Industrial Wireless Network Design for Railways
Blog Category: Industrial Ethernet

Posted by: Richard Weatherburn on December 09, 2015

Just as industrial automation systems in plants are migrating from fieldbus to Ethernet, so too are the networks that control modern transportation systems. Let’s think for a moment about railway systems, which include everything from subway or metro systems in cities to light rail networks in major urban areas to high-speed trains connecting states or countries.

New requirements such as passenger demands for Internet access, the need for flexible train re-configurations and ever increasing productivity demands are driving rail organizations to adopt industrial Ethernet. While traditional fieldbus technology is simple and very reliable, Ethernet offers the benefits of flexibility, ease-of-use and real-time communication.

Needless to say, safety and reliability are of paramount importance for transportation systems. How then can Ethernet systems, especially when they incorporate industrial wireless technologies, meet both application needs and high reliability requirements?

3 ICS Security Tips for Public Transportation Systems
Blog Category: Industrial Security

Posted by: Richard Weatherburn on April 20, 2016

Who hasn’t been frustrated when traffic comes to a standstill or the underground breaks down? Such frustration is a very real human emotion that lets us know that our highways, subways, light rail transit systems etc. are vital for our lives to run smoothly.

Why then have some critical infrastructure industries, such as the energy sector, been better at adopting cybersecurity practices while the transportation sector has been lagging in this area?

The answer, I think, is that never before has the transportation industry been under such pressure to increase capacity and at the same time become more efficient.

Let’s take a look at how, in this challenging environment, passenger rail and public transportation systems can improve their Industrial Control Systems (ICS) security.

Wireless Infrastructure for Train Control Systems
Blog Category: Industrial Ethernet

Posted by: Richard Weatherburn on June 08, 2016

Around the world countries are trying to combat their dependency on oil and reduce their carbon emissions. A key strategy for achieving this in some regions is a focused effort on dramatically improving rail infrastructure.

As a result many rail operators are striving to improve capacity without having to take on expensive and disruptive civil engineering projects. One solution is Communications Based Train Control (CBTC) systems which increase utilization of existing rail infrastructure.

Let’s consider the architecture of CBTC applications and the wireless infrastructure needed to support these train control systems.

Choosing Industrial Ethernet Switches in Space-starved Transportation Systems
Blog Category: Industrial Ethernet

Posted by: Richard Weatherburn on August 31, 2016

Demands on public transportation infrastructure continue to grow as cities expand and sprawl into suburbs. This shift ultimately affects capacity needs (i.e., more passengers) and physical needs (i.e., more roads and rails).

To meet these growing demands, a previously innovation-averse industry has shifted into an era of true pioneering. This has been exciting and rewarding to witness.

However, this escalating demand – coupled with growing expectations for safety and reliability – is creating challenges for the transportation industry. This is especially true for choosing the right networking equipment. Read on to find out about what to consider when evaluating train-to-ground communication systems.
