That's exactly what I need, thank you

It doesn't matter indeed.
But it may be an issue that power lines aren't actually connected to
substation perimeter ?

Like this one : https://www.openstreetmap.org/way/100500802
The outside edge of the substation is the fence surrounding it and power
lines goes above it without connection.

Should I preprocess my data to make it more accessible to osrm or there's
other way ?
