Two of these are true. One we made up. Tap the lie.

1. 1

   The London Underground's first line, the Metropolitan Railway, opened in 1863 using electric trains.

2. 2

   Only 45% of the London Underground network is actually underground.

3. 3

   The earliest written mention of London is a letter reading 'Londinio Mogontio', meaning 'In London, to Mogontius'.
