Random Disconnected Diatribes of a p&p Documentation Engineer
A holiday weekend, and it rained. What a surprise. Still, it meant I actually got round to fulfilling a promise from a few weeks ago about firing up the film scanner and digitalizing some of the better ones of my collection of old railway slides. So, if you are not a railway fanatic maybe should stop reading now and find some other technical blog about computers (or play another game of FreeCell). The rest of this post is just pictures of old trains...
By way of some background to my pre-computing geekiness, my trainspotting episode started in around 1965 when steam was in the last stages of giving way to diesel. Most of my memories of steam engines are seeing them passing through Gloucestershire on their sad and final trip to the scrap yard in Barry, South Wales. However, my real passion in those days was for the gleaming new diesel hydraulic Western and Hymek locos that thundered past our house. Though travelling the world and the UK with parents serving the Royal Air Force meant that I lived (and trainspotted) in a variety of locations. Unfortunately, it was only in the late 70's that I owned a good enough camera to start recording what I saw.
Since then, trains have become a minor peripheral part of my life as marriage and work (and growing up) took over. So I can't actually provide a detailed history or record of any one period. Though occasional day trips to preserved railways and (now derelict) railway infrastructure and installations does provide the occasional fix. Still, here's a selection of the resulting digitalized memories:
British Rail Class 9F 92220 "Evening Star". The last steam loco built by BR (in 1960), and now preserved as part of the National Collection.
GWR 7812 "Erlestoke Manor" built at Swindon works around 1938, seen here in 1980 approaching Highley on the Severn Valley Railway.
LMS "Black Five" 5305 leaving York with a steam special in around 1980. Now refurbished and running on the Great Central Railway.
British Railways 73050 "City of Peterborough" built in Derby in 1954 and seen here in 1987 at the Nene Valley Railway.
Class EM1 76007 and 76008 built in 1953 and seen near Woodhead Tunnel on the Manchester-Sheffield route around 1978, shortly before the line was closed.
Diesel Hydraulic "Western" class D1062 "Western Courier", built at Crewe in 1963 and seen here on the Severn Valley Railway in 1980.
An unidentified "Brush" class 47 leaving Peascliffe Tunnel on the East Coast Main Line in 1979 before electrification of the route.
The "Deltic" Class 55, the most powerful of the mainline passenger diesels and my personal favorite of all diesels. This is 55 003 "Meld" built in 1961 at the Vulcan works in Newton-Le-Willows and named after a famous racehorse. Seen here at Doncaster in 1979.
British Rail adapted some of the 08 class shunters to work as tandem units in Tinsley Yard, Sheffield. This is 13 001 seen in 1979 on the yard hump.
An unusual visitor to Doncaster, having just left the BREL works after refurbishment. Originally built in 1968 at the Vulcan works, this is class 50 007 "Hercules" (later renamed "Sir Edward Elgar"). The locos were often known as "Hoovers" due to the sound of the large engine room fans.
And finally, for U.S. readers and tram fans, New York Third Avenue Transit number 674 seen here on a rainy day in June 1990 at Crich Tramway Museum in Derbyshire (just a few miles from where I live).
I also found a selection of slides taken inside the British Railways Engineering (BREL) works at Doncaster in 1979. After I sort them out, I'll post a few of the more unusual ones...
I was reading a story (a.k.a. urban myth) this week about an eminent quantum physicist who was stopped for speeding in his car. When told by the traffic cop that he was doing 63 miles per hour, he responded by asking if this was an accurate measurement. Being told that it was he explained that, therefore, they could not definitely determine if he was inside the 35 miles per hour zone at the time. Alternatively, if they were sure that he was within the zone, it was physically impossible - due to the fundamental laws of quantum mechanics - for the speed measurement to be accurate.
OK, so the story was phrased a little more colloquially that this. When asked if he knew how fast he was travelling, the eminent physicist replied "No, but I know where I am". Of course, our eminent physicist was simply explaining that, according to the Heisenberg uncertainty principle, it is impossible to simultaneously determine the precise values of certain pairs of physical properties, such as position and momentum, of an object.
It's an interesting theory; and you may want to ponder if, when you measure the transfer rate of your high speed Internet connection or the performance of a new super fast hard disk, the results actually apply to your neighbor's DSL line or your wife's laptop instead. Although in reality this effect only reveals itself where you are dealing with very small or very fast things. Perhaps if I write this blog post using 6 point Arial, and type fast, there's a danger that the text might end up in a different paragraph, or even a different document.
And as for really small and fast things, you don't get much better than the electrons that make up the ones and zeros of your latest and greatest computer programs. So there's definitely a danger that, if you make your new enterprise application run too quickly, you won't be able to tell which server it's running on when you come to do performance testing. Probably a good argument for installing a server farm.
And does this uncertainty extend to other pairs of physical properties? Can I argue that my spelling is so bad because it's impossible to determine the actual alphabetic letter and its position within a word at the same time? Or insist that my BMI must be around 25 because it's impossible to simultaneously measure my weight and height? Perhaps if I was also running very fast at the time it would work.
