WTR - WAGON TURN ROUND
M Nageswara Rao 9492432160
Definition: The interval of time between two successive loadings of a wagon is called Wagon Turn Round.
Wagon Turn Round performance is denoted in terms of "Days".
If the No. of Wagon Turn Round days is reduced, the performance considered to be more or vice versa.
In simple terms, "calculated from the time a wagon is placed for loading till the time it again becomes available for reloading", is the actual wagon turn-round.
Thus, all detentions to a wagon, from the time it is placed for loading till it is again placed for reloading after passing through the cycle of loading, dispatch, transit, unloading and again made available for reloading, enter into the calculation of turn-round.
Means wagon turn round is 11 days means, the wagon could be loaded around 32 times a year. (360 days/11 days).
This (Reduction of Wagon Turn Round days) has been achieved as a result of
Improved mobility of wagons.
Quick loading & unloading of wagons.
Reduction in detentions.
And improvement in speed of goods trains.
Formulae for WTR - Wagon Turn Round = WB/(L+R)
WB is Wagon Balance (effective average), L is Daily average number of wagons Loaded, R is Daily average number of wagons Received.
Practical example of WTR:
Calculate Wagon Turn Round from the following data:
Daily Average Wagon balance: 15500
Average daily non effective wagons A) Sick - 200 B) Departmental -300
Average daily loading – 800 (L)
Average daily received – 700 ( R )
Answer:
Effective average wagon balance daily = Wagon balance minus Sick & Dept
= 15500 - (200+300)
= 15000
WTR = WB/(L+R)
WTR= 15000/(800+700)
WTR= 10 days
Wagon is the bread earning horse of the Railways, load it adequately. Make it run and don’t stabilize it.
Key Takeaways for MCQ:
Expressed in terms of “Days”
WTR = WB/(L+R)
WTR stands for Wagon Turn Round
WB stands for Wagon Balance
L stands for Average Daily Loading
R stands for Average Daily Receiving
More efficient, if WTR is less or vice versa
