Musical Chairs

 We use reverse osmosis equipment at both Toddington & Cheltenham which roughly turns tap water into distilled water.  This is far better for the locomotive boilers, as less residue gets left behind when the water boils, extending the life of the boiler, meaning less frequent washouts are possible, and no need to perform a blow down every day.  One of the fireman's many duties regarding prepping the loco for a day's service is to take a water sample, which will then be analysed to determine how well the reverse osmosis plant has been doing its job.  Small plastic containers are provide by the water analysis team for the purpose, and all the fireman has to do is to obtain a sample, usually from the lower water gauge test cock, or perhaps the water gauge drain.  I made the mistake of placing the sample container on the warming tray before filling it, and got on with all the other things that I needed to do first... such as lighting the fire.   You can see where this is going already can't you.

 My apologies to the water team!

I had been monitoring our online crew rostering facility with some interest in the lead up to Friday, as nobody had signed up to clean the loco.  I was having visions of having to not only do all the pre-flight checks & the light up, but also having to clean Foremarke Hall as well.  Ade, the driver for the day had also shared my concerns and press ganged encouraged Gwendolyne to come along as well.

 Tom had also noticed that there was no cleaner signed up.  As he was coming along later in the day to put a warming fire into 4270, he took it upon himself to simply turn up considerably earlier than would otherwise have been necessary and help clean Foremarke Hall as well.

 This was of course excellent news as far as I was concerned.

 Somewhere in the far flung corners of the GWSR's social media empire, there is a photo from the lineside drainage gang of Foremarke Hall with an intrepid blogger taking a photo of them, taking a photo of me, taking a photo...

 Leaving home at stupid o'clock on footplate days,means that I only get to hear the shipping forecast on the radio as I drive in.  There is precious little shipping in the general vicinity of Toddington, so the Met Office has taken this as an excuse not to provide a specific forecast for the area.  Clearly they haven't taken the fact that we have a Merchant Navy class locomotive in our operational fleet into account.  The nearest part of the shipping forecast to Toddington is probably the Bristol Channel, for which the forecast was "gale force 8, becoming cyclonic".  I'm no expert in these matters, but quite frankly that didn't sound too good.  Predicatably enough, the weather closed in and several heavy downpours of rain ensued.  Also predictably enough, the rain only occured when we were running tender first.  Foremarke Hall's tender provides a measure of protection, but you are still pretty exposed and will get very wet in short order.  The usual trick for the driver and fireman is to find a cleaner to shelter behind, this causes some problems as there is usually only one cleaner available.  On this occasion, we had both Gwendolyne & Tom, so no problem.
Gwendolyne, rather unimpressed that she is now a weather shield
 No sooner had we got to Toddington and changed direction, than the sun came out.  Perfect comedy timing!
You wouldn't have guessed that it was hammering down five minutes earlier
 For later trips, when the rain came back again, we put up the storm sheet.  It does a fair job of protecting the crew from the rain, but it does make it difficult to see where you're going when running tender first.  The tried and trusted technique of jamming a broom under it to provide a small aperture through which to see was employed to good effect.
It makes sweeping around the footplate a bit of a challenge though.
 Cleaners have noticed that they can earn Brownie points by fetching tea and cake along during the layover at Toddington.

One item of note, was that one of the nifty lights in the yard by the pits, was looking rather the worse for the wear.  Forensic analysis of the traces of yellow paint on the light were found to match the telehandler.  The name of the guilty party has been witheld, but only because he bought me breakfast.
Go home light... you're drunk!
As you may recollect from last week, I mentioned that a game of musical chairs was about to be played with a large crane and the various 2-8-0 locomotives associated with the Dinmore Manor group.  By the time that the music stopped on Monday; 3850 had been turned round to face towards Cheltenham (a move which will facilitate the cylinder block extraction), 3850's old boiler was temporarily placed on 2874's frames, 2874's boiler was rotated through 90 degrees, and 3845's boiler was lifted and brought to Toddington.

