PREFATORY NOTE
This compendium of instructions is issued for guidance of officials dealing with the subject matter. It contains all administrative orders issued from Railway Board from time to time, which have relevance on date. All those circulars and letters issued on the subject prior to and on 30/06/98 and not contained in this compendium are deemed to be cancelled or superseded. The compilation in the compendium is to remain up-dated and for documentation purposes. However, rules and provisions of the original circular / letter issued from the Board constitute the final authority on the original circular / letter issued from the Board constitute the final authority on the subject and not this compendium. Therefore, this compendium should not be referred to as an authority except for identifying the valid circulars / letters issued by Board and to exclude all other letters / circulars issued prior to 30/6/98 and not contained in the compendium.
While all out efforts have been made to make the compendium exhaustive yet, corrections to this compendium may be required and shall be issued serially numbered. In the next edition, mention shall be made of the number of incorporated correction slips. Remaining correction slips continue to remain in vogue till the next edition and so on.
The compilation of this compendium brought out need of regularly updating relevant codes and manuals and also the need to exercise restraint in issuing policy directives which are already contained in a code or manual or require correction / deletion / addendum to a code or manual or a previous policy directive. The compendium throws light on all such areas and, apart from the fact that a lot of corrections have already been carried out, a follow up action plan has been drawn and is being pursued to achieve this goal of field staff referring to the relevant Codes and Manuals and their correction slips only and minimal reference to circulars / policy letters etc.
The compendium covers following subjects.
Zonal Railway may supplement the instructions, however taking care that these do not contravene the provisions of the codes and general rules.
It is hoped that, as already advised, CEs shall take similar action regarding the compendiums of their circulars etc. issued by Engineering Branch and keep them updated.

D. Rail Fracture & Weld Failure
8. Sub: - Action Plan to Achieve Zero failure on selected important routes.
Various measures are suggested to achieve zero failure of rails and welds, like, carrying out frequent USFD, U.S. testing of thermit weld, re-welding of same, de-stressing of LWR, gap survey, special patrolling, out of turn renewals, imposition of suitable speed restrictions, improvement in quality of track, proper blasting, attention to joints, elimination of formation problems, proper drainage, renewal of scabbed and corroded rails etc.
