About Trains 9V

The 9 V system ran from 1991 to 2006 and is still a favourite with LEGO train fans. The rails have metal tops that carry the current from a speed regulator to a motor under the locomotive, so trains could run without batteries for as long as they stayed on the track. It started with 4558 Metroliner in 1991.

9V consists of 67 sets that ran from 1991 to 2006. As of today, 4558 Metroliner is the most valuable 9V set with an estimated new/factory sealed value of $1,989.
