I want to know the answer to the following question:
What line used the overhead wire system first Victoria to Crystal Palace or Peckham Rye to West Noorwood?
All the background I'm provided with is that "In the UK, the London, Brighton and South Coast Railway pioneered overhead electrification of its suburban lines in London, London Bridge to Victoria being opened to traffic on 1 December 1909.". Is that enough to answer the question?
Answer: no
