Chronicling the development of my Cambrian and Narrow Gauge 4mm scale model railway

Courting with technology

You know I like oddities. I was perusing the Internet the other day and was reading up on Lentz valve gear. (As an aside- Did you know the chap who invented it was Lenz but the valve gear was called Lentz to help the poor ignorant English speakers pronounce it correctly)

In doing so I came across the GWR’s flirt with it – 2935 Saint class Caynham Court.  

It can’t have been terrible because it remained in service until 1948. 

(Note the incorrect caption in the photo above- Caprotti is a rotary cam valve gear but not all rotary cam valve gears are Caprotti)

More grist to the mill that the P2 boys are on the right track to rewrite history – Lentz valve gear was not a failure – it was the decision to remove the infinite variation of cut-off that doomed Cock o’ the North.

Now rapidly approaching my fifth decade, I am a rolling stock engineer and have worked in many different locations including a 7 year spell in Sydney, Australia, where I arrived with a suitcase and left with a wife and a son. I am now based back in my home county of Yorkshire where I juggle full time work, being a Dad to two rascally mini-mes, and trying to fit in railway modelling and visits to the top left hand corner of Wales. In addition to my heavily railway themed life, I am interested in rugby, cricket, reading crime novels, falconry, and medieval re-enactments.
