The Shed allocations shown above are not shown on the boiler record cards, but have been given so that a better understanding of the mileage figure would ensue.

One of the things I find strange is that there is no mention of the replacement of Superheater Tubes in the above or on any other Record Cards that I have perused. As all (well nearly all) of the Boilers were re-tubed at least once in their lifetime, the superheater tubes would have had to be removed to do this work. Although a drawing was produced in 1940 for a modified Superheater header which incorporated the Ball and Socket ends to the Superheater Tubes, not many boilers seem to have received this modification. This allows for the easy removal (relatively speaking) of the Superheater Tubes without damage. Whereas the original header had the Superheater Tubes expanded into the header, which does not allow for easy removal, and damage was bound to occur, also the Superheater Tubes themselves were subject to wear and tear and must have needed replacing at some stage.

BOILER No. 29324

Onto Eng No. 60015 1/5/53 to 2/9/54 (WL 1yr 4mths), OOU 2mths, onto Eng No. 60017 3/11/54 to 17/11/55 (WL 1yr 0mths), OOU 3mths, onto Eng No. 60015 10/2/56 to 12/6/57 (WL 1yr 4mths), OOU 6mths, onto Eng No. 60007 13/12/57 to 10/3/59 (WL 1yr 3mths), OOU 3mths, onto Eng No. 60028 10/6/59 to 1/3/61 (WL 1yr 9mths), OOU 2mths, onto Class A3 Eng No. 60075 12/5/61 to 13/1/64 (WL 2yrs 8mths). Boiler withdrawn with Engine at this date. Total WL 9yrs 4mths, Total OOU 1yr 4mths, Total Life Span 10yrs 8mths. 6 Uses.

It is reasonable to assume that a revue of the Diagram 107 Boiler in 1956 showed that there were 67 boiler extant at that time. Of those 67 up to 20 of the initial boilers were at or very near their 20th year of service, and could be said to be nearing the end of their working life. So in 1957 5 more boilers were put into service. The boilers they were possibly meant to replace, in some cases carried on for another 6 or 7 years, and ironically these 5 new boilers, because of policy changes, only had a short life span. As far as the Works were concerned, this was a bonus, as they were able to cascade the surplus boilers onto Class A3 Engines.

REQUEST FOR INFORMATION

Four Diag 107 Boiler are known to have been used as Stationary Boilers. Can anyone confirm the dates when the following boilers were in use as Stationary Boilers and the locations at which they were so employed.

Boiler No. 8949, renumbered 29287, became Stationary Boiler No. 999

Boiler No. 8950, renumbered 29293, became Stationary Boiler No. 1000

Boiler No. 8955, never renumbered, became Stationary Boiler No. 961

Boiler No. 9019, renumbered (Later 29309), became Stationary Boiler No. 960 in the middle of its working life, and as such is fairly well documented.

Two other Boilers are believed to have been employed as carriage heating boilers in the Kings Cross District, at the time the Diesels were taking over the work on the Sleeping Car Trains. Any details whatsoever on these two boilers would be appreciated. Thank you.
