<Games Workshop> Okay maybe we can't fit cannon on every part of the track, but you know what? I was reading a book the other day and it mentioned 'railway spikes' used during construction. If real-life railways sometimes had spikes, then Warhammer railways can have lots more and bigger spikes, right? It'll be self-defending against monsters and bandits, but it'll also serve as a big obstacle to anyone wanting to cross the Spikeway, like super barbed wire, so we have another reason for internal conflict and technological stagnation as people object to the Spikeways.
<Several hundred people> THAT'S NOT WHAT A RAILWAY SPIKE IS!
<Games Workshop> Too late, we already filed for the trademark on "Imperial Spikeways".
