Archive for the ‘Körschtalbahn’ Category

When I last wrote about the Big Diesel (aka ‘Moby Dick‘) I was dithering about how to make the ends, because as usual I was overthinking everything about the project, imagining a dozen different ways to make the curve on the nose and how they could all go horribly wrong.

Eventually I decided that it would be better to actually finish the model at some point and reverted to plan ‘A’.

The problem was that despite my early sketches of the loco I really wanted the distinctive chromed light clusters on the the Brohltalbahn’s D5 or its standard gauge cousin, the Deutsche Bahn type 218. It identifies the locomotive immediately and hopefully makes it clear that the model is in Germany as opposed to Austria or Switzerland. As this will be a somewhat unusual model I wanted to have as many of these visual cues as possible to set the scene quickly in viewers minds.

More to the point I really like the class 218.

For some reason I’d got stuck on the idea that if I didn’t make the nose curved I couldn’t have the 218 styled light bar because… um… Reasons. so I’d followed the idea down the rabbit hole and was looking at the headlight designs on the similar Bulgarian railways type 77 when I happened to come across a type 218 picture and noticed that it has flat ends. Of course it does. I’ve travelled behind class 218’s for hundreds of kilometres and every one of them had an absolute lack of curve on the ends. I’d just… missed it somehow.

I still haven’t give up on the idea of having headlights on the the Henschel diesel for the Körschtalbahn. While working on the cab I realised the various essential electrical bits I’d need for this wouldn’t fit in the ends of the locomotive. Instead I’d have to put them in the relatively generous space in the body, with wires running to the LED’s in the ends.

In a rare flash of forward planning, I decided to make sure there was a route for these wire to run from the ends of the locomotive to the middle so I could put the LED’s in place, finish the locomotive, and then connect the other complex but essential components when I had the money and inclination to add them.

The only problem is that the chassis unit I’m using is rather large, and based around a block of very solid metal, so the wires have to be threaded along a gap between the motor and sides. Then the wires needed to come up in the middle of the locomotive so they could eventually be added to the other bits of electrical gubbins, and the gap was deep down below the substantial bits of plastic that would be used to glue the sides to the chassis.

Above is my solution. When the wires are pushed from the ends down the gap, they should turn along the curved plastic and poke up through a gap, right next to the space where the rest of the circuitry will be kept.

That’s the theory anyway; we shall see if it works in a few weeks…

Remarkably, the project to shorten the Big Diesel seems to have worked out with minimal problems requiring the use of swearing. One of the window frames in the cab windows vanished mysteriously, and the sides are a little bendy, but overall they’re as square as anything else I’ve made and they’re the right shape to fit the chassis, so I’m calling that a positive result.

First lessons learned with the amazing shrinking loco (which will reappear at some point, rest assured) is that a locomotive with sloping sides needs tough bracing to keep it from warping and similar mischief, so I wasn’t sure the original chassis I’d built was going to be up to the job of holding the recently butchered sides straight, so the next job was making a fresh frame. This time I followed the Brick Privvy school of model making and built up the base and sides from laminated plastic card until they were several millimetres thick. In a rare flash of forward planning I even remembered to make the ends angled ready to hold the ends in place.

It may be too much to hope that I actually got the angle right, but allow me some smugness for actually managing to think slightly ahead anyway.

Something I’ve noticed over this year: projects go through phases, and a lot of them make for pretty boring photographs.

Take this picture of the outer and inner sides of the big diesel I’m working on for the Körschtalbahn. Try as I might there is no exciting way to take pictures of a sheet of plastic with holes in it. Trying to take a picture on a filthy wet day doesn’t help either but needs must.

Why did I decide that lots of holes in the side of a model locomotive would be a good idea anyway? It’s not like I enjoy trying to cut straight lines in plasticard.

