Adapter pins for joining Lionel O gauge tubular track to O27 gauge tubular track. This pin can also be used to modify a FasTrack to Tubular adapter to accept O27.
Please note that unless using conductive filament, one may need to ensure electrical continuity between the two track pieces by other means (e.g. lockons or soldered wires).
I have included 2 .stl files for a spacers (angled and flat) to raise the O27 tubular track up to O gauge tubular track height.
The author marked this model as their own original creation.