However, what's really disappointing is that Heisenberg's principle also puts paid to my idea for becoming a millionaire by patenting a device for removing the space junk that I keep reading is increasingly endangering satellites and space craft in Earth orbit. I'd just finished the design for a rocket fitted with a large magnet when I read that most of the junk is travelling at six miles per second - which probably means that I can't determine how big the chunks are. So how would I know what size magnet I'd need?
One of my previous jobs involved travelling to a variety of locations selling things. Amongst those locations was the British Rail Engineering works (BREL, more familiarly known as just "The Plant Works") in Doncaster, South Yorkshire. It was one of those amazing old Victorian factories where you felt like you had stepped back 100 years as soon as you walked into one of the huge old brick buildings. It reeked of history and those wonderful engineering aromas of cutting fluid, oil, engines, and ancient machinery.
But getting inside was, to a geek or trainspotter, like finding the Holy Grail. And I was lucky, one day in April 1979, to be taken - complete with camera - on a private guided tour. So, if you are interested in railways, you may just find the following photos and notes interesting...
At the time, the works was building the Class 56 freight locos. Here you can see the assembly line, the power plant, the assembled loco, and the finished result:
The works also refurbished diesel multiple units. Here are before and after views:
BREL maintained the Deltic fleet. Unfortunately, they were short of one engine so there was always one Deltic sitting forlornly in the yard - in April 1979 in was 55 020 "Nimbus". In the photo here, 55 015 "Tulyar" is undergoing refurbishment.
Another section of the works was, during 1979, refurbishing the "Hoover" class 50 locos, which operated mainly on the Western Region at that time. The photo shows 50 043 "Eagle" ready to go back to work, with Class 31/1 number 31 301 alongside in for running repairs:
Some of the class 50s managed to bring forward their planned refurbishment. This is 50 003 "Temeraire" awaiting some serious attention after a collision:
And, of course, more than a few locos ended their life as spare part donors:
And that's enough railways. Next week look out for (as Monty Python always used to say) something completely different...
Let's face it, those of us who work in the hi-tech world of computing tend to think of ourselves as being - well, not to put too fine a point on it - intellectual; even skilled artisans of our trade. We string lumps of extremely complex hardware together so they can talk to each other, write clever code that executes mind-boggling tasks in the blink of an eye, and build wonderfully intuitive and interactive interfaces for our applications. And all before lunch some days.
Yet once you step outside of our world of information technology to accomplish something far more down to earth, such as a task that is practical in terms of most people's day to day lives, you suddenly realize just how little our skills have in common with the real tradesmen (and women) of this world. How something that seems like it should be really simple, compared to software design patterns and administering enterprise systems, is really much harder to do well than firing up Visual Studio and tossing it some code, or plugging network cables into a server and setting up the DNS.
OK, so I'm no great programmer. My IT skills tend to come into play further down the line, after some of the really clever people around here write the code. But, as I discovered, I'm not much of a carpenter or plasterer either. When you watch real skilled artisans at work, it seems like what they do is simple - until you try it yourself. I reckon these people are really artists rather than just artisans. They apply the techniques of their trade with an artistic flourish that belies the skills, years of practice, and experience required.
Like most DIYers, I realize that it's reasonably easy to achieve a semi-professional outcome with some jobs. I can paint a door so there are no drips, blobs, or patches. I can do plumbing and house wiring with a confidence that it will work afterwards. I've even done gas fitting when we fitted out a kitchen some years ago, though I did get that tested by a professional afterwards. And I can usually mend simple stuff that breaks. I can even cut glass and do glazing work (after spending several years working with greenhouses for a garden supplier).
So when we took the old gas fire out a few weeks ago (see Firing Up the Imagination) and it left a two foot square hole right through the wall to the outside, I reckoned I could do most of the work to put it right. OK, so I have a pal who is a builder and I let him brick up the hole (I know for a fact that the art of bricklaying is not one of my proficiencies). But surely plastering up the remaining bit and putting on some new skirting board can't be that hard?
Oh yes it is. Even after three attempts and half a roll of sandpaper to try and get rid of the bumps and rough edges, it still looks like someone threw a rice pudding at the wall. Luckily the new fire covers most of it. And simply fitting a new chunk of skirting board into the gap between the existing pieces took hours of work. Mind you, it didn't help that the new piece has a slightly different profile to the existing stuff. But even careful shaping, delicate lining up, and half a tub of filler (plus, of course, the rest of the roll of sandpaper) couldn't make it blend in.
The trouble is; what else do you do? Have you ever tried to find a plasterer who will come out and plaster a hole two feet square? Or a carpenter who will pop in and fit three feet of skirting board? Usually all you get is laughter at the other end of the phone. I suppose it's like asking a developer to come round just to rename a couple of variables in your code, or calling out an admin guy in the middle of the night just to reboot your laptop. Or even getting your tame documentation engineer to change the formatting of two words in the middle of a huge help file. Err... just a minute - I have to do that all the time. So maybe I'm an artist after all...
