scope:

This module describes the minimum requirements for the planning and safe operation of On Track Plant (OTP) trailers and wheeled attachments.

This module applies to all organisations that are involved with any of the following:

a) planning or supply of any trailer or attachment;

b) carrying out or controlling of operations involving any trailer or attachment; and

c) maintenance of trailers or attachments used on Network Rail managed infrastructure and Network Rail projects.

This module applies to:

a) trailers and attachments with more than two rail wheels, towed or propelled by on-track plant (OTP);

b) OTP that is towed as a trailer; and

c) failed OTP that is being recovered from Network Rail managed infrastructure.

It does not apply to trailers with braking equipment to UIC (International Union of Railways) specifications.

Guidance is given on the appropriate loading and unloading sequences of trailers and the securing of all loads.

See the index of NR/L2/RMVP/0200 for information on which:

a) specific roles this module applies to; and

b) modules that also apply to those roles.

Purpose

The implementation of this module contributes to mitigating the following risks:

a) compliance with legislation (LOLER, PUWER, HASAW);

b) runaway/failure to stop on demand, e.g. OTP running away on a gradient;

c) poor site or weather conditions;

d) damage to assets, e.g. RRV or its load hitting a passing train during ALO operation;

e) collision, e.g. collision between a RRV and an OTM; staff injuries, e.g. Operator being trapped between machine and infrastructure;

f) operating error, operational error or equipment misuse;

g) lack of RIDDOR or close call reporting; and

h) lack of continuous improvement, such as, mitigating factors from incidents not being introduced to machine/operating procedures.
