I am sorry to say the opposite, but km / h and kN are used on Eastern European railways. Many Czech, Slovak and Hungarian locomotives use the ORTSTractionCharacteristics table where km / h and kN are given. 0 - 200 km / h in 2.5 km / h increments per line. We have an electric locomotive that has 36 gears. The 81 × 36 data that should be overwritten. I make such tables myself so I protect this value.

Laci, ( I beg your pardon, but I believe you are missing an essential point of the discussion ). We all realize that different geographic areas use different units of measurement in their tech documents, specification and working manuals...however, OR as a matter of design principles has adopted the SI UoM ( International System of Units -- basic & derived units ). In the case of the ORTSMaxTractive curve set the correct SI UoM would be m/s and newtons...which would not have to be expressed after the values. All other units accepted by OR would have to be placed immediately after the values for correct interpretation. km/h and kN would be accepted, but would have to be written after the values in the table. In the US you find many manuals with mph and foot lbs of force.
All this is outlined in Appendix 22.1 in the manual.
