If the monomotor truck is a problem, then why does it work so well  
all over Europe?

It wasn't the problem.   You have to remember, Jim, that press  
releases are documents issued to cover up something that a  
corporation or agency doesn't want you to know and divert attention  
to something else.    A monomotor truck requires that all wheels be  
the same diameter or it will put undue wear on the gear boxes.   When  
PAT failed to properly maintain the trucks, i.e. by changing one  
wheel set and leaving the other worn, then their answer was to blame  
the manufacturer for his 'poorly designed' truck that worked  
perfectly well where it was maintained according to specifications.
