Night Duty Is Not Just Fatigue: How Irregular Shifts Are Slowly Rewriting a Loco Pilot’s Health

 Night duty is often spoken about as if it is just another shift.

“Take proper rest .”

“Sleep later.”

“Body will adapt.”

But for a loco pilot, night duty is not just loss of sleep.

It is a slow, silent rewriting of the body, mind, and life itself.

When the world sleeps, a loco pilot stays awake—not for comfort, not for choice, but for responsibility. Trains must move. Signals must be obeyed. Lives depend on alertness. And yet, the very system that demands perfection quietly pushes the human body beyond what it was designed to endure.

The Body Was Never Meant for This Clock

The human body follows a natural rhythm. Sleep at night. Wake with light. Digest during the day. Repair during rest.

Night duty breaks this rhythm again and again.

One night you report at 11 PM.

Another day at 3 AM.

Sometimes you sleep at 8 AM.

Sometimes at noon.

Sometimes not at all.

There is no “routine.”

There is only adjustment after adjustment, until the body stops asking and starts suffering.

Sleep becomes shallow. Even after 7 or 8 hours in the daytime, you wake up tired. Noise, light, family movement, heat—everything interrupts rest. Slowly, sleep loses its healing power.

What starts as fatigue becomes chronic exhaustion.


Digestive System: The First Casualty

Ask any loco pilot on irregular duty about stomach problems. The answer is almost always the same.

  • Burning sensation
  • Acidity
  • Indigestion
  • Bloating
  • Nausea
  • Loss of appetite

Food timings change daily. One day dinner at 6 PM, another day at midnight, sometimes nothing for 12 hours, then sudden heavy food.

The stomach does not understand “running duty.”

It only understands rhythm.

Over time, irregular eating combined with stress leads to gastritis, ulcers, and dependency on antacids. Many pilots live with stomach pain silently, popping tablets before duty just to stay functional.


Blood Sugar and Blood Pressure: Silent Damage

Night duty quietly interferes with hormones that control sugar and pressure.

Cortisol rises.

Insulin response weakens.

Stress becomes constant.

Many loco pilots are shocked when medical reports show:

  • Borderline diabetes
  • High BP
  • Abnormal cholesterol

They ask, “I don’t even eat much… why this?”

Because sleep deprivation itself is a disease trigger.

Even those who were fit for years suddenly find themselves on lifelong medication—not because they lived carelessly, but because their biological clock was repeatedly violated.


Mental Fatigue Is More Dangerous Than Physical Tiredness

Physical tiredness is visible. Mental fatigue is not.

A loco pilot may look normal, but inside:

  • Concentration reduces
  • Reaction time slows
  • Irritability increases
  • Anxiety builds

The mind never fully relaxes. Even on rest days, thoughts about the next call, next duty, next night disturb peace.

Family time feels incomplete. You are present, but not fully there. Children want attention when you want sleep. Spouses worry when you look withdrawn.

Slowly, emotional distance grows—not because of lack of love, but because of lack of energy to 


The Fear No One Talks About

There is a fear every loco pilot carries silently.

“What if I miss something?”

“What if my alertness drops for a second?”

“What if fatigue causes a mistake?”

This fear itself is exhausting.

Unlike many jobs, a loco pilot cannot “relax” on duty. Every signal, every sound, every speed restriction demands attention—often during the body’s lowest alert phase between 2 AM and 5 AM.

The responsibility is heavy.

The recognition is light.

And the health cost is personal.


Family Life Runs on a Different Track

While others plan weekends, festivals, and routines, a loco pilot plans sleep.

Birthdays missed.

Functions attended half-awake.

Festivals celebrated either too early or too tired.

Children slowly learn:

“Appa is sleeping.”

Spouses adjust, often silently, carrying emotional and household load alone during night duties.


This emotional strain is rarely acknowledged in service records, but it leaves marks deeper than any medical report.


What Loco Pilots Really Need

Not sympathy.

Not motivational speeches.

They need:

  • Predictable rosters
  • Adequate rest after night duty
  • Respect for circadian health
  • Honest discussion about fatigue
  • Medical policies that prevent illness, not just detect it

Most importantly, they need acknowledgment that night duty is not a normal shift—it is a health risk.


A Final Truth

A loco pilot does not complain easily.

He adjusts. He endures. He delivers.

But endurance should not be mistaken for immunity.

Night duty may not break the body in one day.

It rewrites it slowly—cell by cell, habit by habit, year by year.

And by the time the damage becomes visible, the service years are over.

If trains are the lifeline of the nation, then the health of those who drive them should never be treated as expendable.

Because behind every safely running train, there is a human being fighting sleep, stress, and silence—just to keep the wheels moving.

One Mistake, One Memo: Why Running Staff Live Under Constant Psychological Pressure

In the world of railways, millions sleep peacefully every night because someone else is wide awake—alert, focused, and carrying the weight of absolute responsibility. For running staff—loco pilots and train managers—work does not end with duty hours. It follows them home, sits beside them at the dining table, and often lies awake with them at night. This is not just a job. It is a 24×7 mental burden where one mistake, one second of human error, can invite a memo, suspension, inquiry—or worse, lifelong guilt. A Profession Where Perfection Is Not Optional In most professions, mistakes are corrected. In railways, mistakes are recorded, reported, and remembered . Running staff operate under a system where: A signal missed by inches A speed exceeded by seconds A brake applied slightly late can turn into an official memo—sometimes even when no accident occurs. The irony? The system demands machine-level perfection from human beings —humans who are fatigued, sleep-depriv...

Who Are Running Staff—and Why Does Indian Railways Call Them That?

They are the people on duty while the train is running, responsible for safe, continuous, and punctual train operations. In Indian Railways, the term Running Staff mainly includes: > Loco Pilots (Drivers of trains) > Train Managers / Guards (in charge of train supervision and safety) They are different from station staff or office staff because their workplace moves with the train. Why Are They Called “Running Staff”? They are called Running Staff because: 🔹 Their duty is calculated based on train movement (kilometers & hours) 🔹 They work only when the train is running 🔹 Their job starts at sign-on and ends at sign-off, often far f...
