scope:

This Standard applies to the spatial aspects of station planning in the following areas:

Public areas within stations

Operational staff accommodation

For normal operation and evacuation

This Standard addresses and supports spatial planning issues of:

Passenger flow

Ticket hall

Access and Interchange facilities

Secondary income facilities

Operational staff accommodation

Station control rooms

Ticket issuing facilities

Platforms

Evacuation

Public facilities

insofar as they relate to Station planning.

This Standard shall be used to identify the station 'footprint' and to ensure that station proposals meet the requirements of HMRI Railway Safety Principles and Guidance (Part 2 section B Guidance on stations).

Purpose 

The purpose of this standard is to define the space requirements for public areas and staff accommodation in stations.

This standard applies to: 

New stations 

New assets within existing stations. 

Altered assets within existing stations.

When work is proposed that:

- does not involve alterations to the primary structure of the station, and;

- is defined as clause 1.2 b) or c) (new or altered assets within existing stations) and;

- where it is impossible to comply with the headroom and platform width requirements of this Standard without major re-building/alteration to the existing structure of the station, then the following conditions apply:

• Risks that are introduced by the proposal shall be identified, assessed and evidenced ALARP by the proposer; 

• Proposals shall be demonstrably optimal in relation to the compliant state for new stations;

• Proposals shall always comply with the minimum dimensions set out in sections 3.5.2, 3.10.5.3, 3.11.2.4, 3.11.7.3 of this Standard.

The reason for these sections is to recognise that the structure of an existing station may not be able to accommodate some of the constraints of this standard in terms of linear dimensions, available floor area or volume. If this is the case the onus is on the Supplier (as proposer) or other proposer to identify all risks associated with their proposal and to prove and evidence that these are ALARP in accordance with other relevant Category 1 Standards.

The Supplier (as proposer) or other proposer must also be able to demonstrate that their proposal is the best that can be achieved under the circumstances, offering optimal compliance to the standard. This will typically mean an analysis of available options. If these conditions are satisfied and if the minimum dimensions listed in the relevant sections of this Standard can also be met then a concession application is not required.

All dimensional requirements for room areas, passageways, stairs, and run-offs are not affected by this note.
