden sleepers to support the rails; second, stations, bridges and other railway works needed construction materials; third, forests were cleared to lay lines and obtain timber; therefore railway expansion contributed to deforestation. Option A is wrong because railways did not save every tree; expansion often involved cutting trees. Option B is wrong because railways run on land, not only on water. Option C is wrong because railways were closely connected with colonial trade, administration and resource extraction. Option D is correct because it identifies the actual material needs of railway expansion. The effect was not only the number of sleepers: land clearance and access to forests also made further extraction easier. Memory cue: railway expansion means rails, sleepers, land and timber demand.
