35005 Canadian Pacific

That did make me chuckle!

You were correct is was a pressure reducing valve.

Thanks to everyone who has read the post.

 

Proportionately, I'm sure that's right. Maybe something to do with a chain drive inside a tin can.

 

Incase people wondered about I did some digging into that part which I couldnt ID. I am told it is a steam pressure reducing/regulating valve which reduces the boiler pressure down to about 80 psi. Its job is to feed the steam driven electric generator that supplies power to the various lights around the locomotive and tender.

 

Hi guys, I uploaded entry 6 of my volunteer diary working on Canadian Pacific. Some really interesting progress on the beast and well worth checking out.

If you work or volunteer in the railway heritage world we would love to hear you from you. The variety of volunteers is mind-boggling from cleaners to drivers, wagon crew to carriage carpenters, working on miniature railways to mainline express locomotives, from the UK around the globe to Australia – the world of railway preservation is huge and we would like to like to hear from any of you who would like to share your experiences! Support is at hand if you need it, from discussing content to proof reading and it’s all done for free!

 

Except mine, 'cos it has a belt drive primary these days!

Richard.

 

Heretic!

 

I recently found this brilliant of CanPac in Eastleigh work at the start of the year. The photo was taken by Carl Watson (http://www.carlswatson.com/) on the 2nd January. The locomotive has changed alot since but is an impressive sight.

 

Hi guys due to the popularity of my "Volunteer Diaries" working on 35005 Canadian Pacific I decided to do a mini series writing about the locomotives history. The first part is about her time as a Spam Can/Flat Top and wondered what you think. Let me know if you find any errors etc. Thanks

Random bits of information in my head - Was actually design to drop the pressure from 300psi to 80psi so with the rebuilt boiler pressure of 250psi theoretically its more like 67psi. But to be honest, could be any sort of pressure depending on condition on valve and how much its buggered about with.

 

Where does the 300psi come from? The original Bulleids were 280psi, I think, same as the GW Counties.

Prvs don't work like that, the idea is to control on what comes out, so that as the inlet steam pressure alters, you get a near constant out. See http://www.spiraxsarco.com/resource...acting-pressure-controls-and-applications.asp

The offical Mid Hants progress report has been released today (click here)

My blogs tend to stick with what I have physically done so this gives a far more rounded and update report on her stripping down and inspection.

 

But with many PRV's that is only under true flow conditions. Pressure can rise to upstream pressure if dead-headed unless feedback line fitted.

 

Today LocoYard.com posted part 2 looking at the history of 35005 Canadian Pacific. It features its change from a Spam Can to its rebuilt form.

A big thank you to Nigel Kendall who gave me permission to use his brilliant photos.

Finally completed my mini series looking at Canadian Pacifics history. This final part looks at her history and was very hard to research as there is not much online about it but think its come out quite good.

Thanks for reading

 

That is an impressive achievement! Will do some research into that run and edit it in.

 

Here's a video I took of that run in May 1999:

The quality is not very good but hopefully give a flavour of the performance.
