Choyamba, mayiko atsatira mfundo yotereyi pakupanga njanji yamutu wa njanji: arc ya njanji pamwamba pake imagwirizana ndi kukula kwa gudumu momwe zingathere, ndiko kuti, kukula kwa arc, monga 59.9kg/m njanji ku United States, arc mutu njanji amatengedwa R254-R31.75-R9.52;njanji ya 65kg/m ya yomwe kale inali Soviet Union, njanji ya njanji imagwiritsa ntchito R300-R80-R15;UIC 60kg/m njanji, mutu njanji arc utenga R300-R80-R13.Zitha kuwoneka kuchokera pamwambapa kuti mbali yaikulu ya mapangidwe a gawo la mutu wa njanji yamakono ndikugwiritsa ntchito ma curve ovuta ndi ma radii atatu.Kumbali ya mutu wa njanji, mzere wowongoka wokhala ndi nsonga yopapatiza ndi pansi waukulu umatengedwa, ndipo otsetsereka a mzere wowongoka nthawi zambiri amakhala 1:20 ~ 1:40.Mzere wowongoka wokhala ndi malo otsetsereka nthawi zambiri umagwiritsidwa ntchito kunsi kwa nsagwada ya njanji, ndipo otsetsereka nthawi zambiri amakhala 1:3 mpaka 1:4.

Chachiwiri, mu zone kusintha pakati panjanjimutu ndi chiuno cha njanji, pofuna kuchepetsa ming'alu yomwe imayambitsidwa ndi kupsinjika maganizo ndikuwonjezera kukaniza pakati pa fishplate ndi njanji, njira yowonongeka imagwiritsidwanso ntchito m'malo osinthika pakati pa mutu wa njanji ndi chiuno cha njanji, ndi lalikulu. mawonekedwe a radius amatengedwa m'chiuno.Mwachitsanzo, njanji ya UIC ya 60kg/m imagwiritsa ntchito R7-R35-R120 m'malo osinthira pakati pa njanji ndi chiuno.Njanji ya ku Japan ya 60kg/m imagwiritsa ntchito R19-R19-R500 m’malo osinthira pakati pa njanji ndi m’chiuno.
