This document describes the Halves and Quadrants (as defined in Mornington Nomic Rule 1.17.2) which the London Underground stations lie in.

The compass point-based information was derived by taking a printed copy of Kevan's GIF map and drawing two pencil lines on it through the Meridian of Tottenham Court Road: one East-West, and another North-South. All rail lines on the map were treated as valid.

Those stations which fell on or very near to one of these drawn lines are on a compass quadrant boundary.

Rather than enumerate every single station on the map with its quadrant, I've given the stations nearest to the quadrant boundaries on each line.

As an aide memoire, the Quadrant numbers correspond to the following geographical areas:

Quadrant	Region
0	on or within the Circle Line
1	North East
2	South East
3	South West
4	North West

The Halves are defined as follows:

Half	Quadrant Contained
North	1, 4
South	2, 3
East	1, 2
West	3, 4

The following table gives the stations in each Quadrant nearest to a Quadrant boundary. Stations in italics are actually on the Quadrant boundary. The stations are ordered along the boundary itself, and the Quadrant bounded onto is also given.

Note that the Half boundaries continue into Quadrant Zero - as such they follow the old Quadrant boundaries as defined prior to Proposal 475 (Year 2, Week 17). Stations in Quadrant Zero but which form a Half Boundary are in green.

The way to use this table is to look out for passing through a listed station: if your Move does pass through one of these, then you may be crossing a Quadrant boundary (it varies - Aldgate East is only a boundary station on the Hammersmith & City line for instance). If you passed through or Move to an italicised station then you have definitively crossed a Quadrant boundary.

Quadrant Zero Stations do not, inevitably, follow exactly this pattern. All Stations on the edge of Quadrant Zero are defined (being all Stations on the Circle). Italicised Stations are those which have a line passing through them which leaves the Circle - this may include Stations which do not exactly form the Quadrant Zero boundary itself eg Warren Street.
