Bank, Central line, Northern line, DLR Waterloo & City. [Lifts to DLR and Northern are both now accessible], improved since Cannon street station opened in February 2023.
Barking, District line, Hammersmith & City, C2C to Fenchurch Street.
Underground lines are Fully Accessible, I tend to avoid Barking. Ramps onto c2c, and lots of confusing platforms.
