This invention relates in general to model railroads and
of each insulating section by a strengthening ‘and securing
stake plate having upwardly projecting ‘studs which are
bent over the ?anges of these rails.
A feature of the construction is the provision of a third
rail which is made of a conductive copper which is of a
color which blends with the ties and thus makes it rather
inconspicuous. The ties are made hollow and the third
rail is secured to alternate insulating ties by forming the
rails with securing tabs which may be alternately bent
underneath the hollow ties to secure them in place thereto.
The assembled track structure is both lightweight and
sturdy and may be assembled to similar track structures
by a ball tongue and groove construction which permits
interlocking of the insulating ties as well as alignment and
securing of the rail members and their electrical connec
tions for current't-ransmitting and grounding purposes.
Accordingly it is an object of this invention to provide
gitudinally extending, track supporting bridging members
'20 and 22 located at each side of the ties 18 and provid
ing a flat support for the rails 12 and 14, respectively.
The supporting structure 10 is reinforced by forming
the last two adjacent ties with a bridging web 23 which
interconnects the central portion thereof. In addition the
central pair of ties are provided with a bridging web 24
(FIG. 3) which is similar to the web 23. Each track sec
tion, therefore, has three bridging webs, the two end ties
on each end having the bridging web 23 and the center
two having the bridging web 24.

Each of the bridging webs 23 ‘and ‘24 are provided with
a pair of downwardly extending aligning or centering
bosses 26, 26 to permit centering of correspondingly di

Thus the invention provides a very inexpensive track
structure which has the advantage of being both durable
and sturdy and is also very easy to assemble to similar
sections of track. The track structure permits accurate
aligning of the track sections and maintenance of the 55
assembled trackway in its aligned interconnected rela

structures constructed in accordance with the invention
there is no likelihood of any current failure or track
separation. The track structure ideally simulates the 60
look of an actual full-scale railroad track.
