GMT - Gross Million Tonne - Statistics in IR

 


GMT - Gross Million Tonne (Statistics in IR)

What is GMT ? 

  • Gross = Total Load i.e., Carrying Capacity (Tare Load + Payload) 

  • Million = 10 Lakhs

  • Tonne = 1000 Kgs 

  • I.e., 100 Crores Kgs  or 1 Million Tonne 

  • GMT is a primary performance metric   - serves 3 groups of Railway Statistics in IR Statistics Manual i.e., 1. Economic Statistics 2. Transportation Statistics & 3. Administrative Statistics. 

  • GMT data of every train on every line  - captured on FOIS / ICMS / CoA

  •  FOIS stands for Freight Operations Information System 

  • ICMS stands for Integrated Coaching Management System

  • CoA stands for Control Office Application

  • Traffic Density Data (GMT)  - an integral part of Indian Railways IT Systems architecture. 

Why GMT is important: GMT data is a crucial decision criterion for 

  • Planned Track Renewals 

  • Preventive maintenance (like periodicity of USFD - Ultrasonic Flaw Detection) 

  • Riding quality (Track degradation model) 

  • Effective allocation of rails, track materials & resources, among works/projects under Plan Heads 11 - New Lines, 15 - Doubling & 31 - Track Renewals.

Existing mechanism (up to 2022-23) - calculation of GMT 


  • Computed by Zonal Railways 

  • Basis is GTKM & Lead (Kms) 

  • Manually input in TMS - Track Management System 

  •  Limitation is for sections with more than 2 lines (i.e., 3rd/4th line), the line wise GMT data is not available.  


New mechanism - from 2023-24 onwards   - calculation of GMT 


  • Zonal Railways would provide GMT data by May of the following year.  Example: For 2023-24 the data should be available by May 2024 and so on. 

  • All GMT data in TMS  - sync (API based) with the systems architecture

  • API stands for Architecture Programming Interface

  • No physical copies. No manual input in TMS - Track Management System

  • No signed copies in parallel 

  • GMT data from FOIS/ICMS/CoA would flow daily into TAMS - Traffic Accounts Management System   ( SMRTI - Statistical Module on Rail Transport Information) 

  • From TAMS to TMS 

  • From 2024-25 onwards - GMT data - refined format i..e, Block section wise Line wise  (earlier line was not available) 

  • Zonal Railways Statistical Units (under PFA)  - issue Monthly & Annual GMT Data

  • SPOC for Statistical Information Module   - GM/TAMS @ CRIS 

  • SPOC for input data of FOIS/ICMS/CoA - GM/OR @ CRIS

  • SPOC stands for Single Point of Contact 

  • It is calculated for Railway Tracks involving multiple factors and is a complex process. 

  • It is determined through detailed engineering analysis and simulation. 


GMT Calculated for Railway Tracks involving multiple factors.  These are: 


  1.  Axle Load: Higher axle loads leads to greater wear and tear. 

  2. Train Speed: Higher speeds can cause track degradation. 

  3. Train Frequency: The number of trains passing over a track within specified time (Line Capacity) can affect stress & wear on the track. 

  4. Track structure & Material: Ballasted or non-ballasted track and the material used play a significant role in determining load capacity & maintenance requirements. 

  5. Climate & weather: Extreme temperature or heavy rainfall conditions impact the Track’s durability. 

  6. Track maintenance practices: Frequency of track maintenance influences the overall track performance. 


Note: The above instructions are in supersession of any previous instructions on the subject (GMT) and in the event of conflict with any other instructions / part of any other instructions, the above instructions would prevail. 


Key points -  GMT 


  1. GMT is a primary performance metric   - serves 3 groups of Railway Statistics in IR Statistics Manual i.e., 1. Economic Statistics 2. Transportation Statistics & 3. Administrative Statistics. 

  2. Statistical units in Zonal Railways - under control of PFA 

  3. GMT  - Revised policy   w.e.f 01.4.2024 onwards  (or FY 2023-24 onwards) 

  4. GMT means Traffic Density Data 

  5. GMT data from FOIS/ICMS/CoA would flow daily into TAMS - Traffic Accounts Management System   ( SMRTI - Statistical Module on Rail Transport Information)

Traffic Costing and Statistics

 

Traffic Costing


  • The Railways manufacture and sell the commodity i.e., Transport

  • Railway transport influences the pricing of commodities. Rail transport costs enter into the cost of commodities and affect the general price level. 

  • Hence suitable measures have to be adopted to reduce the cost of haulage, increase speed, comfort, safety and punctuality which not only helps the customers/traders, but also develops the nation’s economy in the ultimate analysis


Objectives of Traffic costing: 


  1. Provide basic data for rate fixing

  2. Carrying out the profitable analysis of existing and potential traffic 

  3. Create cost consciousness  and help in cost control

  4. Provide data for project appraisals and evaluation of further capital investment 


Distinguishing features of Traffic costing


  1. Pan India: 

Railways operated throughout India consists of thousands of Railway stations all over India (not limited to the particular area like in Road Transport)

  1. Non homogeneity of end products: 

The Transport (commodity) is not homogeneous. Common costs are used for passenger and goods traffic


  1. Perishable commodity: 

Like any other transport, Railways transport is a perishable commodity i.e., it cannot be stored. If a Wagon is not utilised for loading on a particular day, its transport capacity is lost forever. 

  1.  Huge infrastructure:

Creation of vast costly assets for a long span and Rail transport depends on the efficient usage of the same.  


