il peso del treno non conta!!! contano gli assi motori!! se il treno è piu leggere funziona meglio!!!
Il treno in base al coefficiente di attrito tra ruota e rotaia puo superare un certa pendenza, dopo si deve ricorrere a piu assi motori.

l'ultima volta che l'ho studiato il coefficinte di attrito era funzione dei materiali in contatto, e l'attroto in funzione della forza normale sul punto di contatto (quindi in funzione del peso)...
