Advancing African Railways: Amsted Reelin’s Innovative Bogie Technology Showcased at SARA 2023
During the recent Southern African Railway Associations (SARA) – Conference and Exhibition 2023, Reesh Naidoo, the Executive Director of Amsted Reelin, provided a compelling presentation. His talk focused on the need for revolutionising railway operations in Africa, with a special emphasis on the modernization of Bogie technology.
The Need for Modern Bogies in African Railways
Naidoo began by emphasising the importance of using modern technology in rail operations, drawing parallels to the evolution seen in personal vehicles like cars and freight trucks. He pointed out that, unlike the automotive sector, the African rail market still heavily relies on an outdated underframe and bogie designs from the 1970s. These older bogies, often refurbished and resold, are not only technologically obsolete but also require much higher maintenance, which is costly, in addition to the spares which all together negatively contribute to a railway operator’s ability to efficiently utilise their fleet.
In response to these challenges, Amsted Reelin, a collaboration between Amsted Rail (US) and Reelin Group (South Africa), has made available to the region a new generation of bogies. The ‘Motion Control Bogie,’ this innovation is available for Cape Gauge Railways as well as Standard Gauge Railway, and is characterised by its self-steering, lightweight design.
Importantly, these bogies are fully interchangeable with existing fleet models, matching the predecessors’ functionality while offering reduced costs and ownership expenses. In addition, the Motion Control Bogies boast increased load capacity and enhanced reliability, representing a significant leap forward in bogie technology.
Key Features and Cost-Efficiency
The Motion Control Bogie features a simple, three-piece design with fewer components for easier maintenance. A critical innovation in these bogies is the steering pad, a green component that significantly enhances steering capabilities. Naidoo provided a detailed breakdown of the bogie’s total cost of ownership, highlighting its economic viability.
With proper maintenance, a new bogie is expected to last 45 years. A heavy maintenance cycle is required every 1.5 million kilometres, which is roughly equivalent to approximately 15 years. The cost for this in today’s value is $2,000. The same applies to the second heavy maintenance after another 15 years, so at year 30 or 3 million kilometres, another heavy maintenance is due and similarly for the third cycle. Taking the bogie lifespan to 60 years, with the operational cost of ownership estimated at $6000 over the useful life of the bogie.
Extending Lifespan and Offering Training
Naidoo also mentioned that Amsted Reelin provides maintenance training workshops, empowering customers to manage their Motion Control Bogies efficiently at their own depots. In a specific case study related to operations on the Bangula-Marka railway line, the exceptional engineering and design of the bogie could potentially last up to 80 years!
Comprehensive Railway Solutions:
Beyond bogies, Amsted Reelin offers a wide range of undercarriage products for railcars, including bearings, wheelsets, draft gears, end-of-car systems, slack adjusters and braking equipment. Naidoo emphasized that the company aims to provide a complete solution for the undercarriage requirements of rail vehicles.
Digital Monitoring and Predictive Maintenance:
Lastly, Naidoo touched upon Amsted Reelin’s digital solutions, including a tracking and monitoring device for wagons. This unpowered device, with a long battery life, is pivotal for predictive maintenance, allowing operators to monitor the status of their wagons and anticipate maintenance needs.
Reesh Naidoo’s presentation at SARA 2023 not only highlighted Amsted Reelin’s innovative Bogie technology but also showcased the company’s commitment to transforming rail freight operations in Africa through cutting-edge solutions and comprehensive support.
