EN 1889-2:2003+A1:2009 (E) 4 Introduction This European Standard is a type C standard as stated in EN 1070. The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the scope of this document. The standard takes into account the current state of the art and technical facilities to use in order to exclude or prevent, as far as possible, hazards when rail locomotives are used underground. When compiling this standard it has been assumed that:  components are: a) designed in accordance with good engineering practice, taking account of expected shocks and vibrations and calculation codes, including all failure modes; b) of sound mechanical and electrical construction; c) made of materials with adequate strength and of suitable quality; and d) free of defects. e) harmful materials, such as asbestos are not used; f) components are kept in good repair and working order, so that the required dimensions remain fulfilled despite wear; g) negotiations have taken place between the manufacturer or authorised representative, purchaser and/or user (e.g. for fire resistant fluids, safety equipment and load restraining devices).

NOTE This specific risk assessment is part of the general risk assessment relating to the hazards not covered by this C standard. For hazards which are not covered by this standard, machinery shall conform as appropriate to EN 292. 5.1.2 All moving parts, with the exception of the wheels, drive lines and articulation area, shall be provided with guards according to EN 953. Gaps between guards and moving parts shall conform to EN 349 and EN 294. 5.1.3 Where hinged guards or covers can self-close, they shall be fitted with a support system to secure them in the open position. 5.1.4 Locomotives shall be fitted with suspension and shock absorbing systems to ensure that all wheels maintain contact with the rails and to absorb shock loading from the track. In the event of failure of the suspension system, no part of the locomotive shall contact moving parts of the running gear or be below than the upper level of the rails. This also applies to driver's cabs having their own bogie, e.g. driver's cabs of articulated locomotives. NOTE Suspension systems with self-damping, e.g. multi-leaf springs, may not need a separate shock absorbing system. 5.1.5 The front faces of locomotives shall be painted in a safety colour in accordance with ISO 3864. Locomotives shall have facilities for stowing any safety equipment (see also introduction, on negotiations). SIST EN 1889-2:2004+A1:2009



EN 1889-2:2003+A1:2009 (E) 12 5.1.6 For unintentional contact the temperature of hot surfaces inside of the locomotive are based on annex B of EN 13202:2000 for 0,5 s contact time.
For the parts that require handling during maintenance the temperature of the touchable surface shall be in accordance with EN 563 for 5 s contact time.
Where this limit cannot be achieved, see 7.1.3. Exhaust pipes within reach during operation which exceed the touchable surface temperatures given in EN 13202 for 0,5 s shall be guarded against unintentional contact in accordance with EN 953. 5.1.7 With the exception of couplings and the current collector (for trolley locomotives), all other components shall be contained within the profile of the locomotive such that they are protected against accidental damage. 5.2 Design to facilitate handling Where purpose-designed attachment points are provided they shall be designed to have a calculated minimum factor of safety of 4 on ultimate breaking load in relation to their intended load carrying capacity.
They shall be shaped to suit the lifting means intended by the manufacturer, see 7.1.2. They shall be clearly and permanently marked with their load carrying capacity, e.g. by welding. Where any such attachment points could be used to lift or move the whole locomotive this factor of safety shall relate to the service weight of the locomotive. Articulated locomotives shall be fitted with means to avoid relative movements between parts. 5.3 Couplings
5.3.1 Locomotives shall be equipped with couplings to absorb and to transfer the tensile and compressive forces to the locomotive frame. The couplings and all parts of the locomotive lying in line with it shall be designed with a minimum safety factor of 10 against failure in relation to the maximum drawbar pull of the locomotive (or locomotives where these are designed to be used in tandem), for a minimum coefficient of static friction of 0,25 for steel tyres and 0,40 for rubber or polymer derivative tyres. NOTE Characteristics of the coupling are discussed between the manufacturer and the user, see introduction on negotiation.
5.3.2 In the fully compressed position of the coupling, it shall be possible to move freely a non-deformable sphere of 250 mm diameter between the front face of the locomotive and a vertical plane perpendicular to the longitudinal axis of the locomotive at the extreme end of the coupling. 5.3.3 If it is intended that safety chains are to be used the attachment points of these shall have a minimum breaking strength of not less than 2½ times the weight of the locomotive. 5.4 Fluid power systems 5.4.1 Hydraulic systems 5.4.1.1 Hydraulic systems shall be designed and installed to conform to EN 982. 5.4.1.2 Hydraulic systems (hydrostatic and hydrokinetic) shall be designed to enable non-toxic fluids as defined in the 7th SHCMOEI Report [1] to be used to minimize risks to health. 5.4.1.3 Hydraulic systems (hydrostatic and hydrokinetic) on locomotives shall be designed such that fire-resistant fluids can be used to minimise fire hazards (ISO 7745 and SHCMOEI 7th report) or the following precautions shall be taken for all systems exceeding 10 l total capacity:
a) Hydraulic lines (rigid metal and flexible pipelines) shall be segregated from any unprotected electrical cable or equipment (see 5.5.2.3), or any part of the locomotive, the surface of which, can become SIST EN 1889-2:2004+A1:2009



