7850 - 8 Straight Rails Grey 4.5V

32 pieces

from 6 years

The grey era came with a great number of track options and accessories. Most were released in 1980, including this set 7850.


Set 7850 contains 8 sections of straight track, with each section being composed of 2 straight rails and 2 sleeper plates. These sections are suitable for push-along trains and 4.5V motors. If you want to use them for 12V trains, you also have to add a conducting rail 7854.

This set was available from 1980 all the way to the end of 1990.
