7854 - 8 Straight Electric Rails Grey 12V
The grey era came with a great number of track options and accessories. Most were released in 1980, including this set 7854.
This set contains 8 straight conducting rails, which when added to 7850 provide 8 sections of straight track for 12V trains. This set was available from 1980 all the way to the end of 1990. The set came in two variations, first with power connector holes (for connecting to the 7864 transformer power output), later without said holes.
