Hi all,

P1060775a.jpg

I acquired one of these little items many years ago and they are quite neat. I do seem to have a bit of a thing for these if this old topic is anything to go by.....

https://www.marklin-users.net/forum/posts/t20382-Homemade-VW-Railbus--Drasine--G1-Maxi

Unfortunately, the main issue with mine is that it's a 2-rail DC version #452, rather than the AC 3-rail version #451. Apparently there was a short-lived version #452 for Trix but could find little about that. I think maybe it was similar to the 3-rail version except the wheels on both sides would insulated?

It runs well on 2-rail track and I've toyed on and off with the idea of conversion but realistically it does not look like it's practical or economic. Cheaper to change it for the factory 3-rail version #451, unless I wanted to go the whole hog and do this conversion from SB - yes it would be an awesome runner, and Digital, but € 137,00 ?? Phew that makes my eyes water.

So, I'm really just wondering if anyone else here has and/or runs one of these and what your thoughts are?

Some of the research I've done was interesting. Apparently the body casting is virtually identical to the Matchbox VW Bus and when that was discontinued Eheim got the rights to use it?

There is some chatter about them on other forums but I cannot find any deeper articles about them.

I believe they were produced from the late 50's to maybe mid-60's - I have only a couple of catalogue references for them but also a few links which I will add at the end.

Hmm, will that actually run on stud contact track? Looks like it is designed for solid centre rail.
I imagine it only runs forwards or the shoe would act like a ratchet.

Yes, it only runs forward, but it is indeed a cute little model.

I will take a look at my unit because I think it has a slightly different slider.

BTW, talking of unusual sliders, this early thing from HAG also had the reputation of provoking accidents. Wink

Actually, no. Contrary to popular belief, that's not the pickup shoe. This is definitely a 2-rail DC version

You'll notice it's offset - it's actually a contact shoe, much like is found on most HAMO Loco's, those are a small round button but do the same thing.

I think it's mainly a Fleischmann feature.

It runs forward and backward quick happily on the rails, I actually give it a burst now and then on a section of straight K-track which if not connected to any turnouts, the outer rails are not joined so can be used as a 2-rail test track as well.

The pickup does not hit the studs but I think unless the feature is specifically required, many users would simple remove the shoe to prevent any fouling on turnouts etc.

But the true AC version is noted as only running in a forward direction and I can only imagine this would be because a Diode/s was added to rectify the AC for the DC motor but of course nowhere to put a reverse unit.

That is another reason the SB kit would appeal, full Digital control. I'm warming to the idea but I did actually get a really tiny N-gauge DCC decoder which believe it or not, does just fit inside.

However I'd need to fabricate a proper middle-rail pickup from scratch anyway and still modify the chassis to be able to wire the Decoder in and I'm just not convinced it's worth all the hassle.

Plus, these little Draisine's still get a good price on ebay at times and if I jigger this one in trying to convert it then it's only worth parts value.

Here's a couple of images showing the original 3-rail AC version - the split pickups are the earlier design, and they also have the motor with the large brass worm-gear which also acts as a flywheel, really smooth running I believe

While cookee_nz wrote the above message, I was busy taking pictures of my Eheim unit. Wink The slider of mine looks like the one in his photo:

Thanks to this thread, I had to open the plastic box and saw that the foam inlay had started to deteriorate - phew, saved the little machine just in time! ThumpUp

Hi. I have one of these !
Many years ago I owned a classic VW microbus/camper - a 23-window Samba or Sondermodel.
I used to take it to classic car shows and when a local model shop gave me a catalogue which showed this model I thought about making a layout on the shelf above the rear engine and having a VW bus running on it.
Unfortunately it took me about 10 years to find a model and by that time I had sold the van.
My model is Eheim not Brawa but I understand that Brawa took over production of Eheim items such as the Trolley bus range and re-branded them.
The model has been in my display cabinet for many years but I just took it out and ran it on my test track and it worked perfectly !

I also collected models of VW vans and still have them and have a matchbox van but they are stored where I cannot easily get at them so cannot check that the body is by matchbox ( Lesney) but I have heard this theory too.

Regards, Colin.

I have had mine for about 30 years. As I recall, it contained a diode but no slider when I bought it at a swap meet.
I made up the slider in the photos by cutting two Marklin sliders and mounting them on a phosphor bronze spring with two arms.
Like Cookee I have a test track of K track which enables 2 or 3 rail running.
The sliders are longer than the distance between 2 centre studs so they don't drop their points.
I removed the diode and now run it basically 3 rail DC in both directions.
It will push happily over a C track point but I have never run it across one under power.

I like the original slider in the photos above.

Thanks Howard, nice job on the pickup slider ThumpUp

If it's no trouble, and seeing as you have it out anyway........ any chance I could ask you to "pop the hood", and take some photos of the internals, both sides etc, enough to hopefully see detail on how I might modify mine for analogue, AC.

Then I 'might' be encouraged enough to revisit my tiny decoder although I also have it in mind for a Faller AMS experiment BigGrin

Well now I am thoroughly confused.
My Eheim draisine had an internal diode but no slider. Years ago I removed the diode ( and now can't remember where it was attached) and ran it 2 rail DC.
I suspect the diode ran from the bottom tab of the brass frame up to the unused top solder tab.
When I opened it to take the photos for Cookee it is clearly a two rail version with the gear train and not the large worms gears.
Whoever owned it must have had a go at converting it to 3 rail but gave up or the shoe was unsuccessful.

The two wheel pickups are connected to the common tab at the top which is one brush connection.
The slider is screwed in the middle to the brass frame which holds the motor and the bottom brush is soldered directly to the frame.
This is seen( just!) in the third photo. The heat damage to the orange motor housing was not of my doing!
The profile shot is just to show the phosphor bronze arms coming from the middle of the contact. They are soldered to the centre of each pickup.

Cheers,
Howard.
