Diesel engines are way tougher to maintain generally needs to be by specialized heavy diesel mechanics. They also need more frequent overhaul over the service life. For regional passenger moves and short haul, battery trains are more viable than hydrogen in the medium to long term. Hydrogen requires specialized containment and a lot of specialized infrastructure. For long haul freight (> 100km), hydrogen could be viable possibly, but electricity is still much lower opex that would offset the higher capex.
The maintenance nightmare is the main problem on any long track. Electric trains are fine within a municipality because it is short distances and frequent stops. For a Go train that goes from Barrie to Toronto traditional rail is the only thing that makes sense. We are running out of diesel globally, our total fossil liquids production is on pace to be 60% lower by 2050. With every 5% reduction in oil production prices go up 50%. As you may have noticed it starting with Hormuz. Which is still being mediated by reserve releases But if Hormuz stays closed for 3-6 months we could see prices rise 200% to $3-4/lt
Do you know the distance between Barrie and Toronto? It's about 80-100km. Hamilton to Toronto (the most populous corridor)? 60km. As far as train tracks in Canada go that's pretty short.
Caltrain did it between San Jose and San Francisco (75km) for 2.5 billion USD which is a major capex but their operating cost for fuel and things went down were 20-25% less than initially expected, even if in absolute terms the O&M budget went up, but the service became more frequent, fast, reliable, and so the operating cost went down per trip and per rider compared to its post-COVID diesel days.
