[OSRM-talk] Use OSRM on rivers, railways, power lines

[Daniel Patterson]

Yes, connectivity will be a problem in that example.  If you make the lines
`is_startpoint=false` and they're not connected to something else, then you
won't be able to route over them.

You will need to do some pre-processing here - create artificial nodes at
the points where the substation boundaries cross the lines and connect both
ways to those artificial nodes.
