ECM certificates of TRW

 

Self-declared as ECM on 29/11/2010 – valid until 31/05/2012

 

Certified as ECM – certificate FR 34 2012 0001 – 23/05/2012 Bureau Veritas• Based on the protocol agreement MoU• Valid until 31/05/2015

 

Objective: convert the certificate to EU 445/2011 in May 2014

Wagons of ECM TRW

 

TRW became ECM:• Before 02/11/2012: the wagons of IFB overhauled according VPI - around

600 wagons• As from 02/11/2012: all the wagons of the keepers Xpedys and IFB

 

Wagon fleet (situation December 2013): 7363 wagons

IFB 2394 wagons (intermodal)

Xpedys 4969 wagons (conventional)

 

Evolution of the total fleet:

January 2013 8857 wagons

December 2013 7363 wagons

Decrease of - 1494 wagons

Maintenance Reference Files MRF (I)

 

MRF = the complete set of maintenance rules and specifications to apply on the wagons (and on the wheel sets) during each maintenance intervention

Maintenance interventions:

• Preventive maintenance Major Overhaul MOSimplified Overhaul SO

• Corrective maintenanceIncidental Repair IROthers: VSP – PMB – etc.

Maintenance Reference Files MRF (II)

MRF applied by ECM TRW:

• Starting with three references

SNCB regulations

VPI guidelines

SNCF regulations: 80 wagons with disc brakes• Objective: to keep only VPI

28/04/2014

Robert Bauwens 8

Why switching from the SNCB to VPI

 

1. Workshop capacity for MO and SO

2. Flexibility for IR beyond the GCU repairs

3. Prices

4. VPI as future European Maintenance Standard ?

Robert Bauwens 9

When switching from SNCB to VPI (I)

1. Wagons

Progressive during preventive maintenance MO and SO

SNCB 90 % 71 % 58 % 7 %

VPI 10 % 29 % 42 % 93 %

SNCF = 0 %

#MO +SO 2011 2012 2013 2014

SNCB 1494 1092 729 ± 100

VPI 167 443 526 ± 1300

SNCF 0 7 0 0

TOTAL 1661 1542 1255 ± 1400

Robert Bauwens 10

When switching from SNCB to VPI (II)

IR beyond the GCU repairs: two regimes at the same time according the MRF of the last overhaul of the wagon (IR in the scope of GCU according the MRF applied by the RU which approved the workshop as its auxiliary)

As from 01/01/2014• IR beyond the GCU repairs: according VPI

When switching from SNCB to VPI (III)

2. Wheel sets

During overhaul IS2 / IS3 Wheel sets according SNCB and wheel sets according

VPI Both authorized under the same wagon (but to avoid)

 

3. Other components (pneumatic components, buffers, …) No switch from SNCB to VPI Overhaul according instructions approved by the

component suppliers Overhaul in specialized workshops approved by the

component suppliers

How applying VPI (I)

VPI• Are guidelines• Is not always suited for Belgian wagons

SNCB • Is a regulation• Is tailor made for Belgian wagons

ECM TRW regulations• The basis is VPI• A layer added with proper TRW regulations• Layer can be in plus or minus• New situation with VPI and ECM TRW regulations must be at least as

safe as the former situation with SNCB regulations Risk Analysis

Robert Bauwens 13

How applying VPI (II)

Exemples

1. VPI not so strict as SNCB regulation

a. Overhaul of particular pneumatic components

SNCB10 yearsReplace if 10 years exceeded during next OH of wagon

VPI15 yearsReplace if 15 years exceeded during OH of wagon

2. VPI is more severe than SNCB

a. Corrosion on wheel set axles and monobloc wheels

b. Play between wheel set axle and brake connector

c. Uerdinger buffers

Robert Bauwens 14

How applying VPI (III)

3. TRW regulation not so strict as VPI but equal to SNCB regulations

a. No UT after reprofiling with underfloorlathe b. No brake test after brake block replacement in the field

4. Nothing in VPI proper TRW instructions

a. Autocontinu AC3Db. VTA weighing valves

ECM certification of workshops (I) 

• SNCB workshops• SNCB workshops know the wagons• ECM knows the workshops• Computerized data exchange• Until 31/12/2013: according SNCB regulations,

since than VPI

• Other workshops• Workshops do not always know the wagons• ECM TRW doesn’t know the workshops• Not yet a standard for data exchange, not yet

computerized• Mostly according VPI

ECM certification of workshops (II)

• Situation end 2013

Wagon workshops: 17 workshopsVPI: 9SNCB: 1VPI / SNCB: 5Auxiliary workshops: 2

Wheels set workshops: 8 for IS2 (2 for IS2 + IS3)VPI: 6VPI / SNCB: 2 

Pneumatic component workshops: 2
