The aim of the article is to present results research and modelling wheel set wear on rolling diameter drive wheels a multi-unit traction unit. object was PESA ELF I electric multiple unit constructed as five-unit based two end bogies three central bogies. presents change in recorded every months during periodic inspection over period five years vehicle operation until revision repair. Based tests, determined, basis which function time mileage modelled. models, mileages expressed kilometres were determined for each with longer operation. reason implementing subject uneven individual units. maintenance system documentation requires that after specified time, e.g. 5 years, sent repair, even if none sets has reached limit.
