Brake Power Certificate requires recording of Feed Pipe (FP) and Brake Pipe (BP) pressures in both engine and brake van, along with attachment time, ready time, and departure pressure.

Warranty Card format includes specific fields: Due date of warranty inspection, date of inspection (by depot), defects attributable to manufacturers, remarks with cost advised by Railway Board, and report number.

The total number of direct activity days for POH of Non-AC LHB coaches is 16 days, which is 5 days less than AC coaches due to absence of AC equipment maintenance.

Corrosion attention (Activity 5a) in Non-AC LHB coach POH is allocated 3 days direct, allowing thorough inspection and repair of corroded areas.

Activity code D (Lifting and Lowering) is allocated 4 days direct, which includes dismantling bogie components, lifting, bogie washing, repairing, and lowering of coach.

The total days of direct activities for POH of AC LHB coaches is 21 days, with multiple parallel activities running simultaneously to optimize workshop time.

A copy of the write-off memo should be submitted to the Budget section of the divisional Headquarters office for exhibition in Appropriation Accounts.

Upon receipt of the additional deficiency list, the OC/RPF of the base station will arrange to fix responsibility for the additional deficiencies and take suitable action.

On arrival at workshop, if additional deficiencies are noticed, a list of such additional deficiencies is made out in four copies jointly by Mechanical, Electrical, and RPF staff.

Upper-class coaches must be padlocked/locked with a carriage key and also sealed after the joint check at the starting station to prevent pilferage during transit.

One copy of the deficiency list should be pasted inside the compartment on one of the end walls for reference during transit and at destination.

Before any carriage is allowed to proceed to workshops, a joint check is carried out and deficiency list prepared in five legible copies with proper reference, number, and date.

LED-based destination Boards should be provided as per extant instructions by Railway Board and RDSO's specifications RDSO/2009/CG-01 Rev-01 of Feb'10 or latest.

The facilities required for en-route coach watering should be as per CAMTECH's design detailed in report CAMTECH/2009/M/C/terminal Attention/1.0 of March 2009.

After dressing the final weld contour by little grinding, finally check by Dye Penetrant Test (DPT) to ensure no cracks remain. If any crack noticed, repeat the procedure.

If AC welding machine is used, it must have Open Circuit Voltage (OCV) minimum 70 Volt to ensure proper arc stability and penetration for quality welds.

Root run is done with 3.15 mm diameter electrode with higher current for proper penetration, and subsequent runs are done with 4 mm diameter electrode for efficient filling.

Before welding, drill a hole of 7-10 mm diameter at about 15-20 mm away from the extremities of crack to prevent further crack propagation during welding and service.

The repair procedure for cracks on sole bar near yaw damper bracket should be carried out as per ED/STD (Carriage)/RDSO letter No. MC/LHB/Coach, dated 10.10.2007.

P.U. surfacer/touch up on shell is to be carried out as per instruction issued by RCF/Kapurthala vide document No. PLW 905 dated 09.06.2004 and M&C/PCN-100/2006.

Lower Flange (Part No: 7&16, 8mm-IRS M41-97) is specifically identified among vulnerable locations requiring corrosion inspection due to its position and loading.

Web (Part No: 22, 6mm-IRS M41-97) is specifically listed among vulnerable locations requiring careful corrosion inspection during underframe examination.

For workshops, CBC height under tare condition must be between maximum 1105 mm and minimum 1090 mm, a tighter tolerance than production units which have minimum 1095 mm.

Coupler height shall be adjusted by adding or removing shims as per procedure described in chapter 5 of the manual.

Before lifting, Centre pivot security plate must be removed. If lifted from one end, the Centre pivots security plate is likely to suffer damages.

After lifting, coach body should be kept on steel trestles of the design shown in Figure 2.4, which are specifically designed for LHB coach support.

SS-I is precisely specified as 18 months + 30 days OR 6 Lakhs km earned, whichever is earlier, ensuring timely overhaul based on either time or usage.

D2 (Monthly) Schedule has periodicity of 30 days ± 3 days, while D3 (Six Monthly) has 180 days ± 15 days, providing defined windows for maintenance scheduling.

Warranty on quality of POH during POH of rolling stock at the workshop is governed by Railway Board letter no. 2022/M(W)I/814/4 dated 13.06.2022.

If signs of corrosion are noticed above lifting pads, the side wall sheet should be cut to a height of 500 mm and to a length of half meter (500 mm) on either side of lifting pads.

If incidence of corrosion is noticed in the bottom half of the sole bar at lavatory area, the trough floor should be cut to a width of 300 mm and requisite length for examination of inside top half.

Guideline for Corrosion Repair in LHB Design Coaches is detailed in CMI No RDSO/2019/CG/CMI-01 version-2.0 issued on May 2021, which is enclosed as Appendix E in the manual.

Longitudinal member top flanges (ltemnos: 14&15 as per drg no: LP11105) and Flange Plates (ltemnos: 11&12 as per drg no: LP11105) are identified as more prone to corrosion in LWLRRM luggage compartment.

Sole bar sections are precisely specified: AC Chair car uses 238x65x6, AC Power car uses 238x65x8 (thicker due to higher loads), and both types also use 238x65x4 at certain locations.

Top flange (Part No: 5&6, 4mm-IRS M41-97) under lavatory modules is specifically identified as a vulnerable location requiring special attention during corrosion inspection.

Sound insulation thickness is precisely specified by location: floor residual regions receive 2-3 mm, while floor near bogie areas inside receive 6-8 mm for enhanced damping where vibration is higher.

Decoupling elements installed in the flooring system prevent direct transmission of structure-borne noise, complemented by elastomeric rubber-metal components in the bogie assembly to isolate vibrations from the coach body.

Resonaflex Alu insulation is available in thickness ranging from 20 mm to 100 mm with 5 mm steps, allowing precise selection based on insulation requirements for different coach areas.

Side wall, End wall and Roof structure use X2CrNi12 Ferritic steel conforming to RDSO Specification No. C-K 201, Amendment-1 with Corrigendum No.1 of October 2015, which specifies exact chemical composition parameters.

IRS M-41 Corten Steel has precise composition including Nickel 0.20-0.47%, Copper 0.30-0.60%, and Chromium 0.35-0.60%, which together provide enhanced atmospheric corrosion resistance through formation of protective patina.
