The Interrail is a train system in Fusion City, designed to take you virtually anywhere within the boundaries of the Perimeter Wall. That might be a slight exaggeration, but it'll get you close and it'll get you there fast. The Interrail is one of the fastest methods of transport within the city, outpacing even private hovers most of the time.
It does this with great speed, high reliability and frequent departures. The Interrail moves millions of people every day and night throughout the neon-lit city.
Each train is a double-headed construction with six cars to carry people in. Each car is capable of transporting 110 people comfortably, however disembarkation can become a bit of a stressful affair.
The trains are capable of traveling at over 440 Km/h at peak velocity, however it must slow down for some of the sharper turns along the rail. It also takes a while for the train to accelerate to top speed, not because of performance, but because of comfort. Every passenger is required to be seated, and belted, before the train leaves or you risk injury by being tossed around inside. With that speed it can get you whereever you need inside the city within two hours.
