Hi
before I went to 0f12, I start to build an 0e (0n30) Railcar, and I'm about to finish it. First idea was to use a Fleischmann Magic Train coach, but then I build it completely from scratch. Design was made step by step while I build, and so some pieces I must make two times ;) Chassis is from a german 4axle H0 switcher.

Here is the pic:

Maybe this green :bg: ? This was the first "mockup" with the original Fleischmann coach, now I want to use it as trailer, and the railcar will get the same color:




I'm thinking about some thin beige lines...

Michael,

I really like the effect you have created. It will look great as a Rail Car and trailer.

I would go for a deep red with beige lines.

Cheers

Thanks to all for the kind words :Woohoo:
Green or dark red, thats the question, or like George W. says: Everyone has a decision to make.... :Hmm:However, at first I still must do some work on the body, prepare the glazing, handrails, stairs etc. Stay tuned...:)

Breakin news ;)

Martin from Kalles german forum like the railcar so much, as he build his own - and he was faster as me :shocked::bg::

http://www.kostenloses-forum.com/board/triebwagenprojekt-,nxu,01642644nx1878,t,1931,start,30.html#15648

So I hurry, and here is the next step:





Decision of color was easy, because I hadn't a suitable green on hand... I will still make a thin yellow line under the windows and a black line at the bottom including the steps. Roof is not fixed also. And who had his greasy fingers on the front???:old dude:

It is a honor to have someone like your work so much that they copy it!

You have made a nifty little railcar that you can be proud of. :apl::apl:


Please send another photo when you are finished-

Of course I'm proud, and I like the "little blue brother" :bg:. We have planned a meeting of the railcars... maybe in September at KS Modelling Days in Stromberg.

Nearly finished:



To Kalles meeting in Stromberg are only few days left... so I keep up the work on the railcar to finish it.  The yellow and black stripes are wet transfer decals, Horns and exhaust I made from round acryl bar and brass wire, wipers and doorknobs are commercial parts. Driver figure and lettering still left, and maybe some bodges are to hide ;)

I reckon this would have been worth seeing.

I've always liked small railcars - and these ones look great.

 

Recently, I've been checking the internet - I've been trying to find out about some real railcars, built in the 1930s by Triebwagen und Waggonfabrik Wismar:

http://www.flickr.com/photos/railbus/4014835378/in/set-72157622717748275/

http://en.wikipedia.org/wiki/Wismar_railbus

 

The unusual thing about these iconic railcars is that they have engines at both ends - only one is used at a time.

A number of German manufacturers produce models (or kits) - unfortunately, they're all rather expensive. This has got me thinking (often dangerous).

I don't know if similar vehicles were built elsewhere - if they were, this might mean that a freelance kitbash could be credible.

I guess I'll never find out - so I might just have to use up a few bodyshell scraps (and bits of plastikard, etc). I might also need to spend some drawing up plans in Illustrator - well, it certainly beats watching the "festive" turkeys on the television!



Regards,

Huw.

Huw,

here are some pics from the "railcar-meeting":




Martin had his layout exhibited at Stromberg, so it was easy to "arrange" some photos.



Another nice model: Thuri from Switzerland with his green freight railcar, the trucks with the siderods are from a Electric loco in H0.



If you need sketches from Wismar railcars, you can found two of them here:

Michael,

Many thanks.

The photos are great - and the models and layout look good too.

The drawings are superb - and they'll be extremely useful to me.

Thanks for your help.

All the best,

Huw.

Face it guys, anything with flanged wheels and a name like "Schweineschnäuzchen" just HAS to be modeled!

As has anything with 2 hooded Ford AA or BB engines, known as an "anteater" - but I'll probably still end up making a "pig's nose" of it.

Joking aside, Michael's drawings link is greatly appreciated - and means I can shunt the freelance "twin schnozzer railbus" concept into a siding.

The homebrew idea might have been fun while it lasted, but the real Wismar design just oozes character and class. That's why I like the things.

I particularly like the chassis drawing - helpfully ready scaled for Om or (in my case) Oe. With the "body on" drawings on the website (and in a book), I think I've now got enough information to start making plans.

Anyway, I think that's enough from me for the time being.

Regards,

Huw.

I printed out the drawings from Michael's link also, but after looking at them I realized that with something like an 11 1/2 ft wheelbase, it probably would climb right out of my overly sharp curves.

And with all that overhang, anything in the area outside of the curve would be swept away.

Still a great looking little car, and having spent a lifetime fooling with Model A and B Fords (and the AA and BB trucks), I am in a quandary as to whether or not to "put it on the list"

Herb,

take a look at the first drawing - there aren't platforms beside the hoods. This will maybe solve your problems with the overhang/clearing space.
Btw: every "Schweineschnauzchen" was unique, there are not two perfectly identical ones - serving to customers wishes aka freelance prototyping :bg:

It looks like Hornby might have been expecting similar issues with their OO Pacer railbus model:

http://static.hornby.com/files/ss-233c-class-142-railbus-361.pdf

http://static.hornby.com/files/hss-319c-class-142-railbus-dcc-456.pdf

It's very noticeable that their service sheet refers to a "motor bogie assembly" - replacing the front screw hole on the chassis with a curved slot (and possibly changing a few clearances) would allow the motor subframe to move freely on corners.

