Rant ... I ordered a string of 6 Bachmann V-dump ore cars to go behind my LGB Diesel switcher. I have seen the ads for these things forever, and thought I knew exactly what I was ordering. Yes, they are labeled 1:20.3 scale ... but I still pictured them as being rather small. I was shocked when I opened the box. These things are 6 1/4" wide! A quick and very short run out on the layout proved that they won't even fit through my tunnel portals and they look way to big behind the LGB switcher. (They do look OK behind a Shay.)

While I will concede that this is my fault, I think it would never had happened if the manufacturer could have just provided the slightest bit of information, i.e. specifications, for the product, like dimensions? While scale of 1:20.3 is a clue that this might me something larger than something in 1:22.5 scale, it doesn't tell me how big it is unless they provide the dimensions of the prototype. The near total lack of specifications for large scale products just continues to urk me!/DesktopModules/NTForums/themes/mls/emoticons/angry.gif" border=0>" /DesktopModules/NTForums/themes/mls/emoticons/angry.gif" border=0>"\
This is the type of thing that can really burn you ordering on the web, compared to your local hobby shop. See it, touch it, feel it.

Those suckers are huge. I use them for 7/8's (1:13.7 scale) and they're even a bit big for them.

These figures are nearly 5 inches tall!

Del,
If you had a PDF file for them, you could tweak the dimensions to get exactly what you want!
About the only thing those cars look right behind is the 1:20.3 45 tonner--it may be scale, but it dwarfs everything else on the RR. Had to get one, anyway

Further to Brian...

Yeah, even us 7/8ers were shocked. Luckily we had early warning from one of our brethren.

I've seen hundreds of skip photos and never seen any prototype that large (bet I will now). No idea why they made them so gargantuan.

A quick touch of the caulculator reveals that they scale out to 10' 6 7/8"

That's as wide as, or wider than, modern standard gauge rolling stock!
Was there really a 3' gauge v-dump that was over 10' wide? Or was this a fictictious creation of Bachmann, labelled 1:20.3 to make people think it's suitable for a scale railroad?

I was also very surprised at the size of these cars, but the chassis is so good I decided to cut mine down and now I am very pleased with them running with my Accucraft C16.

I was unable to locate a pic on short notice but ...

I believe these cars are quite prototypical for modern (post 1970) open pit quarrying operations. I have also not checked my references for South American or Chinese ng but I doubt that such wide cars were used in regular mainline service. To give a sense of what we are looking at, consider the size of the dump trucks used in offroad open pit mining.

B'mann hasw a penchant for producing unusual stuff especially in the industrial field. Since most large scale modelers are not very familiar with industrial equipment (beyond logging locos) it would help if they would publish some dims with their ads. At least they published the scale which is more than most advertisers publish.

As an aside, most folks are very conditioned by the use of 1:22.5 or smaller scale combined with the choice of puny prototypes and often models shortened from the prototype. These same people are amazed at the size of a K-27 even though it is a small loco by sg practices and only the next step in modernizing had American ng survived in a viable commercial form. F scale is big ...

Regards ... Doug

David,

How did you cut them down?

I cut about 5/16 inch off the top of each side with a razor saw and then glued 1/8 inch plastic angle to the outside of the cut edge to form a new lip. The tipper buckets were then sprayed with matt grey paint and touched up with spots of rust colour paint.

I have a rake of 9 of the hoppers and so sawing them all by hand was a bit tedious, but once done I was pleased with the outcome and they now fit all my tunnel entrances. They ride the track really well - I think due to the very nice heavy metal chassis.

I bought one of these cars in Fall of 2006. As others have posted, I was astonished at how large it was. I added the larger diameter wheels to mine and mounted the Kadee 830 coupler boxes to the top of the frame. This way it looks appropriate with the 7/8ths inch scale whimsical locomotive I use to pull it.

I may eventually get another car to modify in the same way. The cars really seem to fit with 7/8ths inch scale equipment best.

Yours,
David Meashey

Thanks for the tip David. I am in the process of cutting one down now. Looks like it will work out fine.

And as an added benefit, my rotary tool, a Black and Decker "Wizard" bit the dust, so I went out and bought a real Dremel tool. I started out using a razor saw, but I think the Dremel with a cutoff disk is going to be easier. Just hack it off then clean it up with a file.

All sounds logical, Doug. But like flying saucers and bigfoot. I'll believe it when I see some photos.

:D
