Organization: NR
Publication Date: 7 March 2020
Status: active
Page Count: 20
scope:

The modules within this standard describe the requirements for:

a) boundary measure classifications;

b) boundary measure specifications;

c) a register of assets;

d) inspection of boundary measures protecting Network Rail's operational infrastructure, depots and adjacent railway facilities;

e) inspection of boundary measures protecting Network Rail's disused and closed lines and other non-operational land;

f) inspection of third party owned boundary measures which are used to control unauthorised access to the railway;

g) maintaining the boundary;

h) degradation and renewal;

i) risk assessment;

j) response and rectification time scales;

k) investigation of incidents; and

l) prioritisation of works. 

Not included within this manual are:

a) inspections of security measures that do not form part ofthe boundary;

b) inspections of retaining walls (see NR/L3/CIV/006 part5A); and

c) inspections for vehicle containment (seeNR/L3/CIV/00012).

 

Purpose

 

The management of the boundary measure is a process usingrisk assessment that contributes to the safe performance of the railwayinfrastructure and our duty of care to the public. Loss of an effectiveboundary measure affects the safety and performance of the railway.

Management is required to assess that:

a) the boundary measure adequately delineates Network Rail property from that of a third party or adjacent railway facility;

b) the boundary measure provides a continuous barrier thatis adequate to deter threats of trespass and livestock in cursion onto Network Rail property from the

adjacent land where they are reasonably foreseeable; and

c) the construction of the barrier is of sufficient designin relation to the threat that is expected from the adjacent land use. 

The bow-tie threats to continuous effective boundary measures are:

a) deliberate damage from acts of trespass and vandalism;

b) non-deliberate damage from livestock which includes most domesticated animals kept on land (commonly, horse, cattle, sheep, pig andgoat);

c) non-deliberate damage from road vehicles or fallenobjects including trees;

d) non-malicious acts by railway personnel;

e) unchecked asset degradation leading to failure of components;

f) inappropriate boundary measure specification, dimensionor components that do not adequately deter trespass or incursion;

g) change in land use and railway characteristics that will increase the likelihood or consequence of an incident; and

h) effectiveness of boundary measure reduced by external occurrence such as change in ground level next to the boundary due to landslip,snow loading,

wind-loading, waterlogging and washout of footings.
