This article lists the major features of London Underground lines,
culled from various sources. For each line the following are given:
- an indication of which parts are in tunnel;
- details of single and multiple tracks (lines are double track unless
  stated), and usage of other lines' tracks;
- details of connections to other lines;
- locations and access details of train maintainance depots.

Any corrections to this information would be appreciated.

The notations (E) and (I) mean "exclusive" and "inclusive" respectively.
The notation [[...]] means that this connection is not shown in all my
source material (this applies to the line from Finchley Road to Wembley
Park, and I would appreciate confirmation from someone who has actually
gone and looked *recently*).
For depots, the term "both ends" means that the depot can be entered
from either end, in the direction leading to the other end (for example,
a train travelling north from Hainault (Central line) could run through
Hainault Depot and then continue northwards through Grange Hill without
stopping or reversing).
