This 120 year old footage from PhoenixCinemaTrust shows the Switchback at Alexandra Palace, London. It’s some of the best footage we have seen of a Switchback Railway.
“First saw this at Hornsey Historical Society AGM. It has been around for ages, but previously not identified as Alexandra Park. The Tudor style building in the background is the giveaway. It is the Blandford Hall/Banqueting Hall/Tudor Hall which predated the Palace and burnt down (I think) in 1970.” – Find some further discussion here.
