Wagon Numbering System in IndiaWagon Numbering System in India A new wagon numbering system was adopted in Indian Railways in 2003. Wagons are allocated 11 digits, making it easy for identification and computerization of a wagon's information. The first two digits indicate Type of Wagon, the third and fourth digits indicate Owning Railway, the fifth and sixth digits indicate Year of Manufacture, the seventh through tenth digits indicate Individual Wagon Number, and the last digit is a Check digit. First Two Digits These two digits indicate Type of Wagon. Open Wagon Code allotted is from 10 to 29 Code allotted Type of Wagon 10 BOXN 11 BOXNHA 12 BOXNHS 13 BOXNCR 14 BOXNLW 15 BOXNB 16 BOXNF 17 BOXNG 18 BOY 19 BOST 20 BOXNAL 21 BOSTHS 22 BOXNHL Covered Wagon Code allotted is from 30 to 39 Code allotted Type of Wagon 30 BCNA 31 BCNAHS 32 BCCNR Tank Wagon Code allotted is from 40 to 54 Code allotted Type of Wagon 40 BTPN 41 BTPNHS 42 BTPGLN 43 BTALN 44 BTCS 45 BTPH 46 BTAP 47 BTFLN Flat Wagon Code allotted is from 55 to 69 Code allotted Type of Wagon 55 BRNA 56 BRNAHS 57 BFNS 58 BOMN 59 BRSTH 60 BFAT 61 BLCA 62 BLCB 63 BLLA 64 BLLB 65 BRS 66 BFU 67 BRHNEHS 68 BCL 69 BCLA Hopper Wagon Code allotted is from 70 to 79 Code allotted Type of Wagon 70 BOBYN 71 BOBYNHS 72 BOBRN 73 BOBRNHS 74 BOBRAL 75 BOBSN Well Wagon Code allotted is from 80 to 84 Code allotted Type of Wagon 80 BWTB 81 MBWT 82 DBKM 83 MBWZ Brake Van For Brake Van code allotted is from 85 to 89 Code allotted Type of Wagon 85 BVZC 86 BVZI Third & Fourth Digits These two digits indicate Owning Railway Code allotted Owning Railway 01 Central Railway Zone 02 Eastern Railway Zone 03 Northern Railway Zone 04 North Eastern Railway Zone 05 Northeast Frontier Railway Zone 06 Southern Railway Zone 07 South Eastern Railway Zone 08 Western Railway Zone 09 South Central Railway Zone 10 East Central Railway Zone 11 North Western Railway Zone 12 East Coast Railway Zone 13 North Central Railway Zone 14 South East Central Railway Zone 15 South Western Railway Zone 16 West Central Railway Zone 24 Wagons owned by Defence 25 Wagons owned by CONCOR 26 Wagons owned by other private parties Fifth & Sixth Digits These two digits indicate the last two digits of the Year of Manufacture For example 08 for 2008 15 for 2015 Seventh to Tenth Digits These digits indicate Individual Wagon Number. This is a running serial number from 0001 to 9999. Numbers 0001 to 0999 are departmental stock. Numbers 1000 to 9999 are for other traffics stock. Last Digit This is a Check digit. The Check Digit for each wagon is calculated using a six-step algorithm as indicated below. Let the wagon number be C1 C2 C3 C4 C5 C6 C7 C8 C9 C10 C11. (C1 is the first digit, C2 is the second digit, and so on) Step 1 : Starting from the left, add all the Characters in the even position. S1 = C2 + C4 + C6 + C8 + C10 Step 2 : Multiply the sum by 3 to get 3×S1 Step 3 : Starting from the left.. add all the Characters in the odd position. S2 = C1 + C3 + C5 + C7 + C9 Step 4 : Add the sum of step 2 to the sum of step 3 to get S4= 3×S1+S2 Step 5 : Round this total up to the next multiple of 10. Step 6 : The check digit is the number required to the added to round up to the next multiple of 10 An example for the calculation, Let the wagon number is 31101695215 Step 1 : S1 = C2 + C4 + C6 + C8 + C10 = 1+0+6+5+1 = 13 Step 2 : 3 × S1 = 39 Step 3 : S2 = C1+ C3 + C5 + C7 + C9 = 3+1+1+9+2 = 16 Step 4 : S4= 3 × S1 + S2 = 39 + 16 = 55 Step 5 : Next 10th multiple of 55 = 60 Step 6 : Check digit = 60 - 55 = 5 Hence the eleventh digit is assigned as 5 for this particular wagon. Abbreviations Used for Wagon Type Code Gauge code M :- (prefix) MG N :- (prefix) NG Wagon type code B :- (prefix) Bogie wagon (sometimes omitted) BV :- Brake van V :- Brake/parcel van (see above for brake van codes) O :- Open wagon (gondola) C :- Covered wagon (boxcar) F :- Flat car FK :- Flat car for container transport FU :- Well wagon LA :- Low flat car with standard buffer height LB :- Low flat car with low buffer height LAB :- Low flat car, one end with low buffers, the other with high buffers R :- Rail-carrying wagon T :- Tanker (additional letters indicate material carried) U :- Well wagon W :- Well wagon K :- Open wagon: ballast / material / refuse transport (older wagons) C :- Centre discharge S :- Side discharge R :- Rapid (forced) discharge, bottom discharge X :- Both centre and side discharge X :- (also) High sided Y :- Low (medium) side walls L :- Low sided H :- Heavy load The ‘B’ indication is sometimes omitted as all new wagons are bogie stock. Following the type code in the classification code a letter may denote the type of coupler, nowadays optional, as all new freight cars are fitted with centre buffer couplers (CBC). An 'N' suffix is for 'pneumatic', or air-braked wagons. Most newer stock that is air-braked also has CBC couplers, so the 'C' is usually dropped. E.g., BOXN for air-braked BOX wagons, not BOXCN. Almost all the older stock is vacuum-braked. Coupler, brake, and other suffixes C :- Centre buffer coupler (CBC) R :- Screw coupling only T :- Transition coupler (CBC with additional side buffers and screw coupling) N :- Air-braked M :- (suffix) Military * Read also our other many web pages on India Rail Transport: | |||||
