Re: Locomotive balance weights

The balancing of locomotives is a complex mathematical subject - if you want to understand the technical detail, one of the best publications is 'The Balancing of Engines' by Prof WE Dalby FRS, first published by Edward Arnold in London in 1901, with subsequent updates in 1906 and 1909. The book is ...

Re: Another Dunalastair model.

Hello Mike, I've no experience of making Joy or any radial valve gears, my building being focused at scales where there is always lots of room for Stephenson's or Walschaerts' motion - usually at 7.25" gauge. I've attached an image of the loco when the boiler was removed so that I could free the sei...

Re: Another Dunalastair model.

Most interesting to read of the Dunalastair IV model. Just over 12 months ago I acquired a 2.5" gauge Dunalastair IV Superheater Model, No 139, complete with bogie tender. The loco was built around 50/60 years ago, has a superheated boiler (2 flues with single return loops) and an operational steam ...

Many thanks for your responses, which accurately pin the location. I believe the photographer may have been HL Salmon.

Re: Where is this, please?

Just to muddy the water on piloting a little more, I attach a Henry Salmon image for which I have the glass plate. It depicts No 132 piloting No 864 on what appears to be a mixed freight working including cattle wagons, and judging by the 'whiteness' of these wagons, a fair amount of lime wash has b...

Re: Where is this, please?

Jim,

I believe this is Beattock Summit, the train approaching from the south, and the date may be April 1922. In my 956 book I used a Henry Salmon image of No 938 passing the same spot on that date. See Plate 16, page 30. The siding on the left side is a 'run off' from the Up loop.

Re: Caledonian relations with other railways?

The difficulties in relationships between the CR and NBR at Stirling and the related partisanships persisted certainly until the mid 1950s. Readers may know that the CR (LMS) main line north of the town bisected the NBR routes and facilities: to the east of the CR main line lay the NBR engine shed a...

CR 0-4-0STs - Working outwith Sctland.

A question has arisen as to which of the CR 0-4-0STs worked in England, where they worked, why they were selected for the relative locations and for how long they worked at specific locations. As for as I can gather from the CRA photo-archive No 56027 was at Crewe works and perhaps also at Derby, No...

CR 0-6-0ST No141/516/1516

Bertram Baxter (British Locomotive Catalogue, Vol 4, page 66) states that CR 0-6-0ST No 141 (subsequently No 516 in 1877) was used intermittently in the construction of the 'Oban line', which would probably refer to the 1873-1880 period, though use in the Ballachuilish extension might be inferred.

I believe it is Kingmoor, since the structure, with its rounded shoulders appears in several photographs of 956 Class engines, all the images being taken at Kingmoor In several images it appears to be freshly painted white.
