"When the Underground first opened in 1863, It relied on steam trains to pull its carriages - a system used by some parts of the network until the 1960sl Electricity was first used to power trains in 1890, and soon became the standard on our network."
A very happy new year to you! I sure hope you're having a good time so far and can't wait to see what's in store for use in 2020. It’s always a good idea to have an icebreaker, explore and go for a walking tour either in a group or solo. Passing by the Foundling museum in London was an eye opener and reminded me about how much hidden history is available in this amazing city!
