Marklin 24649 - C Track Crossing 48.6 degrees
C-Track Crossing, 103.3 mm / 4-1/16 inches. Crossing angle of 48.6°.
For double crossovers or intersecting parallel routes.
Charlie's Tip: A short brown wire comes with the crossing. Turn the crossing upside down. Connect this wire to the two tabs marked "O" of the two crossing tracks. In other words, find two of the tabs marked "O" that are closest together, and push the brown wire over those two tabs.
The center crossing rails are not connected to each other. This is done so that in analog operation, crossing seperate circuits stay seperated. In applications where this is not desired, you can run a wire between two tabs marked "B" on the crossing tracks.
