Monsoons present some other challenges too like landslides in Ghat sections and tracks being flooded. But still it's my observation that Railway staff is more alert in the monsoons coz they know the dangers and kudos ЁЯСП to the low level staff who work pretty hard in heavy rains and thunderstorms to keep us safe.
Also i see SWR undertaking precautionary maintenance works before monsoons in Ghat sections, bridges and other vulnerable sections. I'm sure all other zones do it too.
