The text states, "...the underframe should be painted with two coats of red oxide zinc chromate primer followed by the four coat system of anti-corrosive bituminous paint."

When discussing body bolster repairs, the text says, "Check the area surrounding center pivot pin mounting holes for cracks."

The text specifies, "Electrode: IRS Class B2 of approved brands."

The text says, "Magnesium oxychloride or plywood/compreg with PVC overlay flooring in the lavatories and bays adjacent to lavatories of all coaches over six years old should be broken and trough floor thoroughly examined."

The text refers to "sequential POH repairs" and "coaches after POH repairs," indicating it means Periodic Overhaul.

The tool list for the Lifting Shop includes "Goggles for inspection staff."

The text mentions, "Where the corrosion noticed is of a very minor nature and has just started... the paint and the rust should be thoroughly cleaned to reach the bare metal and the surface treated with two coats of red oxide zinc chromate primer."

The text instructs, "Before the corroded portion is cut off, the auxiliary head stock and the two sole bar ends should be firmly supported to rail lines."

The text lists that the under-frame supports "air-conditioning system... air or vacuum brake system... under slung water tank, etc."

The text says, "End wall consists of four vertical pillars of box section..."

The text mentions, "Below lavatory the tubular constructions are provided... to avoid corrosion... In coaches with stainless steel trough floor, no tubular structure is used."

The text states, "Distorted and bent parts should be heated and straightened."

The text specifies, "Corrosion resistant steel sheet for trough floor, pillars, side-wall and roof to IRS M.41-97."

The tool list shows "EOT cranes" are present in both the Lifting Shop and the Corrosion Repair Shop.

The text mentions, "Thoroughly clean and remove dust, rust accumulated at pillars through turn under holes with coil brush and compressed air."

Para 214b for Schedule 'B' says, "In addition to para 214a do the following. Examine trough floor, turn under and other under frames from underneath for corrosion."

According to para 214a, Schedule 'A' is to "Check visually the following for any damages/defects/deficiencies."

The text states, "Welders deputed to carry out welding work on coaches and coach components should be only those tested and certified as adequately skilled."

The caution explains that without proper earthing, "the return current passes through axle roller bearings causing pitting of rollers and bearing failure in service."

The text has a clear caution: "No electric welding on the coach should be carried out without proper earthing from near the portion being welded..."

The text states, "Cracks shall be detected by doing chalk testing or magnaflux dye penetrant test."

The text says, "All coaches after POH repairs should be tested under water spray for roof leakage... a fixture designed to simulate monsoon conditions should be provided in the workshop."

The text states, "The securing bolts should be replaced whenever a ventilator is removed."

The text instructs, "Before cutting off the corroded portion of sole bar, both the adjacent ends should be supported to the rail lines."

The text specifies, "Only 8 mm thick corrosion resistant steel sheets should be used for head stock repairs."

The text explicitly states, "For repairs to side wall and end wall, no lifting is required."

The text mentions "Red oxide zinc chromate primer - IS 2074-62" as the paint for the primer coat.

The text specifies, "It is essential to use corrosion resistant steel sheets for corrosion repairs of coaches," and mentions the specific standard "IRS M.41-97."

The text states, "Replace head stock if the wear is more than 4mm i.e. when the thickness is below 4mm."

Section 202d lists several vulnerable locations, including sole bar at door opening, body pillar at lavatory, head stock, and turn under at lavatory. The center of the roof panel is not mentioned in that specific list.

The text specifies, "A component will require repair/replacement, if it has lost more than 20% of it's thickness."

The text mentions that components "not visible from both sides should be examined by tapping with a spiked hammer. Proper illumination will be required to carryout the check."

According to the text, "Inspection and repair of body members are done after the coach body is lifted off the bogies and placed on trestles."

The text explains that the head stock consists of "outer and inner head stocks connected by two rigid center buffer stiffeners, which transmits all the buffing forces to the under frame structure."

The text clearly states, "Below lavatory the tubular constructions are provided in place of trough floor to avoid corrosion due to seepage of water."

The text specifies that the framework is "sheathed all over by 2mm thick corten steel (IRS-M-41) on the side walls."

The text describes the framework as "a series of hoops, consisting of floor crossbeams, body side pillars and roof carlines located transversely at regular intervals."

The text mentions, "Anti-telescopic structure has been provided in the end-walls to avoid telescoping of the adjacent coaches and to absorb the major part of collision energy..."

According to the text, "Corrugated sheets are utilised for the trough floor to form part of the tubular construction as well as to absorb a large portion of the buffing forces."

The text states, "The concept of the lightweight integral design originated in the recognition of the properties of hollow girders... The reduction in tare weight... could be achieved by utilising 'stressed skin' concept."
