No, you can call yourself whatever you want. A janitor can call himself a "custodial engineer". You're probably thinking of the "P. Eng." designation beside your name.
Ash is right, in Canada, you can't state that you're an "engineer" without being accredited by a provincial body, at least in Quebec it's pretty strict. However, it doesn't matter in the context of this article and it shouldn't detract from it either.
Really great stuff and nice hear about a career move that made you happier :)
On passenger trains what are the people taking tickets called then? I've never heard the person driving the train to be called a conductor before since that's usually (at least in US terms) a demotion for them.
