Traction Mechanics is the study of train motion.
The mechanics involves conversion of overhead electrical power/diesel/steam power in rail horse power to haul a train encountering acceleration, train, grade, curve resistance and similarly braking.
Traction Mechanics involves concept of
for detailing the motion of a train.
The units followed in day to day talk of Raiways are different as compared to conventional MKS system. Conversion table is given below for better understanding
|Energy/Work||kWh||kWh||W-sec or N-m or Joules|
where D-distance;V-final speed; U-initial speed; a-acceleration
where W in N-m or Joules or Watt-sec)
where TE is in Kgf, V in Kmph and HP=75*Kgf*m/sec
where η is efficiency of Loco
