1. Purpose
This document exists to support the requirements of rolling stock assets as set out in the
Franchise Agreement.
1.1.
DLRL Vehicle Maintenance Minimum Requirements (VMMR) outline the requirements
for a Maintenance Plan. They set out what maintenance needs to be performed but
not how the maintenance is to be performed, unless an established good practice has
already been established. The intervals at which maintenance must be completed are
not specified either, except that some maximum limits are given and there is a
requirement that the interval should be set so as to ensure continued compliance to
the essential requirements. Further, as explained in MR-700, VMMR’s are neither
exhaustive nor prescriptive: suppliers meeting these documents are not guaranteed
to deliver system safety or performance; suppliers may apply to vary them.
1.2.
DLRL VMMR’s focus on
output measures (not input ones), however some
essential
requirements are specified, such as:
• critical limits / backstop on how often certain activities must be carried out e.g.
bogies to be overhauled within x thousand miles, but not precisely when; and
not how to group different maintenance activities together efficiently
• critical processes of how to carry out particular activities e.g. where experience
has derived a best practice approach, which DLRL passes on as part of its
knowledge management role, in order to mitigate known DLRL reputational
risks.
1.3.
DLRL VMMR’s provide a baseline:
• against which DLRL audits of work done can be carried out to assess franchise
compliance;
• such that related documents can be assessed for compliance (e.g. suppliers’
maintenance recommendations); and
• which can be enhanced over time e.g. best practice emerges from
investigations.

2. Application
This VMMR applies to DLRL’s Franchisee through the Maintenance Standard for Rolling
Stock, MR700.
MR700 sets out management requirements on the franchisee, and mandates
Vehicle Maintenance Minimum Requirements (VMMR) which set out the requirements for
the Maintenance Plan, specifying what minimum requirements are to be maintained and
giving limits on by when critical activities must be performed.
Each VMMR section may call up
Maintenance Specifications (MS) which are discrete self-
contained documents for use by overhaul contractors, consistent with best practice (i.e. for
traction motors, bogies, couplers, compressors and wheelsets). VMMR may also call up
Project Specifications (PS) which set out specifications to which the rolling stock is
modified/ refurbished / upgraded.

3. Scope
This Vehicle Maintenance Minimum Requirements document applies to DLR’s B90 / B92 /
B2000 light rail vehicles only for the purpose of this document it will reference B92 as all
vehicle types are comparable. It specifies what the minimum requirements are to be
maintained (mandating MS and referencing BT Manuals as required) and gives limits on by
when critical activities must be performed (e.g. gearbox overhaul must be carried out prior to
a certain number of vehicle km’s run, brake pads must be renewed such that minimum limits
are not exceeded in service).
Fundamentally, VMMR’s specify what is to be done, with some key limits on when. They do
not generally set out how maintenance is to be performed or grouped together logically into
exam block cards or whether regimes should be balanced or cumulative; nor yet the level of
granularity of maintenance by individual component (e.g. franchisees may find that condition
monitoring and life item approaches elicit best performance and most efficient life cycle
costs).
VMMR 92
•
Within the VMMR are a number of sections. Each section represents a system,
assembly or sub assembly of the vehicle, example Section 1 Shoegear, Section 12
Couplers.
•
The Sections are represented in the VMMR 92 via a star chart, specifying key limits at
which a maintenance activity is mandatory.
•
Other Maintenance activities within the star chart are indicated by
‘’As Required’’
giving the franchisee the scope to undertake the maintenance activities at the best
optional interval, documented evidence of the periodicity chosen will be required to
demonstrate the decision / justification.
Each VMMR:
•
Lists MS in a star chart, specifying the limits when each overhaul is to be undertaken;
•
In the absence of a MS, identifies the best documentation available – typically an
extract from the OEM maintenance manual, applied at the periodicity specified
therein;
•
Specifies requirements of where data is to go in the asset management system (i.e.
electronic records), even where work is undertaken according to a MS, since overhaul
providers may be supply chain partners who may not have access to the asset
management system , whereas the Franchisee who delivers the VMMR does. See
also Section 10 Records below.

4. Definitions and Abbreviations
All periodicities are in km. A tolerance exists on each exam of 900km (an average of 3 days
duty service), the tolerance is not cumulative and is applied to an exam but does not change
the original drop dead position of the next exam, i.e. if the 900km tolerance is used on a an
exam past the 13,500 km point the next exam is due in 13,500km minus the 900km overrun.
Please see
MR1000 and
MR700 for definitions and abbreviations.
