All the London railway stations :
Farringdon station is on ThamesLink, and the new Accessible Elizabeth line.
I revisited Farringdon station on 17th March 2023.
Elizabeth line trains run every five minutes, towards Abbey Wood or Shenfield, both via Whitechapel; or towards Heathrow, via Paddington. This is a very fast route to cross London.

It is important to understand that there are two separate stations which are opposite of each other at ground level. A short road crossing, although there is no traffic, or maybe a little. There are lifts in this station to the platforms.
The circle line, or metropolitan line trains at Farringdon are confusing, and you need to get on the correct train. Edgeware road is a good station to travel to if heading in the wrong direction to swap directions easily.
