Posts Tagged ‘DH 1500 Locomotive’


I’ve finally managed to get the big diesel project moving. again. Why I chose a complex locomotive with curved ends and sloping sides is open to question but it seemed a good idea at the time.

I was feeling pretty pleased with progress but when I held up the locomotive next to the chassis earlier this week, I realised I’d designed the model about 10mm longer than it needed to be.

I’d claim I was trying to make the locomotive sleek and purposeful, but I probably just got carried away and added a bit here and a bit there, and ended up with a loco that looks sleek and purposeful but will go around corners like a tram.

After thinking about this*, I worked out four places I could make the locomotive 10mm shorter:

1: Remove 10mm between the drivers door and the two lower grilles on the bodyside (Compare with the top image, there is a difference).

2: Remove one drivers door on each side. The locomotives supplied to the Bulgarian railways only have one door per side, so I can claim it’s prototypical, and it would mean less cutting to go wrong, although it would be good if I can make sure each cab has at least one door.

3: I could just make the window in the bodyside 10mm shorter, but that makes it rather a strange shape:

4: On the other hand, removing 5mm from the window and another 5mm between grilles and door, a combination of 1 and 3, would have the same effect with less of a visual change, and the fuel cap would still be central on the side of the loco.

The disadvantage of this is that I’d have to make four cuts into the bodyside, which knowing me is four cuts to get wrong and make a wonky locomotive…

Thoughts and ideas are welcome. I’ve even made a poll, tech savvy modeller that I am, although I don’t promise I’ll follow the result.

One of these days, I really might manage to make a locomotive on the first attempt instead of getting fed up and starting again.

Not this time around though. After cutting out all the holes I put the finished sides away with a nice smug feeling which promptly vanished when I took them out again a few days later to find that several of the pieces were not even pretending to be the shape I planned.

On top of this, I wasn’t happy with the ends of version 1: they looked, well, ugly. Worse, the locomotive had the feel of a home made miniature railway locomotive. Nothing against miniature locomotives you understand, but I wanted a heavy freight diesel on a go-getting modern transport organisation that happened to use a narrow gauge railway, and this wasn’t really giving that impression.

So I started redesigning. Here’s version 2:

There is a marked similarity to Brohltalbahn D5, formerly working in Spain, now hauling trains up murderous gradients south of Bonn, but it includes a few details from different versions, on the basis that that Henschel made the locomotives slightly differently for all their customers so no-one can say I’ve got it wrong. Having tried to ignore the slight tilt to the sides on most of the Henschel locomotives I’ve given in and added one on this, which makes a massive improvement to the profile view.

the drawback is I actually have to build the thing like this now.

I’m still not entirely sure about the light clusters. The locomotives would have been refurbished recently so a more modern light cluster may be more appropriate, and make the loco look a bit less like a D5 clone. Will have to think about this…

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…
