At zero speed the friction values of the first two ES44s are by way of the older code using ORTSBearingType ( Low ), which looks reasonable for such a modern engine. the third engine uses the two new lines as described before.
--212.5 us tons in weight / 6 axles / 13.24 square meters of frontal area / modern roller bearings
The three Davis lines are the same with all three engines. All six lines at once
ORTSDavis_A ( 2606.907023 ) ORTSDavis_B ( 31.875 ) ORTSDavis_C ( 1.607582 ) ORTSBearingType ( Low ) ORTSStandstillFriction ( 3506.25 ) ORTSMergeSpeed ( 0.870116 )
Here the train just met the merge speed of the third engine, lower than the ubiquitos 5 mph of old; ORTSMergeSpeed ( 0.870116 ) means about 1.9464 mph. The values of the other engines are still on their way down...
Above 5 mph all three engines behave the same as they have the same Davis values (though the first has frontal resistance).
