1988. Speed record in Germany with the
experimental train 401 (407 km/h) on the
high-speed line between Hannover and
Wurzburg.

1989. SNCF receives the TGV Atlantic trains,
the first TGVs with three-phase synchronous
motors.
1990. World speed record in France with the
TGV Atlantic 325 branch (515.3 km/h).

1993. First application in the world of the Alstom

2015. The Japan Research Institute of
Technology (RTRI) tests superconducting
cables in an aerial electrification system for a
direct current passenger line. It is verified
that with this type of cable considerable
energy savings can be obtained as well as
improvements in voltage stability. Until this
moment, no real tests had ever been carried
out on a line.

2015. The European research project
RFF MERLIN (Sustainable and intelligent
management of energy for smarter railway
systems in Europe: an integrated optimisation
approach) concludes, and can be considered
as the starting point for the development of
future projects and new systems for
intelligent management of electrical energy of
the railway. This project was developed
under the VII Framework Program for
Research of the EC.
