Is there a kind of signal for double tracks

[BJ3226]

I am just looking for a kind of color light signal for double tracks, which can serve to each track at the same time.

Thanks very much!

I am not aware of any, nor of any method such a signal could work. Double tracks are simply two individual splines of track set to bend around a central, controlling spline point. However, there may be someone smarter than me with opposing information.