This is the bit of the project where I just have to keep reminding myself that eventually, there will be a fun but, where all the bits come together, and I can add on details and decide what colour to paint the model, and I’ll generally enjoy myself. This is especially important because when I took those pictures I realised that a couple of those windows are too big: not enough that anyone else will see it probably, but just enough to irritate me.

As I am very keen to break with my tradition of making at least two starts on every model, I’ve tried to repair the damage by welding extra bits of plastic inside the frames, leaving it to set very solidly, and filing and sanding away on the next model making session. We shall see if this works…

There’s a point at the beginning of any project when I really wonder why I bother. It’s the point where I’m trying to do all the boring engineering type stuff to make things fit. If I get this wrong nothing will fit together and the locomotive, wagon, or whatever wobbles about or falls off the track in an embarrassing manner, so I have to just grit my teeth, remind myself that this means there will be fun detailing and weathering to be done later.

It’s a bit like eating your vegetables in the hope there will be a nice dessert.

Anyway. After a certain amount of measuring and false starts, this is the result, a box that fits an old chassis from my stockpile. The gap I the casing is for wires to come through in case I get all enthusiastic about electricity and wire up the LED lights.

It might happen, you never know.

Of course, having done this I realised I’d gone end made life difficult for myself, again because now I can’t just glue everything together: I need to make the outer body clip onto this, just in case I decide one day that I want the lights to work.

Once again I’ve followed a brilliant plan without thinking it through and I’m now dealing with the consequences.

Regular readers, assuming they have been following this blog with the care it deserves, will have noticed that most pretty well all of my projects need about half a dozen false starts as I make something, decide it could be done better/isn’t working, scrap it and start again. In a probably futile effort to avoid doing this yet again, I made a prototype for the cab ends on the not quite a Henschel diesel.

The Liquorice allsort appearance is because I made the corners out of black and white pieces of plasticard, the idea being that it helped me to see how deep and/or straight I was filing.

This worked but it  didn’t look so good, so in a fit of enthusiasm I primed it to see what it looked like.

Remarkably it wasn’t so bad. There were a few rough bits but nothing that I couldn’t deal with next time around. As it was just a prototype I took the lazy option and tried out a colour scheme.

The badge in the middle is was a random idea to try and break up the blank end. I doubt I’ll need this on the production model, because the locomotive is supposed to be a relief passenger locomotive so it will need to have the same connectors as the railcar hanging off the front, a lot of this blank space will be covered by Guitar strings pretending to be connector pipes.

Once again I’m making life more difficult for myself. Just as well I have lot of friends who are musicians…

I sometimes wonder if being more focused would mean I could get more done. I mean, here I am in the middle of making a model of a village, and I’m drawing ideas for a big diesel locomotive that won’t fit on it at all.

On the other hand, this way I get lots more experience than if I was just working on one project: problems solved in one area suggest new solutions for another and I learn faster because of the broader range of experience.

That sounds almost plausible, so I’ll quit thinking while I’m ahead.

The next project, then, is for a B-B locomotive based on the DH 1500 class from Henschel (German text, but the pictures enlarge nicely). These were narrow gauge locomotives, in turn based on the standard gauge Br 218 of similar design which are still running on German Railways. The narrow gauge versions were offered from 1963 and sold to railways in Spain, Bulgaria, Thailand and Togo,  so it would be reasonable to expect the KÖB to have a couple, as they would be replacing their steam locomotives at this time.

The real reason of course, is that I think they look cool. I’ve travelled behind a lot of Br218’s and this is a great excuse to have one of my own. Even better, no-one can say it is wrong.

The Bulgarian examples are still running -along with a rather smart Romanian version- on the 760mm Septemvri-Dobrinishte railway:

 

 

The Henschel machines are the more rounded looking ones with a small grille on the front.

The Spanish locomotives were used by the metre gauge FEVE. When they were replaced one was repatriated to Germany and now runs on the Brohltalbahn, having been rebuilt to look like a Br218 itself. This video shows it hauling a container train.

The most likely version is probably the Bulgarian one, because straight sides are far easier to make.
