scope:

This Guidance should be used by developers, local authorities, consultants, other third party promoters and Transport for London (TfL) and London Underground (LU) staff.

It covers the planning processes that promoters should be aware of during the early stages of new project development.

It draws attention to key requirements of LU standards relevant to the early stages of design.

It refers to key design considerations that are not always evident or may be overlooked.

It relates to new lines or extensions to existing lines where the operational concept is similar to that used by LU. It does not refer to new lines whose operational concept is significant ly different (e.g. Crossrail).

Its primary focus is with land and space requirements and design options having a significant impact on cost.

The guidance does not offer solutions. However, where design compromises are evident, it may provide a general „steer‟. This is not a substitute for ROGS or other legislation and actual requirements will depend on many factors including sponsor‟s scope, legal constraints, commercial and environmental matters.

Purpose

The guidance in this document describes the main factors that are relevant to the planning and design of new London Underground lines and extensions to existing London Underground lines at project inception.
