RSD - Bogies for Rolling Stock

Since its inception in 1940, RSD, a division of DCD-DORBYL, has established itself as a leading supplier of locomotives, railway wagons and related goods to the national railways, mining and industrial users throughout the local and international markets. RSD has the technical expertise, experience and facilities to design and manufacture a broad range of products to meet their individual customers' needs.

For the rail industry, RSD designs, manufactures, refurbishes and services a complete range of rolling stock including locomotives, coach bodies, wagons and bogies. RSD has designed and manufactured more than 130,000 wagons, 1,000 surface locomotives and 4,000 underground locomotives.

Bogies for all types of rolling stock

RSD have supplied nearly all the locomotive and passenger cars as well as the majority of freight bogies for the South African Railways and also for various other African and overseas customers over 50 years.

The following are special features of our designs:

• They are user-centered, designed for specific operational conditions
• The bogies are designed for safety and reliability
• We are flexible and a design will fit the user's requirements with relative short development and delivery times
• Our designs are robust and ensure optimum availability and mission reliability
• Our bogies offer a minimum life cycle cost, they are supplied with one-piece cast steel frames for a virtually indefinite service life

Two-axle and three-axle locomotive bogies

For locomotives three-axle and two-axle bogies have been designed, both off-flange (self-steering) and on-flange curving (conventional) for both general freight and heavy haul applications. The bogies offer zero inter-axle mass-transfer.

For passenger vehicles we designed and supplied mainline and suburban coach bogies as well as high-speed bogies. They are designed for comfort but provide the maximum operational safety.

On the freight side we supply the Scheffel CROSS-ANCHOR self-steering bogie. This bogie is in a class of its own in reduction of wheel and rail forces and wear.

Rolling stock technology

We constantly strive to be at the forefront of rolling stock technology, and can draw on vast depths of experience, expertise and resources in this field. RSD has long been a leader in the development and supply of rolling stock in South Africa and export markets.
