Track maintenance machines

Franz Messerli

track maintenance machines
EFRTC General Meeting, Paris, 11th June 2010Track maintenance machines
  • On-track machines look more and more similar to freight wagons, passenger coaches or locomotives ?

Franz Messerli

track maintenance machines7
EFRTC General Meeting, Paris, 11th June 2010Track maintenance machines
  • They are built as standard railway vehicles that can be incorporated in a train formation or for example tamping machines can transit on the track under their own power.

Franz Messerli

track maintenance machines8
EFRTC General Meeting, Paris, 11th June 2010Track maintenance machines
  • But other than conventional rolling stock who transport passengers or carry freight the main purpose of track maintenance machines is to maintain and renew the tracks.
  • They are manufactured in small numbers, tailored to customers and market requirements thus almost never at 100% identical to another machine.

Homologation process in the nineties

  • B 66 U for DB in 1993
  • BZA 82 in Munich
  • One handwritten page A4 of requirements

Franz Messerli

today s approval process12
EFRTC General Meeting, Paris, 11th June 2010Today’s approval process
  • Basic requirements are covered by the European Standard EN14033-1/-2/-3 “Rail bound construction and maintenance machines”

Franz Messerli

today s approval process13
EFRTC General Meeting, Paris, 11th June 2010Today’s approval process

The following documents, calculations and proof must be delivered to the Railway Authorities

  • Machine and bogie frame strength
  • Proof of strength of mounted parts
  • Resistance to longitudinal compressive load
  • Powered and idle wheel set calculations
  • Demonstration of safety against derailment
  • Demonstration of running safety
  • Demonstration of brake performances
  • Demonstration of electrical contact resistances
  • Demonstration of equipment to be monitored (pressurised tanks such as brake air reservoir, fuel tanks, diesel, hydraulic, pressure valves)
  • Etc.

Some experiences made by MATISA with today’s homologation process

EFRTC General Meeting, Paris, 11th June 2010
  • Over the last 15 years the MATISA internal amount of effort and cost for a European machine approval has been multiplied by big factors. For MATISA Switzerland the numbers are as follow:
  • 1993 = 0.5 person for homologation 2010 = 10 people in testing and approval department
  • 5 people in calculation department
  • Design engineers spend 20 % of their time for the elaboration of approval related documents.
  • Not counted management efforts used to overcome almost daily new problems and requirement.

Some experiences made by MATISA

some experiences made by matisa16
EFRTC General Meeting, Paris, 11th June 2010Some experiences made by MATISA
  • Cost comparison

B 66 UC Salcef, 2005, under old approval process

B 66 UC Fourchard, 2009, under today’s approval process, 12 times more in external cost

Franz Messerli

some experiences made by matisa17
EFRTC General Meeting, Paris, 11th June 2010Some experiences made by MATISA
  • Difficulties to keep up with the huge number of EU Standards
  • Largely dependant on the person which signs off approval

  • Request of independent reviews by external certified testing bodies for:

Brake testing

some experiences made by matisa21
EFRTC General Meeting, Paris, 11th June 2010Some experiences made by MATISA
  • Testing proof of safety against derailment for a 3 point suspension system, external cost of more than € 30K

  • Machine and bogie frame calculations

Franz Messerli

some experiences made by matisa24
EFRTC General Meeting, Paris, 11th June 2010Some experiences made by MATISA
  • Little difference made between on-track machines and Locomotives/Rolling stock
  • Tamping machine, re-testing of brake performance in the country of destination = nearly impossible
  • WTM S+C carrying wagons
  • 10 WTM approved for Germany
  • 39 WTM delivered into 3 different countries, including Germany
  • No known safety issue over last 10 years of operation
  • To approve latest 3 for Germany it becomes necessary to go through whole new process again.

Franz Messerli

some experiences made by matisa25
EFRTC General Meeting, Paris, 11th June 2010Some experiences made by MATISA
  • Approval bodies do not care about cost, efforts and delivery delays due to the complexity of the homologation.

Franz Messerli

outlook27
EFRTC General Meeting, Paris, 11th June 2010Outlook
  • Future homologation will be covered by TSI’s which are EU law
  • Notified bodies (NoBos) will carry out approval against standards and elaborate technical file for submission to the national authorities
  • The national authorities of a 3rd country should accept verification against a standard that had been carried out by the NoBo of another country

Franz Messerli

outlook28
EFRTC General Meeting, Paris, 11th June 2010Outlook

The TSI Noise has already to be applied for the approval in certain countries. The conditions have been made easier.

Some of the conditions today are:

  • No rain
  • No snow
  • Little wind
  • Approved track (shape of the countryside, track material, rail roughness
  • 1000 km travelled

Franz Messerli

summary30
EFRTC General Meeting, Paris, 11th June 2010Summary
  • Efforts and cost for approval have dramatically risen over the last years.
  • It seems very likely that the introduction of the TSI will further increase efforts, expenses and delivery times.
  • On-track machines should not be put into the same category as locomotives or freight wagons.
  • On-track machines are often manufactured in small numbers tailored to customer needs

Franz Messerli

summary31
EFRTC General Meeting, Paris, 11th June 2010Summary
  • On-track machines travel much less over then network than other rolling stock
  • The resistance of the national approval bodies and external independent experts will in our view still prevent the application of the Interoperability principle with the explanation that national specifications and procedures still apply.
