Submit a request

SD-50 rail baseplate is a track superstructure element designed for installation under R-50 type rails on wooden sleepers. It ensures uniform distribution of rail pressure, prevents sleeper wear, and improves track stability. It is used on mainline, station, and industrial railway tracks.

Description and Design

The SD-50 baseplate is manufactured in accordance with TU U 30.2-31932840-002:2021 (GOST 12135-75) from hot-rolled structural steel. The design features a profile matching the R-50 rail foot and four fixing holes: two oval holes to compensate for thermal rail movements and two round holes for secure fastening. The baseplate provides tight contact with the sleeper and prevents loosening of fastenings.

Profile geometry fully complies with the R-50 rail standard;
Contact surfaces under the rail foot are machined for tight fitting;
Anti-corrosion protection: phosphating or oil-based protective coating;
Designed for axle loads up to 210 kN;
Service life: at least 30 years under standard operating conditions.

Application

SD-50 baseplates are used when laying railway tracks with R-50 rails on wooden sleepers. They are applied on general-purpose and industrial lines, including stations, access tracks, and turnout areas. Compatible with KB-50 and KBL-50 fastening systems, as well as 16×165 mm rail spikes or 24×150 mm rail screws.

Advantages of SD-50 baseplates:

Uniform load distribution on the sleeper;
Reliable rail fastening and track stability under dynamic loads;
Reduced wear of wooden sleepers and vibration impact;
Easy installation and high maintainability;
Full compliance with Ukrzaliznytsia requirements and TU U 30.2-31932840-002:2021.

Supply and комплектation

SD-50 baseplates are supplied in batches according to standard specifications;
Each item undergoes inspection of geometry, thickness, and surface quality;
Available as complete sets with rail spikes, screws, and clips upon request;
Delivery across Ukraine by road or rail transport from Prombudkoliya warehouses.
