Yet, the more I look at this whole Metrolinx-Georgetown Corridor-Fixed Link to Pearson contretemps, the less I can stay silent on the matter. The main sticking point, the only sticking point, the entire enchilada is the matter of diesel. I mean, WHAT?!?!? How backward thinking is the brain trust at Metrolinx and its overseers at Queen’s Park? Diesel?! Really!!? Why not just swing for the fences on this and step right into the way back machine and decree that we’re going to de-mothball the old Iron Horses?
Has no one at Metrolinx taken a moment to look around the world and see what’s going on in terms of train travel? China, that old emission spewing, polluting boogeyman that’s still technically speaking a developing country, just unveiled the world’s fastest passenger train that runs basically off the electrical grid. Nevermind their electromagnetic Maglev trains they use for shorter hauls. Japan and Europe have been operating high speed electrical trains for decades now.
Cue the start of the second decade of the 21st-century and we here in Ontario, unveiling our biggest public transportation expansion in decades, are hitching our wagons to diesel. It is more than mystifying. Nonsensical doesn’t describe it. Unconscionable barely does it justice. Flat-headed, myopic, lily-livered, atavistic, primitive beyond the pale only begins to scratch the surface.
Money, they say. We don’t have enough of it to electrify the corridor. The people at the Clean Train Coalition disagree. Using Metrolinx’s own numbers, they contend that going electric from Union Station to Brampton will cost only 17% more than the present plan, some extra $150 million. On top of which, electric trains are cheaper to operate than diesel and the extra money it’ll cost to set up an electric system would be recouped in 10 years from operational savings alone. 
And frankly, I don’t buy into the assertion that it’ll be diesel initially and then electric down the rails sometime, let’s say 15 years. First off, once you’ve fully entrenched one system, the sheer weight of inertia will make it that much more difficult to jump tracks (the puns are almost involuntary). I mean it’s taken 30 years just to get around to this kind of talk about transportation infrastructure expansion. Secondly, what’s the economic sense to be spending some $1 billion on diesel only to pledge to redo it all a decade and a half later?
Financial jockeying aside, it’s just seems like further proof that our leaders have their heads firmly planted up their asses while sitting down in the sand when it comes to looking into the future. We’re coming to the end of cheap oil, gentleman. We should be weaning ourselves off our dependence on fossil fuels. 
Without even getting into to the health and noise pollution arguments – we’re talking a substantial increase in train traffic affecting some 300, 000 people – there’s other mitigating factors as well. Electric trains are faster. They can stop more often than their diesel counterparts. And, for a train buff such as myself, they are far more aesthetically pleasing. They look cool and have better names.
So what exactly are the benefits of the diesel train aside from a lower initial cost? They already exist? Well, sort of. The highly touted (at least by Metrolinx and the provincial government) Tier 4 clean diesel technology is very new and not yet thoroughly tested. So its air quality claims cannot be viewed as rock solid. Furthermore Steve Munro, as unbiased a public transit advocate as you might find, questions the passenger load numbers that Metrolinx is throwing around in terms of exactly how many cars the Georgetown expansion will remove from the road as drivers start to take the trains.
The unfortunate fact of the matter seems to be that after years of inaction that has allowed this region’s public transportation system to fall behind those of some 2nd world countries, we are now scrambling to simply catch up to where we should’ve been two decades ago. Exhibiting a continued lack of boldness, initiative and vision, those at the helm of the transportation expansion are threatening to leave us at that exact spot. Twenty years behind the time.
