Note that in the F9 display the B17 loco is facing in the wrong direction. Also note that the highlighted coupling in this display is the coupling between the two locos and the text for this states that it is of a type which cannot be uncoupled.
On investigating I concluded that the sim has inverted coupling characteristics of the B17 loco and the coupling I am trying to uncouple from it is the bar coupling which, if all is read correctly, should be at the other end, coupling to the tender.
The following two additions test support this:
1. I can, without problem, uncouple the B17 from its tender, although both of these are, if correctly read by the sim, bar couplings.
2. If I temporarily edit the B17 .eng file to put the bar coupling second and rerun the scenario, it still shows the wrong way round in F9, but is able to be uncoupled.
Is this the cause of some of our front coupling problems?
