Stolräler / dubbelhuvade räler -- vändbarhet? (Bana)

av Anders Järvenpää, Thursday, May 06, 2021, 13:19 (1474 dagar sedan) @ Christer Brimalm

De nya stolrälerna vid SDR förefaller inte vara vändbara.

Nya stolräler 2021

Vad vet vi om vändbarheten gällande stolräler? Jag har kanske missuppfattat saken men jag har levt i tron att man brukar valsa stolräler med en symmetrisk profil så att rälen kan vändas uppochner när huvudet som pekar uppåt har blivit utslitet.

Om jag inte minns fel har jag sett stolräler även i Frankrike.
