F_α = (277.8*W_e*α)+(W*R_sp)
This formula uses 5 Variables

Variables Used

Acceleration Tractive Effort - (Measured in Newton) - Acceleration Tractive effort to the force exerted by a locomotive or a vehicle's driving wheels on the track, which is necessary to overcome the resistance and accelerate the vehicle forward.
Accelerating Weight of Train - (Measured in Kilogram) - Accelerating Weight of Train is the effective weight of train that has angular acceleration due to the rotational inertia including the dead weight of the train.
Acceleration of Train - (Measured in Meter per Square Second) - Acceleration of Train is the rate of change in velocity to the change in time.
Weight of Train - (Measured in Kilogram) - Weight of Train is total weight of the train in tonns.
Specific Resistance Train - Specific Resistance Train is defined in terms of force required to encounter resistance arising due to vehicle, track, grade, curve, acceleration, wind at different time and place etc.

STEP 1: Convert Input(s) to Base Unit

Accelerating Weight of Train: 33000 Ton (Assay) (US) --> 962.500110009752 Kilogram (Check conversion here)
Acceleration of Train: 14.4 Kilometer per Hour Second --> 4.0000000000032 Meter per Square Second (Check conversion here)
Weight of Train: 30000 Ton (Assay) (US) --> 875.000100008866 Kilogram (Check conversion here)
Specific Resistance Train: 9.2 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

F_α = (277.8*W_e*α)+(W*R_sp) --> (277.8*962.500110009752*4.0000000000032)+(875.000100008866*9.2)

Evaluating ... ...

F_α = 1077580.12316377

STEP 3: Convert Result to Output's Unit

1077580.12316377 Newton --> No Conversion Required

FINAL ANSWER

1077580.12316377 ≈ 1.1E+6 Newton <-- Acceleration Tractive Effort
