5 Classification
This document covers a wide variety of different bogie types. For reference purposes it is convenient
to assign them to different categories. Although identified generally in terms of vehicle types, the
selection of the category for a bogie should also take into account the structural requirements of the
bogie frame. The structural requirements for bogies in a particular category are not unique and shall
always be specified by the customer according to the operating requirements, using the principles
presented in this document. It is the responsibility of the customer to decide to which category a bogie
shall be allocated. There will be differences in choice between customers. This is to be expected and
10

---------------------- Page: 12 ----------------------

SIST EN 13749:2005
EN 13749:2005 (E)
should not be considered as conflicting with this document. Some bogies may not fit into any of the
defined categories.
category B-I bogies for main line and inter-city passenger carrying rolling stock including high
speed and very high speed vehicles, powered and un-powered;
category B-II bogies for inner and outer suburban passenger carrying vehicles, powered and un-
powered;
category B-III bogies for metro and rapid transit rolling stock, powered and un-powered;
category B-IV bogies for light rail vehicles and trams;
category B-V bogies for freight rolling stock with single-stage suspensions;
category B-VI bogies for freight rolling stock with two-stage suspensions;
category B-VII bogies for locomotives.
NOTE The classifications are similar to (but not wholly consistent with) those adopted for vehicle bodies in
EN 12663 [9]. They are not exclusive and more may be added as information becomes available.
6 Responsibilities
The customer shall provide the supplier with a detailed description of the requirements of the bogie
design in the form of a technical specification incorporating all appropriate mandatory regulations. The
customer shall also define the parts of the acceptance procedure (clause 9) and the quality
requirements (clause 10), which he specifically requires.
The customer shall specify the way in which the supplier is to provide evidence to show that the
requirements have been met.
NOTE If the customer is unable to define the specification completely the supplier may propose a
specification and submit it to the customer for approval. It is the supplier’s responsibility to design the bogie frame
in accordance with the specification.
7 Contents of technical specification
7.1 Scope
The technical specification shall consist of all the information describing the functional requirements of
the bogie frame and the interfaces with associated components and assemblies. It shall also comprise,
as a minimum, the general requirements of use, the conditions associated with the vehicle equipped
with the bogies, the operating characteristics, the conditions associated with maintenance and any
other particular requirements of the customer.
7.2 General requirements
The customer shall indicate the type of bogie required in terms of its use in accordance with the
categories in clause 5. The customer shall also indicate in the technical specification the intended life
of the bogie, its average annual distance run and its total distance run.
7.3 Vehicle conditions and interfaces
The specification shall include, but not be limited to, information on:
11

 vehicle geometry (e.g. available space, position of the centre of gravity);
 body–bogie connections (e.g. mechanical, pneumatic, electric);
 braking equipment;
 motors and transmission;
 tilt systems (where applicable).
7.4 Operational characteristics
The specification shall include, but not be limited to, information on the characteristics to which the
bogie is to be designed:
 loading conditions (e.g. changes in payload and frequency, dynamic load spectra);
 method of loading (e.g. progressive or sudden);
 maximum axle loads;
 maximum operating speed;
 speeds on curves and cant deficiency;
 starts and stops (i.e. number and frequency, acceleration rates, deceleration rates, including
effect of wheel slip/slide control);
 exceptional conditions (e.g. derailments, lifting, allowable instability).
7.5 Line characteristics
The specification shall include information on all the characteristics of the railway network for which
the bogie is to be designed that have an influence on the loads applied to the bogie, including the
following:
 profiles of the tracks, including service depot tracks, (e.g. radius of curves, number of curves,
percentage of distance covered on straight lines and on curves, maximum and normal levels of
twist, percentage of use on service depot tracks, number of junctions, cant);
 types of track (e.g. classification of quality including construction, roughness and irregularities);
 loading gauge.
7.6 Environmental conditions
The specification shall include information on the characteristics of the environment that can have an
influence on the behaviour of the bogie frame and that the bogie frame shall be designed to withstand,
including:
 climatic conditions
