Final answer:
A probable reason for assigning trackmen to snow removal is due to the exceptionally cold winter.
Step-by-step explanation:
A probable reason for assigning trackmen to snow removal is because the winter is exceptionally cold. During harsh winter conditions, snow removal becomes a necessity to keep transportation networks functioning efficiently.
Trackmen, who are responsible for maintaining and repairing railway tracks, may be assigned to snow removal to ensure safe and uninterrupted train operations.
In regions with heavy snowfall, railway tracks can get covered with snow, making it challenging for trains to operate. By assigning trackmen to remove snow, the tracks can be cleared, enabling trains to run smoothly. Trackmen may use specialized equipment like snowplows or shovels to clear the tracks and ensure the safety and regularity of train services.
