European foreword
This document (prEN 15016-1:2022) has been prepared by Technical Committee CEN/TC 256 "Railway
applications", the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 15016-1:2004.
In comparison with the previous edition, the following technical modifications have been made:
The references to standards, the clause “Terms and definitions” have been updated. The clause “Symbols and
abbreviated terms” and the clause “Preparation of technical documents other than drawings” have been
added. Microcopying has been deleted. In Annex A references to the Data Model of Part 4 have been
incorporated to show the relation between the fields of the title blocks of technical documents and the data
fields for data exchange.
This document is part of the standard series “Railway applications — Technical documents” which consists of
the following parts:
— EN 15016-1: General principles
— EN 15016-2: Parts lists
— EN 15016-3: Handling of modifications of technical documents
— EN 15016-4: Data exchange
The scope of Part 1 to 3 is the complete railway applications. However, the scope of part 4 is rolling stock only
because this is the typical application field for the specified data exchange.
The Annexes A and B are normative.

In railway business, the customer very often requires, as part of a contract, technical documents in a certain
form. In order to support co-operation and effective exchange of information between customers, suppliers
and partners, it is necessary to have the document requirements precisely defined.
This document refers to EN, ISO or IEC standards dealing with technical documents. In cases where ISO or IEC
standards are not sufficiently precise, this standard gives specific details. These additions to ISO and IEC
standards facilitate the exploitation and administration.
These requirements have been drawn up in order to accommodate:
— the large variety of users;
— ease of documents transfer;
— any specific series of documentation related to the railway material they define.
Special consideration has been given to those producing drawings by computer and their reproduction
without loss of quality.
NOTE The range of documents covers documents such as specifications, conditions for acceptance or further
technical specifications which cannot be graphically represented. This is meant to highlight the difference between
“graphical representation” and “verbal description”.

drawings for railway applications. It complies with the requirements of EN, ISO or IEC Standards for technical
drawings. It applies to technical drawings for railways, irrespective of technology i.e. mechanical, pneumatic,
hydraulic, electronic etc.
The document applies throughout the total life span of the drawings. It applies to all the railway organizations
and parties concerned with technical drawings, and to suppliers preparing drawings for railway applications.
This document does not apply to the technical contents of the document. Neither does the standard apply to
building documentation.

4 Symbols and abbreviated terms
For the purposes of this document, the following abbreviation applies.
original equipment manufacturer
5 Preparation of drawings
5.1 Layout
5.1.1 Composition
Any document shall be given an identification number.
A set of drawings describing an assembly, a product or an installation will normally by various means (drawing
lists, document control lists etc.) be formed as an entity. Parts lists mainly list details of an assemblage or
collective drawing at a certain level. All of these parts lists may be produced either on drawing forms or parts
of drawings or as documents affiliated to the company's administrative system.
Each different part or different assembly shall have a separate identification number.
It is recommended that the parts list forms a separate document (see EN 15016-2). Alternatively, the parts list
may be entered on the same sheet as the drawing above the title block.
5.1.2 Special cases
It is permissible to represent similar parts or assemblies on a drawing.
5.1.3 Applications
If required, the applications or the identification number of the document indicating the relations between the
drawing and the applications should be noted in the title block of the drawing or parts list.
5.1.4 Multiple sheets
Multiple sheet drawings marked with the same registration or identification number shall be provided with a
sequential sheet number. In addition, the total number of sheets shall be shown on sheet 1, for example:
“Sheet No. n/p”
n is the sheet number;
p is the total number of sheets
(see ISO 7200).

5.1.5 Avoiding duplicate indications
All indications relating to standards, dimensions, materials and unit mass of parts involved in the composition
of an assembly should preferably be indicated on the parts lists of the parts concerned. If, for information
purposes, a dimension has to be repeated on the assembly drawing, it is to be written in brackets.
This remark shall not apply to specifications.
For example: indivisible or welded assemblies can have specific dimension and tolerance at their own level
even if the nominal dimension value is the same.
5.2 Characteristic features
5.2.1 General
For sizes and layout of preprinted drawing sheets EN ISO 5457 shall apply.
5.2.2 Drawing sheet or base
Drawing sheets used for the preparation or printing of drawings should have a mat surface. Drawing sheets
from polyester for which ISO 9958-1 and ISO 9958-2 apply should have a minimum wideness of 50 mm.
Drawing sheets from tracing paper according to ISO 9961 should have a minimum grammage of 90 g/m and
standardized (writing) paper according to EN ISO 216 should have a minimum grammage of 70 g/m .
Drawing sheets shall be chosen with a view to obtaining the best contrast between background and
representation according to EN ISO 6428.
5.2.3 Drawing sheet sizes
The original drawings shall be made to a standardized drawing sheet size electing the smallest size permitting
adequate legibility.
The standardized sizes of the original drawings and their reproductions shall be selected from EN ISO 5457.
5.2.4 Permanent layout features Title block
A title block shall appear on all drawings. It shall contain the necessary headings for identification and use
according to ISO 7200.
It is recommended to use the same title block on all sheets of the drawing. It is permitted to use a reduced title
block on the sheets following sheet 1. This block shall, as a minimum, have the same identification zone. The
compulsory part of the title block is defined in Annex A. Its location is independent of the direction of reading
adopted for the drawing.
In the normal reading position, the title block is situated at the bottom right-hand corner of the frame, the
drawing sheet being viewed:
— in the portrait (vertical) position for the A4 size;
— in the landscape (horizontal) position for the A3 to A0 sizes according to EN ISO 5457.
For the preparation of documents used in electrotechnology, see EN 61082-1. Copyright and exploitation rights
The designation shall be in accordance with ISO 16016. Exploitation rights shall be indicated. The name of the
legal owner or the name of the creator of the drawing shall be written in the title block. Information concerning
also existing exploitation rights can be indicated inside or outside the drawing field, where appropriate.

oSIST prEN 15016-1:2022
prEN 15016-1:2022 (E) Intellectual property
The designation shall be in accordance with ISO 16016. Protection rights should be indicated at an appropriate
place inside or outside the drawing field of the drawing and/or in the parts lists.
5.3 Execution
5.3.1 Graphical representation of layout Arrangement of the drawing sheet
The arrangement of the drawing sheet shall be in accordance with EN ISO 5457:1999, 4.1. Presentation methods, symbols and scales
For the relative position of views, use shall be made of the First Angle projection method (earlier known as
European method of representation Method E) as defined by EN ISO 128-3.
The simplified and symbolic representation specified by European or International Standards should be
adopted in preference to text.
Scales according to EN ISO 5455 are recommended. Leader line
Leader lines shall preferably be terminated by a dot or an arrow, placed on the pa
