Choyamba, maiko atsatira mfundo yotereyi popanga njanji ya njanji: arc ya njanji yapamwamba imagwirizana ndi kukula kwa magudumu momwe mungathere, ndiko kuti, kukula kwa arc, monga njanji ya 59.9kg / m ku United States, arc mutu wa njanji imatengedwa R252-R39. 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 imabwera chifukwa cha kupsinjika maganizo ndikuwonjezera kusagwirizana pakati pa fishplate ndi njanji, phokoso lovuta limagwiritsidwanso ntchito m'dera la kusintha pakati pa mutu wa njanji ndi chiuno cha njanji, ndipo mapangidwe akuluakulu 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.
