### Another source of this information is the series of Trackmaps books
covering the entire British isles, http://www.trackmaps.co.uk/ Book 5
Southern and London Underground being the one of interest, giving track
layouts, flyovers/unders, distances in km from somewhere in deepest Essex,
called Ongar ( where all underground distances are based from.) These books
are very good, so much so, that even NOTwork Rail buy them by the barrow
load. These books are available from the Ian Allan bookshop.

Hi

Boarding a train at Pimlico going north the southbound trains are on the
right if i face the front of the train. Somewhere between Pimlico and
Kings Cross they change to being on the left. Where do the lines go over
and under each other and is there a tube map published that would give
information like this.

Thanks

Clyde
