It's very dependent on obviously the nature of the power source used to power the trains, how loaded the trains are, how fast they go (so route dependent etc).

It's very dependent on obviously the nature of the power source used to power the trains, how loaded the trains are, how fast they go (so route dependent etc). The BBC can't really be trusted to get complex topics right. They're just quoting some activist organisation there. Note that the figure is "per passenger" but that turns to assume fully loaded vehicles. The airline industry is much better at keeping seats full than train operators are. A nearly empty train will be much worse for the environment than a full plane. As for trucker strikes, yes, but that happened mostly because they were allowed to blockade refineries. In the UK at least laws have changed since and there are mitigations in place. If you look at the rule changes around unions coming up there, they're motivated by rail strikes because those are a common occurrence whereas strikes taking it out roads are not.
