Indeed it´s very hard to invent a "futuristic train".
* With regards to their drive, IMO the future belongs to electric drive, fed by a high-voltage catenary system. Only by using high voltage, e.g. 25kV, the needed power supply would be possible, but not with a low voltage system. By the same reason, DC systems (hence "third rail") aren´t "futuristic" either.
Using a catenary system is advantageous over any system which generates electric power "on-board":
- engines may be lighter without all the needed gadgets to produce electric power on-board,
- production of electric power by central power plants is more effective and environmentally favourable.
* Computerized control for trains is already in existence and one may argue that it´d be more widespread in the future. However, this is a feature which cannot be modelled sensibly in TTD.
* With regards to design, some of the existing high-speed trains do already have a quite "futuristic look". O/c, our reception is time-dependent, so this may be a questionable argument. Nevertheless, it doesn´t make the task any easier.
* Although the wheel/rail combination has been quite successful for the last 100 years, and e.g. the French TGV system suggests to be equally successful for the next decades, some very different systems could gain more interest in the future:
One of them is
magnetic levitation. Although this isn´t really a new concept, there are quite a few realised projects. One of the technically most advanced concepts is the German TransRapid system which, nevertheless, has been only realised for one single commercial line in Shanghai/China, except from its test-bed in Germany.
The most disadvantageous features of magnetic levitation are the high building cost of the track (in the TransRapid system it contains the linear motor), the high amount of (electrical) energy needed for the envisaged high travel speeds, and the incompatibility with the existing railway system.
Nevertheless, in TTD this concept (magnetic levitation) is already available, so developing any further "futuristic trains" beyond this seems to be quite hard, at least for the majority of set designers.
