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.

Having now officially reached middle age, 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, assisting the GWR 1014 County of Glamorgan project, 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.
