Step 2
Explain
Answer
High temperatures can cause the metal tracks to expand. This phenomenon is known as thermal expansion. When the temperature rises, the iron or steel rails heat up and begin to elongate. If the expansion is significant, the rails may bend or warp, leading to misalignment. This misalignment can create dangerous conditions for trains, causing derailments or accidents.
