Full title and description

STB DIN EN 13145:2001-04 — Railway applications — Track — Wood sleepers and bearers. German national adoption of the European standard EN 13145:2001 defining species, quality, forms, dimensions, tolerances, durability and preservative treatment requirements for wooden railway sleepers and bearers used in track and switchwork.

Abstract

This standard specifies the technical requirements for wooden sleepers and bearers intended for railway track and turnouts: definitions and terminology, approved wood species, quality grading and defects, manufacturing and dimensional tolerances, durability and preservative treatment classes, factory production control, marking and traceability. It applies only to wood sleepers/bearers and excludes other track timbers and customer‑specific finishing processes.

Scope

Defines requirements for wood sleepers and bearers used in ballasted and non‑ballasted track and in turnouts: permitted species and origins, grading rules for defects (knots, checks, shakes, included sapwood, red/grey heart, etc.), nominal forms and dimensional tolerances, durability and preservative treatments (penetration and retention classes), factory production control, marking and traceability. It does not cover other timber products used in the track or customer‑specific finishing operations.

Key topics and requirements

• Terminology and definitions for sleepers, bearers and timber defect categories (heartwood, sapwood, included sapwood, red heart, wane, etc.).
• List of acceptable wood species (certain European softwoods and hardwoods and selected tropical hardwoods) and rules on origin and grading.
• Forms, nominal dimensions and dimensional tolerances for standard sleeper and bearer shapes; permitted deviations and angular tolerances.
• Durability classes, preservative treatment requirements (penetration and retention), and references to laboratory and field test methods.
• Quality control and inspection rules: permitted/prohibited defects after seasoning, sampling and acceptance criteria.
• Factory production control, marking, traceability and documentation to demonstrate conformity with the standard.

Typical use and users

Primary users are railway infrastructure authorities, track engineers and designers, contractors specifying or procuring sleepers, timber suppliers and sawmills, preservative treatment plants, testing laboratories and conformity assessment bodies. Typical applications include specification of sleepers for new track construction and renewals, procurement tender documents, factory acceptance and site inspection criteria, and guidance for preservative treatment selection to meet required service life.

Related standards

Common normative and related references used with EN 13145 include standards on preservative performance and testing and timber durability such as EN 252 (field tests for preservative effectiveness), EN 351‑1 (preservative penetration/retention), EN 350‑2 and EN 335‑1 (durability/hazard classes), EN 599 (performance of wood preservatives) and the EN 844 series (timber terminology). EN 13145 is part of the wider set of CEN railway track standards maintained by CEN/TC 256.

FAQ

Q: What is this standard?

A: DIN EN 13145:2001-04 is the German adoption of EN 13145:2001 — a CEN European standard that sets requirements for wooden railway sleepers and bearers (species, quality, dimensions, durability and preservative treatment).

Q: What does it cover?

A: It covers definitions, permitted wood species, grading rules for defects, standard forms and dimensional tolerances, durability classes and preservative treatment requirements, factory production control, marking and traceability for sleepers and bearers used in track and turnouts. It does not cover other timber items used in the track or customer‑specific finishing.

Q: Who typically uses it?

A: Railway infrastructure owners/operators, track designers and engineers, timber suppliers and treatment plants, testing laboratories, procurement and quality inspectors — anyone involved in specifying, supplying, treating or inspecting wooden sleepers and bearers.

Q: Is it current or superseded?

A: The original DIN EN 13145:2001-04 text has been superseded/updated by a consolidated edition incorporating Amendment A1 (EN 13145:2001+A1:2011) and later national implementations; the 2001 national adoption is listed as withdrawn in many national catalogues and users should reference the latest consolidated EN 13145 edition or their national implementation for current requirements.

Q: Is it part of a series?

A: Yes — EN 13145 sits among CEN/TC 256 railway track standards and is typically used alongside other standards for preservative testing, timber durability and track components (see EN 252, EN 351‑1, EN 350‑2, EN 599, EN 844 series and related railway track standards).
