Victoria line
At Euston, northbound Victoria and Northern line (Bank branch) trains run along platforms next to each other, although they are travelling in opposite directions. "Same-direction" cross-platform interchanges are available at Stockwell (with the Northern line), Oxford Circus (with the Bakerloo line), Highbury & Islington (with First Capital Connect, originally the Northern City Line) and at Finsbury Park (with the Piccadilly line).