  • Revenue expenditure is classified into 14 Revenue Abstracts i.e., A to O (except I) 

  • 14 Revenue Abstracts:

 

  • Functional:  7 Abstracts -  Maintenance - B,C,D & E and Operating Expenses - F,G & H

  • Overheads: 7 Abstracts - A,J,K,L & M

  • Others: 2 Abstracts - N & O

Notes:

  • There is No Abstract bearing alphabet ‘I’  

  • Erstwhile Demand No. 12  - Two Abstracts - K & N 

  • Erstwhile Demand No. 13  - Two Abstracts - L & O


  • The above Abstracts are called as Sub Major Heads 

  • The Sub Major Heads are further divided into more than 1200 Minor Heads 

  • This 1200 number will multiply many times, when Primary units (Object of expenditure) are suffixed to each detailed head (last two digits of the Classification of Revenue expenditure)


Type

Consists of 

Consignor

Packing, Charges for loading goods into trucks, Transport from consignor’s godown to the Railway Station, Unloading and loading of the Consignment into the Wagon

Consignee

Delivery of consignment at the Destination station i.e., Cost of unloading from Wagon and loading in Truck and cost of transport from the destination station to consignee’s godown

Imputed

Also called Inventory Costs 


Interest charges on the capital value of Goods locked up during the period of Transport. 


Formulae: Inventory Cost per Tonne = V x R x T / 365


V -  Value of Tonne of Goods  


R - Annual Rate of Interest 


T - No of days in transit from Consignor’s Godown to the Consignee

 

Hence delay in transit puts the Consignee at a loss because inventory costs will go up. 


If Railway transit takes longer time, traders would prefer Road Transport which takes much less time, even though Railway Freight may be lower.   

Trader

Consignor Cost + Consignee Cost + Inventory Cost + Freight 


Trader’s Cost is useful for comparing Railway freight with the Road Transport freight.  


Trader’s cost - Goes into the price of Commodity in the Market

Operator

Acquisition, Maintenance, Operation, Improvement, Replacement of transport facilities, compensation for damages, interest on borrowed money, Dividend on Capital, etc.  

Economic

Cost of transport to the Nation in terms of national resources of labour and material 


Its calculation is required for resource allocation on different means of transport.  


Also, take into account the cost of movement of goods by other means of transport also 


Excludes: Element of all taxes and duties of Central and State Governments


Key Points for MCQ 


  1. Imputed costs also called Inventory Cost 

 

  1. Formulae of Imputed / Inventory Cost per Tonne  = V x R x T / 365  

 

  1. V - Value of Tonne of Goods 

 

  1. R - Annual Interest Rate 

 

  1. T - No of days in transit from Consignor’s Godown to Consignee 

 

  1. Trader’s cost = Consignor Cost + Consignee Cost + Inventory/Imputed Cost + Freight  

 

  1. The trader’s cost goes into the price of the commodity in the Market 

 

  1. Economic Cost excludes Taxes and Duties paid by the Central Govt. and State Govts. 


Regression Analysis

  • General meaning is Reversion 

  • Helps in working out ratios for allocation of joint expenses between services of Passenger & Goods

 

  • Defined as Statistical Tool 

 

  • Meaning: “The act of going back or returning” 


  • A method of correlating two closely related variables


  • With this tool, we are in a position to estimate the unknown values (dependent cost) of one variable from the known values (independent costs) of another variable.  This is called Regression analysis 


  • Known variables – Basis – Independent 


  • Unknown variables – Derived – Dependent 


  • Widely used for prediction and forecasting 


  • Estimates the value of the dependent variable changes when any one of the independent is changed while the other independent variables are held fixed. 


  •  Example: Relationship between :


  1. Advertisement and Sales 

 

  1. Demand and Price 


  1. Good Monsoon & Crop 


  • The earliest form of regression method   - Method of Least Squares –developed by Mr Legendre in 1805. 


  • Y = f (x, B) where Y = Dependent variable, f = Function,  x – Independent variable and B = scalar/vector



 

Statistics in Railways - An Introduction 


Sources:  


  1. Manual of Statistical Instruction Volume 1

  2. Statistics Manual 1 - Introduction 


Origin of the word Statistics:  German “Statistik” means Description of a State or a Country


Definition: The discipline that concerns the collection, organization, analysis, interpretation and presentation of Data. 


Characteristics:  

  1. Numerically expressed 

  2. Aggregate of facts 

  3. Systematically collecting the Data 

  4. Should be comparable to each other. 

  5. Data is collected for a planned purpose. 

  

Statistics in Indian Railways: 


  • Statistics Organization Incharge - Executive Director Statistics & Economics, who works under the control of Member Finance in the Railway Board.  

  • Statistical Officer is incharge at Zonal Railways, who works under the control of PFA  



History of Indian Railways: 

  • Official Use - Printed triennially (every 3 years). 

  • Sale to the Public - Published Sexennially (every 6 years)

  • From 1969 onwards - Published decennially (every 10 years) 


Factors - Railway Statistics: The Railway Statistics are based on the following factors: 

  1. Quantity - Expressed in the number of tonnes and passengers transported and earnings derived. 

  2. Distance - Expressed in Kilometers 

  3. Duration - In Hours and Days 

  4. Service - In Trains, Vehicles, Wagons & Engines 


  • The above Primary Units are linked together to express in Composite items called Fundamental Units.  That is Fundamental Unit = Linking of Primary Units. Examples are: 

  1. Tonne Kilometres ( Fundamental Unit) - Tonnes & Kilometres ( Primary Units) 

  2. Passenger Kilometres (Fundamental Unit)  - Passengers & Kilometres (Primary Units  


  • Derivating Units: Relationship that exists between two sets of Primary Units or Fundamental Units are called as Derivative Units. Examples are: 

Derivative Unit = Primary/Fundamental Unit + Primary/Fundamental Unit

Derivative Units

Primary / Fundamental Units

Primary/Fundamental Units

Earnings Per Passenger 

Passenger Earnings (Primary)
