Europe has trains deeply embedded in its DNA - the system is a marvel, and a Europass will get you from one end to the other at 300Km/Hr no sweat !
And this merger example is no surprise - or should not be ! Such high tech capital intensive industries need global scale business to survive and compete. And perhaps this will be a wake-up call to the China "slave labor sweat shop" propaganda crowd !
The far deeper concern ? Consider that our current political establishment is agitated over taxing small businesses even more, or raising minimum wages by 30%, exercising their mind over pronoun biology and the mental health issues induced by the teaching of Discovery Math  .-( 
As for establishing global scale successful businesses - someone might become "rich" - and will therefore be taxed into submission before such a happy state of affairs perturbs our wimpy socialist DNA.
Methinks Canada is in deep DOO DOO !
