Choyamba, mayiko atsatira mfundo imeneyi popanga njira yoyendetsera njanji: mzere wa msewu wa njanji umagwirizana ndi kukula kwa msewu wa gudumu momwe angathere, ndiko kuti, kukula kwa msewu wa njanji, monga msewu wa 59.9kg/m ku United States, mzere wa msewu wa njanji umagwiritsidwa ntchito pa R254-R31.75-R9.52; msewu wa 65kg/m wa dziko lakale la Soviet Union, mzere wa msewu wa njanji umagwiritsa ntchito R300-R80-R15; msewu wa UIC wa 60kg/m, mzere wa msewu wa njanji umagwiritsa ntchito R300-R80-R13. Kuchokera pamwambapa, tingaone kuti chinthu chachikulu chomwe chimagwiritsidwa ntchito popanga msewu wamakono wa njanji ndi kugwiritsa ntchito ma curve ovuta ndi ma radii atatu.
