It's the best-known means of transport in the city of Cryptonnoria, where you'll find the wealthy classes, corporatists, artists and quite a few stars.

With the city stretching for thousands of kilometres, this is the most efficient way of reaching a distant destination in just a few minutes.

For social events, concerts, meetings and business gatherings, it has become the main means of travel for the majority of the population.

One ticket is paid for with the cryto Looper, which has risen sharply in value over the last year, and trains may be fully booked at peak times.

A pass in the form of an NFT has been introduced, with a system of classes depending on the carriages, and luxury services are granted to premium passes, such as sumptuous dishes, private dances and other entertainment.
