A British Rail Class 455 train. This train served as a workhouse for South London's commuter network, but is slated for retirement soon. Pay some appreciation to these historic powerhouses!

Trains are the single most effective way to transport things over land, whether it's cargo or passengers. Even in countries with a notoriously bad passenger rail network, like the US, railways still rule when it comes to cargo, with the US having a massive, incredibly expansive cargo network.

Trains are crucial to a modern world, no matter how you cut it!
