scope:

This standard applies to revised inspection and maintenance regimes for plain line track system assessed using the Reliability Centred Maintenance process (NR/L2/MTC/10662) of the following assets on running lines:

a) plain line flat bottom Continuously Welded Rail (CWR) - Regardless of PLPR status;

b) line speed 125mph or less; and

c) axles loads 25.5tonnes or less.

The scope of this standard excludes:

d) switches & crossings;

e) bull head rail;

f) adjustment switches;

g) jointed track;

h) buffer stops;

i) slab track;

j) long timber bridges;

k) complex or non-standard layouts;

l) off track features (fences / none track drainage / vegetation); and

m) non-running lines

NOTE: These excluded assetsl continue to be inspected and maintained as mandated in modules NR/L2/TRK/001 unless bespoke Risk Based Maintenance regimes are agreed and implemented as per NR/L2/MTC/10662

The scope of this standard excludes the following inspections:

n) Track Maintenance Engineer inspections

o) Super Red' inspections

p) 'Very Poor' eighth inspections

Purpose

This standard defines alternative inspection and maintenance regimes to those mandated in NR/L2/TRK/001 based on the application of Risk Based Maintenance (RBM). This simplifies the implementation of Risk Based Maintenance regimes detailed in NR/L2/MTC/10662/05.
