2.0 Wagon Holding on IR(As on 01.04.2020) 2.1 Indian Railway wagons are manufactured in Railway Workshops (ASR/NR, GOC/SR, JMP/ER, SPJ/ECR& UBL/SWR), PSUs (Braithwaite & Company Limited, SAIL-RITES Bengal Wagon Industry Private Limited) and Private Wagon Builders (Texmaco Rail, Modern Industries, HEI, Besco(WD), Titagarh Wagons, Jupiter Wagons, Cimmco, Besco(FD), Jindal Rail, Amzen, SRBWIPL, Oriental, CEBBCO). 2.2 Final Inspection of Wagons at PSUs and Private Wagon Builders is done by Quality Assurance (Mech.), RDSO, while in Railway Workshops inspection is done by Neutral Control Organisation (NCO). 8

5.0 NEW NUMBERING SYSTEM OF WAGONS Monitoring and liquidating overage arrears of rolling stock is a focus area in the interest of safety of train operations. However, some of the Railways have reported difficulty in ascertaining the age of wagons where the manufacturer’s plate is missing. Also computerization of wagon data is becoming cumbersome with development of various versions in a category e.g. BG bogie open wagons BOXN, BOXNHS, BOXNAHA, BOXNCR, BOXNHL, BOXNR and BOXNLW are being clubbed together by the computer cell and shown as BOXN in the holding. To overcome the above-mentioned problems and to facilitate computerization of the wagon data base, a new wagon numbering system was introduced by Railway Board as per Letter No. 2000/M(N)/60/2/wagon census. Dated 4th July, 2003 In the new scheme, the wagon number shall consist of 11 digits as follows: It can also be remembered as TOYS i.e T: Type of Wagon (Two digits), O: Owning Railway (Two digits), Y: Year of Manufacture (Two digits), S: Serial number of wagon (Four digits) The codification for various types of wagons, owning railways, year of manufacture and individual wagon no. are as follows: 27
BVCM 87 28
5.1 YEAR OF MANUFACTURE CODE (C5, C6): This will consist of last two digits of the year of manufacture. For example wagon manufacture in 2016 will have code 16. 5.2 INDIVIDUAL WAGON No. (C7, C8, C9, C10): This will be running serial number from 0001 to 9999. Numbers 0001 to 0999 will be departmental stock and 1000 to 9999 will be other (traffic) stock. This will be running number irrespective of year. For departmental, after 0999, the number will begin from 0001. For others, after 9999, the number will begin from 1000. The series will not change with type of wagon. For example on ECR if 1001 is BOXNHS next wagon which may be BCNHS will be 1002. 5.3 CHECK DIGIT – Method of calculation The CHECK DIGIT for each wagon is calculated using a six-step algorithm based on ten digit wagon number arrived at as indicated below. 29
6.0 Cartridge Tapered Roller Bearing (CTRB) The Cartridge Type Taper Roller Bearing (CTRB) has two inner races (cones) along with rollers and cage, separated by a spacer, a single case-hardened outer race (cup), a grease seal and a seal-wear ring at each end, a backing ring at the rear, axle end cap, 3 cap- screws, and locking plate. The cup also acts as the bearing housing and is fitted in the bogie side frame with a suitable adapter (See General Arrangement of CTRB Drg. No.WD- 92089-S-01 for Narrow Jaw adapter & WD- 13042-S-01 for Wide Jaw adapter. The weight of Class 'E' 6 X 11 CTRB is around 34.3 kg, weight of Narrow Jaw Adapter is around 12.0 kg and wide jaw Adapter is around 23 kg. a) There are basically two types of CTRB i.e Class E (6’’X 11’’) and Class K (6 1/2’’X9”). Class E type CTRB is used in all air brake freight stock and govered by RDSO spec no. AB/RB-39/2002 whereas class K CTRB is used in 25 t Wagons only which is governed by AB/RB-41/2016. b) Recently, Railway Board has directed to use upgraded CTRB class E in all freight stock other than 25 t wagons vide L/No. 2017/M(N)/951/14, dt 18.09.2019 which is governed by RDSO spec no. AB/RB-40/2016 in which polymide cage and low torque grease seal will be used. c) RDSO approved suppliers of Class E CTRB are M/s NEI, Jaipur, M/s Timken, Jamshedpur and M/s SKF, Ahmedabad d) RDSO approved supplier of Class K CTRB is now M/s NEI, Jaipur. However, as RDSO vendor directory (Validity 01.01.2020 to 30.06.2020), till such time vendors are approved for this specification (RDSO STR NO. AB/RB-41-2016), Orders are to be placed on vendors who are approved by AAR. Following 03 (three) sources have AAR approved design and manufacturing facilities for K Class bearing – 1. M/s National Engineering Industries Limited. 2. M/s SKF India Limited. 3. M/s Timken India Limited. Class E CTRB 30

