Submit a request

Turnout frog (crossing) is a key element of a railway turnout, designed for crossing and guiding rail tracks when rolling stock is transferred from one track to another. It ensures smooth and safe passage of wheelsets through the rail intersection zone. Frogs are used on mainline, station, and industrial railway lines as part of various turnout configurations.

Description and design

The frog is manufactured in accordance with GOST TU U 30.2-31932840-001:2021 and consists of a nose (point) and wing rails connected to the stock rails. The design may be assembled (from rolled rail elements) or solid cast, made of high-strength steel. The running surfaces are subjected to hardening treatment, providing high wear resistance and resistance to impact loads.

Material: high-manganese steel 110G13L or rolled steel 20KhGT;
Manufactured by welding or casting followed by machining;
Running surfaces are hardened by induction hardening or wear-resistant surfacing;
Accurate geometry ensures smooth wheelset passage;
Service life: not less than 1 billion gross tonnes under proper maintenance.

Application

Turnout frogs are used in all types of railway turnouts (SPR-50, SPR-65, SPR-85, etc.) on public and industrial railways. They provide rail crossing and wheel guidance and are installed in both assembled and solid cast turnouts on sections with various speeds and axle loads.

Advantages of turnout frogs:

High strength and resistance to dynamic loads;
Long service life and increased wear resistance of the running surface;
Precise geometry ensuring smooth running;
Compatibility with different turnout types;
Compliance with DSTU EN 13232 standards and the requirements of Ukrzaliznytsia.

Supply and delivery

Supply of turnout frogs for SPR-50, SPR-65, SPR-85 turnouts;
Manufacturing of assembled and solid cast frogs according to customer drawings;
Each product undergoes geometry, strength, and metal hardness inspection;
Delivery across Ukraine by road or rail from the warehouses of Prombudkoliya.
