This Kato EMD SD90/43 MAC was a thank you gift from a friend. I have not unboxed it yet but want to know what is the best radius curve for this engine. On my layout I am using 18" radius and I think it is too short. Most of my engines are gp9's & 30's. The engine is a beauty though.

Just my opinion but I think a loco has to not only negotiate a curve , but not look " toy like " in doing so . I think a 36" curve would be necessary if it was my loco ( but it's not mine )

Nice friend! I hopeit runs well on your layout!

They recommend a 24" radius.
I tried to run my Kato C40-9W on 18". Wasn't happening.
