WTR - Wagon Turn Around with Practical example

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). 

Year	1950-51	2000-01	2005-06	2021-22
WTR	11  days	7.5 days	6.08 days	4.74  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

Strategic Lines - Defence

 

Railways - Strategic Lines

For accounting purposes, Indian Railway lines are classified as:

1. Commercial Lines

2. Strategic Lines

Commercial Lines: Commercial Lines are constructed and operated mainly for normal passenger and freight traffic and serve the economic and civilian needs of the country.

Strategic Lines: Strategic Lines are railway lines regarded as important for national defence and military requirements, particularly in border or other strategically important areas.

The word strategic means relating to the achievement of an overall or long-term military advantage.

4 Zonal Railways having Strategic Lines: 

1. Northern Railway (NR) 

2. Northeast Frontier Railway (NFR) 

3. North Western Railway (NWR) 

4. Western Railway (WR)

Memory Tip: North, Northeast, Northwest and West

A railway line is treated as strategic based on national-defence requirements identified in consultation with the Ministry of Defence and approved by the competent authority of the Government. For major strategic railway projects, approval may involve the Central Government or the Cabinet Committee on Security.

Examination Points

• Strategic Lines are maintained separately from Commercial Lines for accounting purposes.

• Separate expenditure statements and accounts are prepared for Strategic Lines.

• Indian Railways reported a loss of ₹2,812.59 crore from operating Strategic Lines during 2024–25.  (as per IR Year Book 2024-25)

• Strategic Lines may also carry ordinary passenger and freight traffic; their strategic classification is based on defence importance, not exclusive military use.

Engineering Code Chapter 18 - Miscellaneous Works - Works required for Defence Purposes - deals with the Strategic Lines. 

• Defence works: Divided between Railway Estimates & Defence Estimates.

• Railway Estimates bears:

• The entire expenditure of Defence Works carried out on the Strategic line will be borne by the Railways.

• Defence Estimates bears: 

• . The cost of construction of troop sidings, platforms etc., including the signaling arrangements required in the event of the siding or platform taking off from the main line beyond the limits of station yard.

•  The cost of land acquired for troop sidings, platforms, etc., if the railway Administration does not choose to acquire it for its own purpose;

•  The interest and maintenance charges on Railway's share of the cost in respect of Defence works executed by Railways on behalf of Defence services.

रेलवे - वाणिज्यिक और रणनीतिक लाइनें

लेखांकन उद्देश्यों के लिए, भारतीय रेलवे लाइनों को इस प्रकार वर्गीकृत किया गया है:

3. वाणिज्यिक लाइनें

4. रणनीतिक रेखाएँ

वाणिज्यिक लाइनें: वाणिज्यिक लाइनें मुख्य रूप से सामान्य यात्री और माल ढुलाई के लिए बनाई और संचालित की जाती हैं और देश की आर्थिक और नागरिक आवश्यकताओं की पूर्ति करती हैं।

रणनीतिक दिशाएँ: सामरिक लाइनें वे रेलवे लाइनें हैं जिन्हें राष्ट्रीय रक्षा और सैन्य आवश्यकताओं के लिए महत्वपूर्ण माना जाता है, विशेष रूप से सीमावर्ती या अन्य रणनीतिक रूप से महत्वपूर्ण क्षेत्रों में।

शब्दरणनीतिकइसका अर्थ है समग्र या दीर्घकालिक सैन्य लाभ की प्राप्ति से संबंधित।

4रणनीतिक लाइनों वाली क्षेत्रीय रेलवे:

5. उत्तरी रेलवे (एनआर)

6. एनउत्तर-पूर्वी सीमांत रेलवे (एनएफआर)

7. उत्तर पश्चिमी रेलवे (एनडब्ल्यूआर)

8. पश्चिमी रेलवे (डब्ल्यूआर)

याद रखने का तरीका: उत्तर, उत्तरपूर्व, उत्तरपश्चिम और पश्चिम

किसी रेलवे लाइन को राष्ट्रीय रक्षा संबंधी आवश्यकताओं के आधार पर रणनीतिक माना जाता है, जिनकी पहचान रक्षा मंत्रालय के परामर्श से की जाती है और सरकार के सक्षम प्राधिकारी द्वारा अनुमोदित की जाती है।प्रमुख रणनीतिक रेलवे परियोजनाओं के लिए, अनुमोदन में केंद्र सरकार या कैबिनेट कमेटी ऑन सिक्योरिटी की भागीदारी शामिल हो सकती है।

परीक्षा अंक

• लेखांकन उद्देश्यों के लिए रणनीतिक लाइनों को वाणिज्यिक लाइनों से अलग रखा जाता है।

• रणनीतिक मदों के लिए अलग-अलग व्यय विवरण और खाते तैयार किए जाते हैं।

• भारतीय रेलवे ने 2024-25 के दौरान रणनीतिक लाइनों के संचालन से ₹2,812.59 करोड़ का घाटा दर्ज किया। (आईआर वर्ष पुस्तिका 2024-25 के अनुसार)

• रणनीतिक मार्ग सामान्य यात्री और माल ढुलाई यातायात भी संचालित कर सकते हैं; उनका रणनीतिक वर्गीकरण रक्षा महत्व पर आधारित है, न कि विशेष रूप से सैन्य उपयोग पर।

इंजीनियरिंग कोड अध्याय 18- विविध कार्य - रक्षा उद्देश्यों के लिए आवश्यक कार्य - सामरिक रेखाओं से संबंधित कार्य।

• रक्षा कार्य: रेलवे अनुमानों और रक्षा अनुमानों में विभाजित।

• रेलवे अनुमानों में निम्नलिखित शामिल हैं:

• सामरिक मार्ग पर किए जाने वाले रक्षा कार्यों का संपूर्ण व्यय रेलवे द्वारा वहन किया जाएगा।

• रक्षा अनुमानों के अनुसार:

• सैनिकों के लिए बने साइडिंग, प्लेटफॉर्म आदि के निर्माण की लागत, जिसमें स्टेशन यार्ड की सीमा से परे मुख्य लाइन से साइडिंग या प्लेटफॉर्म के अलग होने की स्थिति में आवश्यक सिग्नलिंग व्यवस्था भी शामिल है।

• यदि रेलवे प्रशासन स्वयं के प्रयोजन के लिए भूमि का अधिग्रहण नहीं करता है, तो सैनिकों के लिए साइडिंग, प्लेटफार्मों आदि के लिए अधिग्रहित भूमि की लागत;

• रेलवे के हिस्से की लागत पर ब्याज और रखरखाव शुल्करक्षारक्षा सेवाओं की ओर से रेलवे द्वारा निष्पादित कार्य।
