I am thinking of buying a usa trains gp38-2 dose anyone now what the minimum size curves they will run on. My main line is aristocraft second radius curves any info is much appreciated.
Thanks Adam
 
I think you'll find it's 8ft diameter as a minimum - what is Aristo second radius, is that their 10ft diameter? if so, all OK
 
What a beauty! What livery are you hoping to get?

There's no mention of minimum radius in the manual:

As it is only a Bo-Bo I'd be inclined to believe the 5' radius you found in that DCC wiki document, but obviously you would prefer someone who has first hand experience.

Are you buying it from a retailer? Could you take some curved track along to try it out?
 
BTW I think they come DC only and you have a DCC layout. Has it been chipped or are you planning to have a go?

They are DC only... And NOT DCC friendly! - Can be done, and there are tricks of the trade to make it easier..
 
It is dc so I would fit a decoder but it is new effectively no sound. So I would wire the decoder so it feeds the original board with motor output from the decoder so lights and smoke will work like in its original dc form.
That was my plan anyway.

DC USAT GP-38-2, Santa Fe red warbonnet, was my first loco. before I even had a line 16/17 years ago. It was shelf queen for my first 2 years of ownership. Then I thought.............rest is history. Great little loco.

Mine ran happily through R3 points and even a reverse curve made of R3's. It ran with a mix of USAT, Accucraft,Bachmann and LGB US outline stock, with knuckle couplers fitted. Nostalgia binge over. Max
 
My point of view :
GP38-2 runs fine on R1.
However I think I am happy with it because I have hook and loop couplers.
With some cars I need to have only one hook behind the GP38.
With other cars I take care to have the GP38 hook outside the curve.
This is due to the overhang.

For sure if you have all the space you need, R2, R3 and beyond are better as stated hereabove.
 
I would not run it on R1, like the F3, it might make it, but really typically binds the trucks.

Here's a page on couplers, weights, modifying for prototype height, etc:

Also, USAT locos are really easy to DCC the track pickups and motors, get a few JST connectors and can be done in 5 minutes, takes longer to remove shell, but lighting is another matter, pull out the bulbs and make all LED.

HJere's a page on USAT DCC installs, including the "quick and dirty" DCC install: USAT DCC installation techniques

Like I say my main line is all aristocraft r2 so I should be okay and all my stock has hook and loop couplers so that should help as well
