Braking retardation on suburban trains is

  • Braking retardation on suburban trains is 3 to 5 km phps.
  • In suburban train service, the braking retardation is typically higher than the acceleration value.
  • This is because suburban trains need to stop and start more frequently than mainline trains, but still need to do so in a relatively short amount of time.
  • Therefore, a higher braking retardation value is necessary to ensure that the train can slow down and come to a stop at each station quickly and safely.
  • The typical range of braking retardation values for suburban train service is between 3 to 5 kmph.
  • This means that when the train operator applies the brakes, the train will decelerate at a rate of 3 to 5 kmph per second until it comes to a complete stop.
  • This relatively high rate of deceleration allows the train to stop quickly and efficiently, which reduces the overall travel time for passengers.
