Testing Times (1)

Tuesday 23rd February 2016 was an important day - the day an inspector called. In this case Peter Hawkins the boiler inspector.

It had been a busy few weeks leading up to this but essential to be ready for action on the S&D 50th anniversary of the line closure on March 6th 1966.

There were various tests: A general inspection of paperwork covering materials used, certificates of conformity and calibration; a hydraulic test to 1.5x working pressure (412.5 psi) to check boiler fittings were attached properly; a maxed-out steam accumulation test to abuse the boiler and check the safety valves could cope; a test of the ability to keep the boiler filled with water under maximum output conditions.

Giving the clouds a shock!
If you are wondering what Sentinel 7109 sounds like when being steam tested, try this video clip: (Higher def. on YouTube)
We also tried a less formal haulage test on the 1 in 53 gradient as in the following video clip (Higher def. on YouTube):
There are interesting times ahead!

(And it passed the tests too!).

  2. My son and I visited MSN yesterday and saw "Joyce" running splendidly by the side of the "trip train". Thank you for breathing new life into such a wonderful little engine.
