    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.

    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.

    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.

    A worthwhile compilation. It might be worth noting that one of its finest achievements in blue was on the Mayflower in May 1999 when it ran from Bristol to Plymouth and return.The whole day was quite a tour de force for the engine. Outbound she ran non stop to a signal stop outside Exeter in 73 minutes with a remarkable minimum of 62 over Whiteball. West of Exeter she also demolished Dainton and Rattery banks with mins of 35 and 33 respectively, but the best was to come on the return. After a spirited dash to Exeter in 64 minutes including a check before arrival, she then ran non stop back to Bristol in 74 and a half minutes for the 76 miles and that included a slow entry from Parson Street due to a TSR and signals. Whiteball was taken at 64 with mile after mile covered at line speed over the Somerset Levels.

    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.
