OpenRails carriage files

I have been updating my TrainSim installation to make use of the OpenRails eng and wag files often now included as an option.
I have noticed that quite a few coaches, notably the ex-LMS bogie coaches in BR livery , have the number of wheels defined as 4 even though they are bogie vehicles.
Does this matter?

NumWheels ( ) is an MSTS misnomer. It really means number of axles - so four is correct for a bogie coach.

If you are updating to OpenRails parameters you might want to use ORTSNumberAxles ( 4 ) as in the example below.

Thanks. I suspected as much seeing that they seem to work fine.
