Why Train goes slower on the corners of curve?

Hi everybody. I have a problem. Could someone help me about that please? Why Train goes slower on the corners of curve?
I create a reference curve for train road. And I used Joint Tool to rig my train. And than, I used IK Spline Handle Tool to attach my train on my curve. But when my train goes on the corner of curve it is getting slower. Why? I have rendered it but result was not changed... Thank you... user added image

It is most likely caused by the fact that the CVs are closer together in the corners than on the straight bits. A quick way to get around this would be to rebuild the curve with uniform parameterization. See https://download.autodesk.com/global/...uild_Curve.htm

Imagination is more important than knowledge.
