4 lane digital track

so anyway, heres the thing.... i've got a 4 lane track and want to make two of the lanes into digital...

from reading the forums i gather that the changeover curves don't connect the power between lanes, so these will work with a standard sport power base allowing me to put them into the layout and still run it as a standard four lane when i want to... is this true?

all i need to do is change the power base in the layout depending on whether i want to run 4 lane standard or 2 lane digital?



how about a four lane digital!!!!! that would be crazy... anyone got any ideas about this
