Bad health of railway drivers lead to train accidents

As many as 25 small or big train accidents that took place in the recent past were due to what the loco running staff in the Indian railways term as ‘micro-slipping effect’. This has been established by a study conducted in Germany and Japan.
Micro-slipping effect is a phenomenon in which the drivers of trains have a wink or some sort of a 'nap attack' for two second to 30 Seconds, due to lack of proper rest.
There had been a spurt of such cases wherein loco pilots happened to miss signals or apply brakes in time, thus leading to accidents. World famous Waterfall train Accident near Sidney (Australia) caused due to Micro-Sleep.
This, he said, clearly indicated the safety hazards in rail journeys stemming from loco pilot's health which the railway authorities have long been ignoring. "Owing to lack of proper rest and less number of sleeping hours, the drivers become more susceptible to causing accidents. Nearly 10 of such incidents have taken place in the South Eastern Railways.

"The erratic work hours are taking a toll on the health of loco pilots. A driver needs to rest properly so that he is vigilant when on duty. At least once in two nights he needs to have sleep at night as the day's sleep cannot provide the same kind of relief.
On the contrary, it has been found that most of the loco pilots drive long distances, sometimes without getting proper rest for consecutive nights.
"The railways are treating its loco pilots as machines. According to a survey conducted by Nagpur-based Labour Institute, health deterioration was found in up to 30 per cent of 300 loco pilots covered in the survey. This is a cause for concern for all, whether it's the loco pilots, the railway authorities or the passengers. Therefore, railways must do something in this regard.

  1. Micro Sleep the reason of train accident attributed to human failure on administrative account. I mean to say that micro sleep disease attacking on running staff's health due to the administrative lapses only such as non granting of PR, continuous night (Graveyard shift)working, not granting of leave, inadequate facilities at Running Room, lack of interest of enquiry committee's towards the route cause of accident & suggestion to prevent it. Enquiry committee's are interested only in fixing the responsibility upon the running staff based on the violation of outdated rules instead of going in deep.
