text: It's strange. :) Further to the northeast, there are twin lines again, from Lough Shore Road to the Hospital (it's easy to spot the lines over the water and you can then spot the towers) and then they seem to go underground to the substation. 
  
  Twin or triple lines happen from time to time - see the low voltage lines radiating from the substation. I imagine it's easier to get land agreements and planning permission where there are already existing lines.
  
  I wonder if what is actually present is two 110000-volt and one 33000-volt lines.
