Just think. An unattended train of 100 oil tank cars rolled uncontrolled in Quebec. The derailment and following fire wiped out half a town and killed over 40 people. It was the worst disaster of it's type in Canada. Now we have hundreds of thousands of these cars rolling out of Alberta every week. I personally think a pipeline is way safer and cheaper to operate than moving millions of tank cars every year.
It's for pulling special Schnabbel trailers that handle 400 to 800 ton loads. Even with such an extreme heavy moving companies like Mammoet, they will use two or three pullers in the front and three and four in the back for safety going down slight hills. Just like a large train you got to use multiple locomotives.
How do they shield the electromagnetic elevators and catapults from prying enemy ELENT aircraft and drones? We will probably never know and that would be a major concern for the world's first stealth aircraft carrier.
People are more true to you when you are first true to yourself. Some guys wear it well some don't. You have it right and it works. The cap just ruins it for you unless you are handling food or working with dangerous machinery.
That red schnabbel car reminds me of CTX800 that I encountered one late winter up north of Edmonton. It was transporting a 900 ton manganese pressure vessel to Fort MacMurry Mildred Lake for Syncrude. It would be impossible to move such a load in the summer as the ground would be too soft.
These would be really deadly if they are nailed by a pickup or SUV which is very common in North America. I never heard of a Smart Car involved in a collision in Alberta but you can guarantee there would be fatalities. They are great for European city roads where everyone one drives small cars but everyone drives pickups or SUVs. Size does matter in a vehicle collision. Front engine compartment absorbs most of the damage before it telegraphs into the passenger compartment.
