Rolling Stock Maintenance: A major cost factor for Rail Operators

Maintenance accounts for approx. 30% of the lifecycle costs of a high-speed train,

making it the largest rolling stock operating cost factor besides energy

Comments Life Cycle Costs – High-speed fleet

In percent

Depreciation

 Besides energy and depreciation,

maintenance is the largest cost factor of a high speed train

 Over the lifecycle of a high-speed train, maintenance costs exceed

depreciation

 Approx. 60% of maintenance costs are personnel cost and 40% for

material / spare parts

 For a fleet in service, maintenance cost is the major cost position

subject to optimization as

depreciation and energy stay constant during the fleet’s lifecycle 23% 30% 30% 11% 7% 100% High-speed Energy Maintenance

Lean Workshop Transformation – Objective

Lean Workshop Transformation eliminates the root causes creating inefficiencies in the

workshops by creating a higher level of industrialization of the workshop

A B C

Objective of Lean Workshop Transformation Typical issues creating inefficiencies in a rolling

stock maintenance workshop (examples) Maintenance tasks are not standardized

- Inadequate checklists or work instructions - Lack of standards for tools and locations - Missing standard times for tasks

Workshop organization not performance driven

- Lack of performance management

- Supervisors lack information about job status - No sharing of best practices

Insufficient planning and preparation

- Repairs are given the highest priority and interrupt scheduled work

- Scheduled maintenance tasks are started before all parts and equipments are ready

Infrastructure constraints

- Tracks are not equipped in a standard way - Teams have to wait for a shared equipment to

become available

Spare parts logistics

- Long lead times for spare parts - Repairables logistics not optimized

Industrialization of the workshop

- More standards - Higher efficiency

C

(14)

Lean Workshop Transformation – Foundations

Industrialization is achieved by applying Lean and Six Sigma concepts in 3 key areas:

Work standardization, Workplace organization and Shopfloor management

A B C

C

Lean Manufacturing

 Lean system: delivery of products and services matched to customer needs

 Lean concepts: eliminating waste, i. e. anything not adding value to the product or the

customer, and improving process flow

 Lean approach: a total organizational and cultural transformation

Six Sigma

 Six sigma system: reduce variation and defects to improve quality

 Six sigma concepts: reduce process variation to eliminate defects, while ensuring the organization is focused on the voice of the customer to

differentiate products and services  Six sigma approach: measure

defects, analyze the root cause, systematically improve the system and ensure sustainment of the gain Lean Workshop Transformation 3 focus areas:  Work standardization  Workplace organization  Shopfloor management

(15)

Lean Workshop Transformation – Overview

Our experience shows that these 3 areas are key pillars to drive Lean Workshop

Transformation

 “A place for everything and everything at its place”

 Visual management standards

 Use of shadow boards to ensure tooling is complete

 Sorting and systematic storing of parts/tools  Creation of additional

Lean Workshop Transformation – Shopfloor management

Efficient shopfloor management relies on effective communication by maintenance

managers and team leaders

Principles of effective communication Rules for visual displays

 Communication should be structured, disciplined and frequent

 All meetings held on the shop floor via information centers/boards and or team rooms

 One-on-one communication regarding results of a process or other audit take place at the point of cause (POC) or location of the audit with the appropriate employees

 In effective meetings only relevant information/issues based on actions / feedback and accurate data are discussed

 All information and data are kept on simple, visual displays (e. g. boards), which are – Completed in a timely manner

– Updated by hand whenever possible – Reviewed regularly by key personnel  Characteristics of simple, user-friendly

visual controls:

– Current status communicated at a glance – Prompt “go and see” activity

– Initiate containment, countermeasure and support activity

Practice

PM is carried out using comprehensive checklists as a reference – standard times are defined for the whole checklist

For key tasks, standard worksheets show the optimal way to perform the task. All workers are trained to the optimal method For main fault categories, curative interventions (inspection, repair) are standardized (use of fault trees,…)

Clear separation of team spaces and workplace

Workplace is always clean and orderly, tools are kept at their designated places, materials and parts are stored away

Visual management standards (floor and installation markings, tags,…) are defined and implemented everywhere

5S checklist, KPI and audit process exist to sustain workplace organization standards

Team meetings, lead by supervisors, take place at least once per shift on the shopfloor to perform resources and work planning Visual displays, updated daily, with work and resource planning,

SQACM1KPIs and PDCA action plan efficiently support meetings

All unsolvable issues at one level are escalated, using the correct escalation process, and are resolved in due time