EN 1889-2:2003+A1:2009 (E) 13 sufficiently hot to reach 80 % of the flashpoint of the hydraulic fluid for which the system has been designed. b) Hydraulic lines shall be shrouded to prevent flammable fluid under pressure being ejected from a leak or a burst onto a hot surface as defined in paragraph a) above, or outside the profile of the locomotive. NOTE National legislation implementing EU Directive 92/104/EEC can require the use of fire resistant fluids in hydraulic systems, see introduction on negotiation.
5.4.1.4 Hydropneumatic accumulators shall conform to EN 982. 5.4.1.5 Reservoirs for hydraulic fluids shall be protected against corrosion, be secured to the locomotive and incorporated in such a way (e.g. inside the rigid structure of the locomotive) that they are protected against mechanical damage. 5.4.1.6 The filling apertures of reservoirs for hydraulic fluids shall be within reach of an operator standing at rail level, otherwise means of access shall be provided.
The filling aperture shall be designed and positioned in such a way that any overflow or escape of hydraulic fluid is prevented under foreseeable operating conditions, including derailment.
Any cap fitted shall be secured to prevent it working loose in service and shall require an intentional action to release it.
When released it shall remain permanently attached to the locomotive. The location and marking of the filling point for any hydraulic system shall be designed to avoid the inadvertent introduction of other substances (e.g. liquid fuel, water, sand) into the hydraulic system. 5.4.1.7 Reservoirs for fluids shall have a drainage device at their lowest point. Provision shall be made for free flow and safe catchment of fluid without coming into the proximity of hot parts or electrical equipment. The design intent shall be to prevent any fluid residues collecting in parts of the locomotive outside the hydraulic system. 5.4.1.8 Hydraulic pressure relief valves shall only allow hydraulic fluid to be discharged back into the system. 5.4.1.9 Hydraulic lines shall be designed as rigid metal lines or as flexible hoses. Materials for hydraulic hoses and their components shall be in accordance with ISO 6805 and shall be fire-resistant so that it will self extinguish within 30 s of removal of the flame in accordance with EN ISO 8030. Safety factors of the hose assembly (including end fittings), shall be 2:1 for the dynamic pressure and 3:1 for burst pressure. Hydraulic lines shall be designed to take into account the relative movement between components. NOTE Where hose reinforced with steel wire is used consideration needs to be given to fatigue aspects.
Hydraulic hoses containing fluid with a pressure exceeding 5 MPa (50 bar) and/or having a temperature exceeding 50 °C and located within 1 m of the driver or operator shall be guarded, see 5.1.1 and 5.1.2.
Parts or components can be considered as guards.
NOTE Line connections should be limited in number and designed to minimise any possibility of leakage during operation. 5.4.1.10 Tanks for hydraulic fluid shall be fitted with a mechanically protected fluid level indicator with at least minimum and maximum operating levels. 5.4.1.11 Means shall be provided to monitor hydraulic fluid temperature and to warn the driver when the fluid temperature approaches the maximum specified by the manufacturer (see also 5.14).
