Abstract

The invention relates to railway switch management. Data are used to calculate one or more of the quality numbers Q5, Qcp and Qj by using the following formulas: <DF>Q5= (1-0,1*Qg)*(1-0,1Qc)*(1-0,1Qt)*(1-0,1Qv)*(1-0,1Qh)*10; </DF> <DF>Qcp=( SIGMA Npcp/ SIGMA Nmcp)*10; </DF> and <DF>Qj=(0,5*Sg+St+Sv+Sh)*10/3,5*Rj, </DF> the result of which is possibly combined with one or more of the results of the following formulas: <DF>Qv = L - Ä SIGMA (D*F)/ SIGMA FÜ * L </DF> <DF>DI = D * F </DF> <DF>W =Ä SIGMA DI/ SIGMA FÜ * L </DF> <DF>Qv = L - W </DF> <DF> DELTA Qi = DELTA Wi =ÄFi / ( SIGMA F+ DELTA Fi)Ü*L </DF> into a quality level that is compared with a predetermined target quality level, and it is decided to carry out predetermined maintenance activities when a predetermined maximum difference from said comparison is exceeded, to improve the quality level of said switch. Also a measuring vehicle is proposed provided with sensors to measure one or more of the following parameters of a switch: gauge, cant, gap width, vertical and horizontal irregularity.
