Comments from Submitter:
The pictures on the front and back of the box clearly show the 3241b Conducting Rail Curved without Cable Connection Holes.
From 1980 to 1983 the pictures both on the Lego Catalogue and the Train Catalogue show the 3241b Conducting Rail Curved without Cable Connection Holes too, so it should be included in the first production runs of the set.
Since 1984 the pictures on the Lego Catalogue show the 3241 Conducting Rail Curved with Cable Connection Holes.
Here above some pictures: the first is from the 1980 Train Catalogue, the second
is from the 1981 Train Catalogue, the third is from the 1982 Train Catalogue,
the fourth is from the 1983 Train Catalogue.
