the network. The Victoria line - also Metronet new stock - is a self
contained entity but the surface lines are not without connections to
all parts of national rail lines amongst others. Theres a whole host of
issues to be resolved.

The Metropolitan line, is connected to national Surface lines at
Harrow on the Hill, tt's connected to the Circle and H&C at Baker
Street. The Circle is connected to the District. The District is
connected to NR at several points, and is connected to the ELL between
Whitechapel and Aldgate East, and Whitechapel and Shadwell. The
District is connected to the Picaddilly at Acton Town/Ealing Common,
and the Metropolitin is connected at at Rayners Lane.

The Picaddilly is connected to the Central via a link between Ruislip
and Ickenham, it's connected to the the Northern at Kings Cross, and
the Victoria at Finsbury Park.

The Bakerloo and Jubillee are connected at Baker Street, The Bakerloo
is connected to the main line to Watford Junction, and the Jubille
line is connected to the Metropolitan line

Basically you can, assuming you override the signals and points, get a
train from anywhere on the underground network to anywhere else, and
escape on many northern facing tracks (although powering them would be
intereresting, and you'd need careful route planning to avoid any
problem curves)

The exception is the Waterloo and City, which is entirely self-
contained.
