In the matter of the Rules and instructions for the inspection and testing of locomotive boilers and their appurtenances:

Hugh Wardrope
Assistant Chief Commissioner

F. M. MacPherson
Commissioner

H. B. Chase
Commissioner

It is ordered that the rules and instructions for inspection and testing of locomotive boilers and their appurtenances prescribed by General Order No. 473, dated May 22, 1929, as amended by General Order No. 531, dated December 18, 1934, General Order No. 725, dated June 1, 1949, and General Order No. 760, dated July 31, 1951, be, and they are hereby amended by

  1. striking out Rule 11 as prescribed by General Order No. 473 and substituting therefor the following:

    Inspection of Exterior of Boiler

    (11) Lagging to be Removed—The jacket and lagging shall be removed after sixty calendar months' service provided such service is performed within six consecutive years and a thorough inspection made of the entire exterior of the boiler while under hydrostatic pressure. The jacket and lagging shall also be removed whenever, on account of indications of leaks, the Board's Inspector or the railway company's Inspector considers it desirable or necessary.

    The period for inspection of the exterior of boilers built or rebuilt subsequent to January 1, 1923, may be extended in certain cases, upon formal application to the Board's Director of Operation, if investigation shows that such extension of time is warranted.

  2. by striking out rule 18(a) as prescribed by General Order No. 725 and substituting therefor the following:

    Method of testing flexible staybolts with caps

    (18)(a) All staybolts equipped with caps over the outer ends shall have the caps removed upon completion of 60 calendar months actual service, provided such service is performed within 6 consecutive years, at which time all bolts and sleeves must be examined and effectively tested for breakage or fracture. Portions of calendar months out of service will not be counted. Time out of service must be properly accounted for by out of service reports, and notations of months claimed out of service made on the back of each subsequent inspection report and cabcard. Each time a hydrostatic test is applied, the hammer test required by Rules 16 and 17 must be made while the boiler is under hydrostatic pressure not less than the allowed working pressure.

    Locomotives of United States railway companies running in International service between United States and Canada are permitted to operate in Canada provided the requirements of the Interstate Commerce Commission regarding staybolts are fully complied with.

    Where boilers have been built or re-built subsequent to January 1, 1923, the period for removal of caps and examination of bolts and sleeves may be extended in certain cases upon formal application to the Board's Director of Operation, if investigation shows that such extension of time is warranted.
