<p>Continuity can be had by the lines sharing a node. In the same
way roads share a node to enable routing. <br>

<div>It is different from a line as a physical lines can hold
several of those circuits for a given distance (situations
where you have n x 3 cables in a 3-phases power network).<br>

<p><br>
</p>
<p>I would expect a line that has n*3 cables to be tagged cables=3;3
(for n=2, add more ;3 for more n). This would signify that the 3
phase circuits are separate. <br>

<p>Humm problem in identifying which of the 3 phases is connected to
which when the line splits off. <br>

<p>Who uses this route relation - as in a end use? Or is this a
'build it and they will come' thing? <br>

<div>The proposal didn't reach the requested consensus.</div>
<div>There are currently two options for power routing,
including route=power but until now we didn't manage to find
a single solution to be voted. Discussion is still open I
think.<br>

<div>It is really useful and verifiable : follow the connected
cables.</div>
<div>Some countries like France make open data available that
describe those relations.</div>

<pre>However I view them similar to roads .. there maybe a power line there .. but 'traffic' can be in both directions.
