they managed to produce the victoria line pretty cheaply. I don't see
why its such a struggle to produce another line cheaply.

Too much on the cheap. Kings Cross was left as a fire trap. Several
stations, notably Victoria, Oxford Circus and Kings Cross were too small for
the number of passengers using them, and are having to be expensively
enlarged. Brixton needs three platforms to turn back the whole service, but
only has two. While there is good cross-platform interchange at Stockwell,
Oxford Circus, Euston, Highbury & Islington and Finsbury Park, interchange
at other stations, particularly Vauxhall and Green Park is as bad as it is
possible to make it.