 Eagle eyed readers will note that 3845's smoke box was cut through as part of this process.  The smoke box was already unfit for further service, with both the chimney and smoke box ring having been crudely gas-axed out long before 3845 came into DMLL's ownership.  3845 is still in the DMLL restoration queue and the intention is to return it to running order in the fullness of time, however it is at the back of the queue behind 3850 & 2874.

 Moving on to Wednesday, a start was made on the concreting of the last section of the David Page shed floor.  3850's frames were safely tucked away at the back of the shed on road 6, then the first panel of track in the unconcreted section was lifted out, by Terry, Roy, Chris, Tom & Peter.  Getting the old, largely buried concrete sleepers out by hand was deemed to be too much like hard work, so they cheated and got the telehandler to lift them out.

 By now, 3850, facing Cheltenham was isolated on the previously concreted section of road 6.
3850... trapped!
The Wednesday gang also kindly removed the vac cylinders from both 3850 and 2874.  It took a lot of effort, but they both freed up in the end.  3850's dismantled OK, and revealed its innards to be in surprisingly good condition.  2874's proved to be too much of a challenge and has been left for another day.

At some point since emerging from Barry Island scrap yard, somebody had taken the trouble to needle gun and prime 3845's boiler with some form of rust inhibiting paint. That time and effort was well rewarded, as although the paint is rather faded now, it has kept the boiler in remarkably good condition. In most places, needle gunning is not required first, we can go straight in with wire brushes to get back to good clean metal, then apply a fresh coat of rust inhibiting primer, which is exactly what a small team of people got up to on Saturday.

 Saturday also saw more of the track on road 6 lifted prior to the commencement of concreting.

Popping out the sleepers
 There is now a bit of a stack of sleepers in the yard, best keep quiet about them, or P Way will be carting them off to Broadway.

Steam locomotive boilers have a number of safety features built in, one of which is fusible plugs.  The fusible plug is a hollow "bolt", with a lead core, which is screwed into the crown sheet of the boiler and protrudes into the water space.  Should the water level in the boiler fall too low, and the plug protrude above the water space into the steam space, then the higher temperature of the steam will cause the lead plug will melt, thereby emitting steam into the firebox.  This will be noticed by the crew who will then be alerted to the fact that the water levels are dangerously low and that immediate remedial action needs to be taken to prevent the collapse of the crown sheet.

Rod was in the machine shop on Saturday, busy re-leading a number of GWR style fusible plugs for use on our locos.  The plugs have an inner thread into which the lead is melted, of 1/2" W.  Once the plug has been used once, it can be rebored to 9/16W and re-leaded.  After the two uses, it is scrap and a new one has to be made.  This process takes place during every boiler washout.

In fact, here are plenty that Rod made earlier, (scrap ones in the background.)
With Foremarke Hall and 4270 out running the service trains, 35006 was enjoying a relaxing day off... or at least the loco itself was, the owning group were getting on with regular maintenance.  One booked issue has been that the tender brakes drag occasionally.

 Hopefully that won't be an issue next time she runs.  The usual lubrication tasks were being attended to in the cab as well.

I am advised by Steve that a selection of photos are available from 35006's recent visit to the Mid Hant's Railway, hopefully I'll be able to share these with you in the near future.

And finally, one of Saturday's footplate crew managed to leave his hat behind at the end of the day.  Helpfully, one of the many reprobates still present marked the inside of the hat with its owner's name for ease of identification.

The moral of this tale, is that you should never leave anything lying around in the mess coach.

  4. Great blog again-welcome back! The item on water testing reminded me of a colleague whose early job on the railway included sending off water samples to I think, one of the major railway workshops on a weekly basis. Getting fed up with the same standard response, he decided to liven things up by sending off a sample of his own- so to speak! The reply was immediate-'This horse is fatally ill and must be put down immediately'.