7.0 RFID Tags on Wagons (Radio Frequency IdentificationTags) a) The purpose of providing RFID tags on freight stock is to result in Automatic Wagon Identification using Radio Frequency Identification. b) Fitted at DV & Non DV Side of wagons. Information like Year of Mfg, Owning Rly, Wagon Type, Wagon Serial No., Date of entry of data, Mfg code, Station Code are entered in the tag. c ) . Specification No. 2016/CRIS/NDLS-HQ/CC/PROJECT/RFID/0225/Pt.1 dated 05.10.2018 under which RFID tags (V4.1) are procured. d). Data reading of RFID is illustrated below; 33
8.0 Types of Bogies 34
8.1 BOGIE TYPES- CASNUB BOGIE 35
8.2 CASNUB→ CAST STEEL + SNUBBER SPRING This Bogie is tested in India in 1972 with BOI Wagon.After this it is tested in BOXN Wagon with 90 kmph speed.CTRB used in CASNUB bogie. 22.9 ton Axle load. Wheel size – 1000 mm Condemning wheel size - 905 mm Wheel Base - 2000 mm Wheel Gauge - 1600 mm Distance between journal centre -2260 mm Distance between side bearers -1474 mm Three types of Centre pivot used in Casnub Bogie:- a. IRS type b. Hemi spherical c. Flat type centre pivot 8.3 Development of CASNUB Bogie CASNUB-22W: Wide jaw category without EM Pad. No locking at centre pivot & bolster pin. Brake beam is pocket type or sliding type. Maximum speed 75 kmp. Side bearer roller type. The disadvantage of this bogie are:- a. Higher wheel wear b. Replacement of brake beam requires removalof wheel set. c. Low stability as vertical load not shared byside bearer. 36
CASNUB 22W(M) Major difference in the side frame as compared to 22W is provision of Negative camber(sag at the middle of the side frame)to maintaining same buffer height while using EM pad. EM pad has been introduced along with adapter to reduce higher wheel wear as experienced with 22W version. Spherical type centre pivot fitted with bolster. Metal bonded side bearer used in this version for improving the stability of Wagon as compared 22W version. Hanger type brake beam used with separate brake head through spring loaded brake shoe adjuster. Main disadvantage of this bogie is dropping of brake beam and grazing of brake components. CASNUB-22W(Retrofitted) The main difference with 22W are: Use of Elastomeric pad with adapter Use of constant contact metal bonded elastomeric pad in side bearer housing. To accommodate elastomeric pad& to maintain buffer height the height of the adapter has been reduced because it is not possible to use higher diameter wheel set to maintain the buffer height. Wheel below dia. of 956 mm is to be used in this version. 37
CASNUB 22 NL Narrow jawcategory. The side bearer, centre pivot, bolster are similar to 22W(M)version. Centre pivot pin is locked by shackle lock as compared to castle nut used in 22W(M)version. The adapter used with this version is of smaller size to suit to narrow jaw opening of the side frame. CASNUB -22NLB This is similar to 22NL version except for bolster. The shape of bolster is ‘fish belly’ at the centre to reduce the weight of bogie. Narrow Jaw Category Brake beam moves in pocket 38
CASNUB -22NLM The only difference is change in material of the side frame and bolster. The equivalent carbon % of side frame and bolster in NL/NLB is 0.85%.This has reduced the weight of bogie. The weight of the NLM version bogie is 5.125 ton where as the weight of NL version is 5.5 ton. CASNUB-22HS The CASNUB-22HS bogie has been developed for high speed operation up to 100 Kmph. The side frame, elastomeric pad, centre pivot, centre pivot lock,adapter are similar to NLB version. The spring loaded constant contact type PU side bearer used in this bogie. Initially Spring loaded side bearer is used, now PU type side bearer is used Springs are not interchangeable. 39