A similar arrangement is often used with RTR long wheelbase 4 wheel wagons - and also bogies on RTR steamers.

Saying that, the standard of the engineering in some of your other models suggests to me that you might not be the world's greatest fan of some of these work-rounds.

Regards,

Huw.

Huw-

Very interesting! This gets into the same problem that street cars (trams) encountered in this country. It was desired to extend the wheelbase of two axle units to give less fore/aft pitching, and also to accommodate more passengers. Most cities had curves as sharp as 36 foot radius which meant that the was a limit of about 8 ft wheelbase for two axle cars. There were several ideas tried- one the Robinson Radial truck (bogie) a three axle unit which used the offset of the middle axle on a curve to steer the two end axles radially. Robinson's advertisements showed how the axles conformed to the curve perfectly--but they fought each other when passing from tangent to curved track. and vise-versa.

Another try was made by the Brill company which stayed with two axles, that could displace radially, but in doing so lifted the car body slightly because the axles moved up a slight ramp when they were other than parallel- thus the weight of the car tended to keep them parallel.

This was the crux of the problem-to allow the axles free enough movement to conform on a curve, and yet try to keep them from "hunting" on the straight.

At one point in time, my sons and I built a 7 1/4" gauge railroad behind the house. One curve was particularly sharp, out of necessity. A "diesel" very much like the current Ingersoll-Rand had no problems with this, pulling 40 (scale) foot cars. I got the itch to build a model of a Brill railbus- a gasoline powered unit with a bogie in the front, and a single fixed axle in the rear. I built a powered "mock-up" to see if there was a problem with this configuration, and was surprised, and pleased, to find none. When I built the chassis for the model I noticed that I had made the mock-up wheelbase one (real) inch too short, which I corrected, and the chassis would derail on the outside of the curve every time- the rear wheel would climb the outside rail. I cured the problem by making  the front bogie steer the axle through linkage.

I wonder how Hornby has tried to keep the axles parallel? Seems like all there is is a pivot.



Enough "blather"!

Herb-my little Model T railcar had the same problem. It has a 2 axle lead truck and single rear driver which tended to derail to the outside of sharp curves (all there is on the MRy). The "solution" was to make the rear driver pivot slightly and that cured the problem. The driveshaft is similar to a Shay or Climax which has sliding box joints and universals. Now the supt. can inspect at will without jumping the track and racing (at 5MPH)  across the scenery.         Woodie

All of this stuff is of great interest to me, for a couple of reasons.



I've mentioned about the Hornby model of a Class 142 "Pacer" railbus.

What I forgot to mention was that, in some parts of the UK, the real things became known as "skippers" or "nodding donkeys" - these names are actually far too polite, as they are notorious for poor ride quality.

This isn't helped by the fact that they run in pairs - so, even if one of them actually wants to run properly, it gets pulled out of true by its partner in crime.

I don't know who had the "brainwave" of putting pairs of hacked-about Leyland National bus bodies onto rough 4 wheel chassis - and thrashing the resulting contraptions along the same tracks as proper trains. All I do know is that I wish they'd keep their "bright ideas" to themselves in future.

Class 142s are also notorious because their wheels start squealing loudly the moment the things go anywhere near a curve. This is unfortunate - as they are often used in hilly areas, with lots of tight curves. They might look pretty, but you can hear them coming!

In the former East Germany, I believe that some 4 wheel railbuses acquired a nickname which roughly translates to "piglet taxi" - while their "modern" British equivalents just seem to squeal like pigs. I've been told this is called progress.

In view of my obvious dislike for Class 142s, you might wonder why I'm so keen to build a model of a Wismar railbus. Well, I'm not planning on (ab)using it in the same way as the real 142s. I'd just like to see 1 railcar trundling along sedately every now and then - maybe even just sat quietly somewhere - so I can look at it and think: "I built that". Strange perhaps, but I just like the way they look.

 

Personal opinions aside, the real reason this stuff interests me is that I'd like to avoid the problems that have been flagged in this thread - but I don't have space for large radius curves. I think I might be working on "test hacks" before I even start on a model. I'm glad I enjoy technical challenges.

 

Regards,

Huw.

The story continues... A fellow modeller asked me for a model of the railcar, and I felt like having another, different one for me too.  Walls from teakwood maybe? Tempting... So I made the drawings and send them to my lasercutter. This is the result so far:



inner body with interior



side view, second cab still missing



front view

The assembling was quite difficult: The birch plywood warped during the staining - although I treated both side - and there was no chance to hide a bodge or fill a gap with putty.  So I reinforced the cabs with sturdy frames from .060 plywood and the sidewalls were stabilized by the inner body. The mitres were hand filed and adjusted to each other. Some edges need a bit of staining, but I'm pleased with the result so far. Now comes glazing, wiring, illuminating, the housings for the headlines will be made from styrene tube.

Are you going to leave the exterior as varnished wood?

Yep... according to some swedish and brazilean prototypes which were panneled with teak wood.
