NS 2400 - 3D printed model

Most of my train collection encompasses German trains, mostly because you can buy them everywhere. Nothing wrong with that of course but being Dutch, I would like to be able to have some Dutch trains.

Of course there is Philotrain, very exclusive, nicely detailed, but not widely available and pretty expensive. Most Philotrain models are made for display, not really for extensive driving either.

Well, in my opinion there are lots of loco’s to choose from when you look at the Dutch railways. I wanted to try something not too difficult, which has led me to the NS2400.
It’s a pretty simple loco when it comes to curves and shapes, the design originates in French: Alstom.

I wanted to try to make it by using 80% 3D printing technique.
First of all, to start I made a 2D drawing to get to know the loco.

After that, I started with the basic shapes of the upper body to get the right feeling with the Loco. Everything had to be designed to meet the guidelines for Grey Resin Material. This material has a bouncing box from 250x250x235cm, so the complete loco would never fit. De body of the loco is designed as parts which click together.

First off all started drawing separate parts:

For the bogies and the main frame, I used Polyamide (nylon),this is very strong and durable. The bogies are designed as 3 separate parts. The middle frame holds the engines (20/20B), the wheels, and the pick-ups. The bogies are screwed on separately.
The main frame is drawn as one piece, which will also be printed in Polyamide.

I made some colour previews to see what it could look like

Compared to the Grey Resin, the Polyamide is not as smooth. But that shouldn’t be a problem if you weather the model later on.

It will still take some time to finish the model, but I’m very content with the looks and feel it’s already got.

Hello Olli and Matthias,

The loco is/will be powered by 3x 20/20b Faulhaber engines, I thinks that should be more then enough.

The nylon is, when you print it, not as solid as when you compare it to a "normal" piece of nylon. So in the beginning when you spraypaint it, it will suck upp the paint into the material.
I used standard Motip car paint for the first baselayer on the bogies and the main frame.

Next step will be drawing the wire grill on top and on both sides of the loco. I'm thinking of using the etching skills of Jurgen Moog for that.

Kind regards,

Okke

Hello Stefan,

To be honest, I have no idea how many hours are in there. I started drawing in March, and finished in I think in July? I don't really keep a log.

I have nothing to do with the E103 project, I have enough projects on my own and don't want to work with others because then i have to finish stuff.... I mostly work on all kinds of projects at the same time, and when I can't find the energy to finish a project, I put it aside to restart it at a later time.
I do watch the project of the E103 with great interest, but that's it I'm afraid.

Now to answer your last question, it will be finished when it will be finished, depends on my mood, time, etc

Kind regards,

Okke

Hello Thomas,

Well, I think time will tell.
But I designed the model to get it's stability when screwed together.
De resin itself, it's pretty stable. The nylon has the tendency to deform if not supported, but screwed to the resin body, it's very straight.

Kind regards,

Okke

Today the loco did make it's first test drive.
NS 2413 test drive

For those of you who want to see it in real life, next week during the "Spoor nul dagen" in Zutphen, it will be on the tracks.

Kind regards,

Okke

Find the differences:

The two on the left are Philotrain models.

Last week I finally received the last cast parts from Shapeways. Each time it turned out that there were too few support points in the drawing, so that it was rejected.

Now the loco has finally been completely sprayed with Motip spray paint.

To keep the locomotive running smoothly, it is now equipped with a new ESU decoder with an external power buffer.

The next step is to provide the glass and the wipers have yet to be made.

Greetings Okke

Hello Ralf

The fine air grills are not from Shapeways, but from a neighboring second hand store. That grill had served in some kind of wind light, and I bought it for the mere 25 cents.

Hello Valéry,

I fitted the bogies with Faulhaber 20/20B. On the motor I pressed a brass gear wheel module 0.5. On the wheel a nylon gear wheel modul 0.5 to reduce noise.

The pickups are made of nickel silver and are pressed into the bogie frame. The wheel sets themselves turn in a brass bush.

I do not offer the parts for the locomotive for sale, I do not want to become a dealer or seller. I protect myself and my hobby in this way.

Kind regards,

Okke
