EU Directives & TSIs
TSIs are of same legislative level as
directives = essential requirements.
No deviation permissible !
EFRTC-UNIFE OTM Task Force, General Meeting, Prague, 22nd June 2012
Current situation
• Two fundamentally different trends:
A) Either the European position will become
stronger in the long term view (TSI will become
mandatory for OTM in the future)
B) or OTMs remain on the long-term view in the
field of national approval processes
• There are players which act with pressure for both
strategies
• OTM Task Force strategy in line with the objectives
i.e. European harmonisation as much as possible
but respecting justified national specific conditions
EFRTC-UNIFE OTM Task Force, General Meeting, Prague, 22nd June 2012
Proposed Strategy (1)
• OTM has to be a separate category in TSI RST
which shall be divided in two sub groups:
• OTM-1: OTM category without any Open Point
in TSI RST
• OTM-2: OTM category with some Open Points
to be handled nationally by NNTR (notified
national technical rules)
• All essential requirements for transport mode
covered by TSI RST (requirements in TSI RST shall
base on EN 14033-x)
• EN 14033-x shall be a harmonised standard (not
cited in TSI to ensure, that it is handled as standard and not
as law)
EFRTC-UNIFE OTM Task Force, General Meeting, Prague, 22nd June 2012
Proposed Strategy (2)
• For vehicles of category OTM-1: mutual recognition of
one authorisation for placing machine into service into
all member states (article 23 of Interoperability Directive)
• For vehicles of category OTM-2: authorisation shall
only be performed for open points (national
parameters) – the same to be applied for x-acceptance
procedures
• For working mode, OTMs can not be covered by TSI
RST - assessment against machinery directive and
EN 14033-x as harmonised standard
• Geographical scope of TSI RST to be extended to the
whole network (with some exceptions)
EFRTC-UNIFE OTM Task Force, General Meeting, Prague, 22nd June 2012
Proposed Strategy (3)
• TSI RST are still voluntary for OTMs – no problem
for the near future but applicant has a choice between TSI
or national authorisation
• Actions needed to follow the proposed strategy:
− Prepare EN 14033-x in a way that it covers the essential
requirements of the TSI RST
− Ensure, that EN 14033-x are harmonised standards for
the TSI RST as well as the Machinery Directive (without
any direct citation in the TSI respectively the Directive)
− Ensure, that for OTM-1 the mutual recognition is granted
− Ensure, that for OTM-2 the national approval is based on
harmonised standards with TSI and multi-national
approvals are performed only for specific national
requirements (open points) agreed for cross acceptance
procedures
EFRTC-UNIFE OTM Task Force, General Meeting, Prague, 22nd June 2012
OTM definition/scope in TSI
• Mobile railway infrastructure construction and maintenance
equipment or on-track machines (OTM) are vehicles specially
designed for construction and maintenance of the track and
infrastructure
• OTMs are used in different modes: working mode, transport
mode as self-propelling vehicle and/or as a hauled vehicle.
• OTM are only classified as a separate OTM category in TSI.
They shall not fall into any other category or unit of rolling
stock as it stands in current version of TSI
• No road/rail-vehicles according EN 15746-x
• No gauge-changing vehicles
• Infrastructure inspection vehicles and Switch transportation
wagon are included in the category OTM with some specific
conditions
EFRTC-UNIFE OTM Task Force, General Meeting, Prague, 22nd June 2012
Category OTM-1
All requirements of category OTM conform to TSI
• maximum speed in any mode not higher than 150 km/h
• no electrical power supply (electrical traction system is
however possible)
• Buffers, draw-gear and screw coupling systems for manual
coupling at both ends of he OTM
• within the gauge G1 according to UIC 505-1
• no distance between 2 axles higher than 17.5m
• no distance between 2 axles lower than ai [mm] = vmax
[km/h] x 7.2
• no distance between end of vehicle (buffer) and first axle
higher than 4.2m
• minimum distance between first and last axle of an unit is 3m
EFRTC-UNIFE OTM Task Force, General Meeting, Prague, 22nd June 2012
Category OTM-1 (continued)
•
•
•
•
•
minimum wheel radius 450mm
minimum axle load 5t at axles with no block brake
minimum axle load 3.5t at axles with block brake
no composite brake blocks
compatible to trackside hot box monitoring systems
according EN 15437- 1:2009
• wheel profiles S1002 or GV 1/40 with spacing of active
faces between 1420 and 1426 mm
• maximum wheel/rail adhesion of 0.13 for the service brake
and 0.12 for the parking brake
• not operated by radio control system from ground (only
from driver's cab)
EFRTC-UNIFE OTM Task Force, General Meeting, Prague, 22nd June 2012
Category OTM – 2
• Category OTM – 2 fulfils requirements of OTM but
not all essential requirements for OTM – 1 as
specified by TSI
• For this category there are some open points –
specific national requirements to be met
• The authorisation of OTM-2 categories shall only be
performed against specific national requirements
subject to an agreement on the mutual recognition of
authorisations by MS against agreed essential
requirements of OTM (EN 14 033 standard
harmonised under Interoperability Directive)
• The list of the specific national requirements shall
be a part of harmonized EN 14 033
EFRTC-UNIFE OTM Task Force, General Meeting, Prague, 22nd June 2012
Major critical items
OTM are not classified in current TSI as a special category
and they can fall under an other category and/or unit of
rolling stock. This may impose the additional requirements on
OTM authorisation which are either excessive or not at all
relevant to OTM
Besides all current open points in TSI such as e.g.
specification of events to be recorded, fire protection in
tunnels, etc. The most critical items for OTM are:
• Clear definition of the scope of the dynamic running test
• Scope of the specifications for braking systems and
tests in TSI and EN 14 033-1
• Composite brake blocks – noise issues
• Signalling systems and ETCS requirements
• Structural requirements for bogie frames and wheels
• Event recording devices
EFRTC-UNIFE OTM Task Force, General Meeting, Prague, 22nd June 2012
Next steps
• To discuss the comments received and to circulate the final
version of the report to EFRTC and UNIFE members/experts
concerned
• To start the dialog with NSA of major countries at the national
level (e.g. German contractors and manufacturers have already
met EBA and received its support for proposed approach to ERA)
• The same approach to be initiated in France, UK, Italy, etc
• To pursue informal contacts with ERA (the informal technical
meeting with ERRA will be held at UNIFE on 05.07.12)
• If the proposed strategy is agreed with ERA then to translate the
outcome of the report into the ERA request format for the
modification of TSI Loc & Pas in the current revision process
• To assure that EN 14 033-1 will be a harmonised standard to TSI
Loc & Pas – coordination of actions with CEN WG 5
