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).

Scope

This European standard specifies the safety requirements and tests for rail locomotives for use in
underground mining (i.e. mine locomotives) and other underground workings (e.g. tunnelling locomotives).
1.1 This European standard deals with the technical requirements to minimise the hazards listed in clause 4
which can arise during the commissioning, the operation and the maintenance of locomotives when carried
out in accordance with the specifications given by the manufacturer or his authorised representative.
1.2 This European standard does not address the special hazards associated with the rack drive of rack
and pinion locomotives.
1.3 This European standard does not deal with radiation and vibration. It does not address remote control
locomotives or operation in potentially explosive atmospheres. Hazards due to noise are excluded from this
standard, but a separate standard is in preparation where hazards due to noise will be addressed.
1.4 This European standard applies to locomotives which are manufactured after the date of issue of this
standard.

General/basic requirements

5.1.1 For the application of EN 953, EN 982, EN 983, EN 457, EN 563, EN 547 and EN 60204-1 the
manufacturer shall carry out an adequate risk assessment for the requirements thereof where choice is
necessary.
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
system.

5.1.5

Suspension systems with self-damping, e.g. multi-leaf springs, may not need a separate shock absorbing

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).

11


BS EN 1889-2:2003+A1:2009
EN 1889-2:2003+A1:2009 (E)

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
5.4.1.1

Hydraulic systems
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 fireresistant 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)

12

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


BS EN 1889-2:2003+A1:2009
EN 1889-2:2003+A1:2009 (E)

sufficiently hot to reach 80 % of the flashpoint of the hydraulic fluid for which the system has been
designed.
