Splet26. apr. 2024 · The tractive effort required can be defined or given in two situations, one is in level track and the other in inclined track. When the train is moving on a level track, then the acceleration due to gravity will be zero. Therefore on leveled track, the tractive effort required is given by, F t = F a + F r [F g = 0] dynamic vs static characterization

SpletWe will be begin by discussing Tractive Effort or Tractive Force, which is the amount of force at the wheels available for moving a train. 1. Energy Utilization. To move any object, a force must be applied to overcome the resistance or inertia of the resting object. The object remains at rest until sufficient force is applied.

SpletTractive System The energy meter has 3 TS connections. The first two connections are bus bars on either side of the meter. This is a shunt for measuring current. These must be wired in series with the TS on the negative side such that all power supplying the tractive system passes through the energy meter.
