1.
A useful umbrella term describing the Circle, Hammersmith & City and Metropolitan lines' shared route between Baker Street and Aldgate.

On London Underground maps these lines are individually colour-coded yellow, pink and magenta. When viewed side-by-side the lines resemble Neapolitan ice cream, albeit with the Metropolitan line's dark magenta replacing Neapolitan ice cream's chocolate brown.
Example 1:
"How do I get from Liverpool Street to Farringdon?"
"Any of the Neapolitan lines will do"

Example 2:
"What lines pass through Baker Street?"
"The Bakerloo, Jubilee and Neapolitan lines"
