  • A Splendid Monster Nick Baines
    This article was published in the Gauge 0 Guild Gazette Vol. 18 No. 1. The photographs used to illustrate the article have been omitted because they can be found elsewhere on this site. A Splendid Monster Nick Baines That is how the contemporary writer and engineer D. Kinnear Clark described the largest Crampton engine ever to run on a British railway. Liverpool was built for the LNWR in 1848, supposedly to demonstrate that Gooch’s big engines on the Great Western could be matched in size and power by a standard gauge engine. It had the classic Crampton features: a single driving axle behind the firebox, double frames, and valves driven from outside eccentrics. Locating the driving axle at the rear meant that the size of the boiler was not limited by the spacing between the wheels. The boiler was, by the standards of the time, huge, so much so, that the builders evidently decided that an extra pair of carrying wheels was necessary under the boiler, giving it a very unusual 6-2-0 wheel arrangement. Unfortunately, putting the driving axle at the rear meant that it carried only a fraction of the engine weight, which must have limited the traction. Whether because of this, or its reputation for spreading the lightly-laid track of the time, its service life was only ten years, and most of that time seems to have been spent in storage. In spite of that, it has attracted considerable interest from railway historians. For those interested, there is a recent article on Liverpool in the L&NWR Society Journal, Vol.

  • Part 2, S2.6.2 S2.6.2 Ultrasonic Thickness Testing
    PART 2, S2.6.2 S2.6.2 ULTRASONIC THICKNESS TESTING Ultrasonic thickness (UT) testing shall be performed to determine boiler plate thickness. UT testing shall be performed by personnel acceptable to the Jurisdiction and the Inspector. The following requirements shall be met, to the extent possible. Performance and results shall be acceptable to the Inspector and, if required, the Jurisdiction. a) Equipment, operator, and calibration standards used shall be documented. b) To calculate MAWP, ultrasonic thickness testing results in areas of generalized thinning (3 in. [76 mm] in diameter or greater) or where grooved thinning is noted (2 in. [50 mm] in length or greater) are to be used in determining minimum thickness in accordance with S2.10. The MAWP calculation in S2.10 shall be completed based on the thickness data gathered. c)b) On initial UT of stayed sections, the plate thickness readings should be taken on a grid not exceeding the maximum staybolt pitch. Additional readings may be taken close to each staybolt to determine if localized thinning has occurred. Particular attention should be given to the joint between the staybolt and the plate. d)c) On initial UT of unstayed sections, the plate thickness readings should be taken on a grid not exceeding 12 inch (300mm) centers. Additional readings should be taken if conditions warrant. e)d) UT test results shall be documented so location of test results can be checked at subsequent UT tests to determine if material loss has occurred. f)e) Recurring UT testing shall be performed by randomly checking 10% of original UT checks.
