Hello guys...I need a bit of help here if possible.

I'm putting together a GE lookalike diesel, with the odd looking 'draught' [draft?] trucks.

Something like the EBT M-7?

I am struggling to find any drawings, or even, basic dimensions.

All I need for now is an idea of truck wheelbase, and the truck centres.

The rest I an work out...

Can anybody help?

Thanks, best

Alastair

OK, all's quiet on this subject, sooooooo......does anyone have any dimensions, at all, for GB&L #15/GLRX#15, that went to the Cumbres & Toltec Scenic RR?

I cannot seem to find any of these sorts of details, although plenty of photos, and some observations on other forums.

Truck wheelbase is the most useful.

Truck centers would be nice?

These trucks are coupled to each other, for heavy draft purposes [no draught forces going through the engine's frame]....so appear to have a longer wheelbase than normal road trucks.

There are similar types of machine that used to work at Bethlehem Steel's 3 foot gauge in Johnstown, PA...albeit probably not GE, but I cannot tell.

The C&TSRR # 15, and their # 19, which is of a similar parentage and type...[50 tonners]....both seem to have hailed from the Oahu Railway , out of US Navy.
Both, of course, 3 foot gauge.

I've searched via google, all of the above companies, links, etc...including TrainOrders.com....from whence I obtained a little of the above information.

Are these locos still at the Cumbres & Toltec? [They certainly 'appeared' to be?}

Does anyone [in the USA?] have any pointers as to where basic dimensions may be found? [As some may know, I'm in the UK, much to that sturdy State's dismay.]

Looks like that way indeed....

Seems that, certainly in the UK, every oddball industrial loco has been measured and poured over to the N'th degree....?

Maybe I need to find out how to work search engines a bit more effectively?? :)

I wish you luck, I would like to see what you come up with.

I believe the Durango & Silverton's PB #1 may of came from the EBT or at least was the same design. That was sold to the Colorado Railroad Museum in Golden. Might be worth a try to contact them, maybe you could con someone there into taking some measurements for you. Another place to try is the Narrow Gauge Discussion Forum, a wealth of information and I know there are CRRM folks that read and post there.

I remember these trucks were very simple design and were made out of steel plates about 6"s thick for tractive effort. I do have a PDF of a scale drawing of the GE 44 ton if that would be helpful. PM me if you want me to send that to you.

Cheers and good luck!

I did find this http://www.pell.portland.or.us/~efbrazil/ge_coop_2_draw.html

And according to this website, http://www.spikesys.com/EBT/Loco/ it may be classified as a 47 ton but that is not definitive. I believe when these were designed, the was some rule about having a fireman on diesels 50 tons or greater.

I thank you for the links.....just what I wanted.

I've also been inspired to look at the GE U6-C as well...in narrow gauge form.

Yes, the GE 50 tonners were in reality slightly less heavy, probably for the reasons you quoted.

These locos moved around a lot. C&T has/had one, which came from the Georgetown Loop railroad, out of Oahu Railway & Land, ex-US Navy.

Some came from Canada Steel {?}, and from other steelmaking concerns.

Bethlehem Steel had some similar locos [albeit heavier] on their 3 foot gauge systems....and not all of them seem to be GE either.

The common denominator with all these locos is the truck design.
Designated as 'draught [draft]' trucks, they are, as you note, very heavy, and actually coupled together underneath.

The loco bodyshell & frame would be perched on top.

In my mind, these factors give these locos a unique appearance in the diesel world....and mostly being narrow gauge too.
[Almost like having a couple of GE 25/35 tonner 4 wheelers coupled together, with one bodyshell between two?}

I've also re-discovered the Edaville BB diesel in an ancient RMC...of which I have too many.....they take some trawling through!

So that too, would be a good use for various GE-type bodyshells, but for 2 foot gauge!!

I don't think I'll be trying to produce any exact replicas at present...more like 'models inspired by'?

Incidentally, in the very large scales, drivelines can be prototypical, as the trucks had one traction motor each, the other axle being chain driven!

I am a bit surprised the GE 47/50/55 tonners with the strange trucks haven't appeared much in the RTR market

After all, a lot of US preserved narrow gauge RR's found them very useful workhorses, even substituting for failed steam locos.

Maybe they're too ugly? :)

I came across another link that lists the models built for each railroad

Thanks for that link, Patrick....very useful....there appear to have been a lot more narrow gauge versions about than I first thought? :)
