These days it's fare dilation instead

Did you know that British Rail patented an interplanetary passenger vehicle?

The craft was to be powered by nuclear fusion, using laser beams to produce pulses of nuclear energy in a generator in the centre of the craft, at a rate of over 1000 Hz to prevent resonance, which could damage the vehicle. The pulses of energy would then have been transferred out of a nozzle into a series of radial electrodes running along the underside of the craft, which would have converted the energy into electricity that would then pass into a ring of powerful electromagnets (the patent describes using superconductors if possible). These magnets would accelerate subatomic particles emitted by the fusion reaction, providing lift and thrust.
