Stock on sub-surface lines is identified by a letter (such as A Stock, used on the Metropolitan Line), while tube stock is identified by the year in which it was designed (for example, 1996 Stock, used on the Jubilee Line).
Lines of both types usually emerge onto the surface outside the central area, except being the Victoria Line, which is in tunnel except for its depot, and the very short Waterloo and City Line which has no non-central part and no surface section.
The lack of lines in south London is sometimes attributed to the geology of that area, the region being almost one large aquifer; additionally, it is impossible for cut and cover lines to go under the River Thames.

The Central London Railway was formed in 1891 to build a tube railway along the east-west axis of London, connecting the western suburbs to the City.
The through lines joined on to the east and west sides of the loop, with the loop platform in between; since the loop ran anticlockwise, right-hand running was in use from there to a flyover at Wood Lane Junction where the link met the EandSB.
The line runs in tube from west of Leyton to east of White City; at Stratford the lines use the main line station on viaduct and at Mile End it rises to the level of the District Line cut-and-cover station to offer cross-platform interchange.

 Institute for Healthcare Improvement: Central Line Bundle Compliance
The percentage of intensive care unit (ICU) patients with central lines for whom all five elements of the Central Line Bundle are documented on the daily goals sheet and/or central line insertion checklist or patient's medical record.
For example, if there are 7 patients with central lines, and 6 have all five bundle elements completed then there is 86 percent (6 divided by 7) compliance with the Central Line Bundle.
Incorporating the five elements of the Central Line Bundle into a central line insertion checklist and a daily goals sheet, and reviewing lines daily during multidisciplinary rounds, allows for easy review of bundle compliance.

Central means that the line is in a large enough vein, in the central circulation, that it’s safe to deliver drugs that might not be safe if given through smaller peripheral ones.
Once the line is in what ought to be the right position, which varies with the size of the patient, it’s sutured to the skin with a little tabbed flag thing.
Placing the line over the wire is simple enough if the line is a single lumen introducer, but if a multilumen line is being used, it pays to remember that the line is going to have to pass through the distal opening — the one at the tip-end of the catheter.
