CLEAN: France fights to keep high-speed trains snow-proof

The video discusses the impact of ballast on trains, particularly when snow causes agglomerates that can damage train windows. It explains how snow can penetrate TGV engines, posing electrical risks, and highlights preventive measures to stop snow from entering.

What is the primary function of ballast on railway tracks?

• To prevent snow from accumulating

• To absorb noise from the trains

• To hold the tracks in place

• To provide a smooth surface for trains

What is the effect of snow clusters on the ballast?

• They cause the ballast to shift

• They make the ballast more stable

• They dissolve the ballast

• They form aggregates between the stones

What happens when trains pass each other at high speeds with snow clusters present?

• The snow clusters create a loud noise

• The snow clusters melt instantly

• The snow clusters can damage the train windows

• The snow clusters fall off the tracks

How does snow pose a risk to the TGV engine?

• It poses an electrical risk

• It increases fuel consumption

• It slows down the train

• It causes the engine to overheat

What measure is mentioned to prevent snow from entering the TGV engine?

• Applying anti-snow chemicals

• Using protective curtains

• Installing snow guards

• Using heated tracks
