How to Maximize the Lifecycle of Trains, Infrastructure Safely, Efficiently

Reports of passenger rail accidents dot the news cycle, often citing lack of modernized infrastructure as a leading cause. Despite these facts, it is simply not realistic to expect commuter and subway systems to be overhauled overnight. Instead, the goal for transit operators should be to maximize the lifecycle of trains and infrastructure in a safe and efficient way — how can transit agencies maintain and repair infrastructure as it ages in the most efficient way?

One approach that’s been gaining traction lately is digitization. In the rail industry, digitization can be achieved with solutions like GPS technologies and updated rail signaling systems, but these don’t necessarily solve for deteriorating infrastructure. For that, transit agencies are turning to digitized assets, or the act of bringing life to physical objects, such that those objects can communicate directly with operations personnel to facilitate preventative and predictive maintenance, incite a higher level of asset utilization, create better asset visibility and planning, and allow for more accurate reporting.

Making Assets Smart

If an asset is able to “tell its life story” to anyone with a smartphone-based reader, then it is smart. In the world of rail management, this would mean any object that requires maintenance can dictate repair instructions, at the precise moment in time when an action needs to occur. When a railcar, for example, is able to relay real-time detail about where it is in its 30-year maintenance and repair lifecycle, along with compliance criteria that may be required, the game simply changes.

At its core, this kind of approach is a 180-degree turn from traditional means of tracking lifecycle history and actionable needs. Instead of recording notes in an analog logbook that is fundamentally de-coupled from the asset, smart assets can distribute key information — manufacturing details, part specifications, authenticity and progressive maintenance activity — on a product itself, across its entire useful life.

Making Lifecycle Information Efficient for Rail Operations

For rail, maintaining full visibility into the state of capital assets is essential to service availability, increasing passenger safety and achieving optimal lifetime value. Attaching accessible data directly on an asset improves maintenance and operations since maintenance professionals, at the point of interaction with the asset, will be fully informed about the product’s history before undertaking any maintenance procedures.

Compare that to traditional matrices of rail operation, where paper logs might get misplaced or become unreadable, while data that has been uploaded to Enterprise Asset Management (EAM) systems can erode during IT consolidation and upgrade cycles; worse yet, storing critical information in remote locations makes it nearly impossible for operators or third-party maintenance vendors to access at a moment’s notice.

Full visibility also increases safety for passengers and train operators. When parts have the ability to compute and communicate, they are able to signal to maintenance crews when there is an issue, or if a component is due for replacement. Providing maintenance professionals with the most current information possible will limit unnecessary overhauls and repairs to keep trains on the track longer, and heighten the level of safety transit agencies can provide their riders and operators.

Lessons Learned from Aerospace

When advances in inexpensive, rugged semiconductor chips made it possible to attach, or embed data within physical assets, aerospace suppliers became textbook early adopters. Airbus now ships its A350 airliners with thousands of high-memory passive RF tags. This gives them improvements in assembly operations, and provides airline operators with a lifecycle data platform so they can support improved operation and maintenance. Airbus and Boeing are moving toward tagging all serialized, repairable, replaceable and maintainable airplane parts — about 10,000 parts on a typical airframe.

Many aircraft components carry specific, periodic inspection and maintenance requirements in order to be legally airworthy. The smart asset approach improves aircraft operators’ ability to sustain maintenance and inspection records for each component. When components are sent out for repair or overhaul, the configuration and history data on the part becomes instantly available to anyone who touches it, even if the airframe is thousands of miles away.

This same digitization has the potential to transform railway asset management as well, such that rail agencies can record, store, and manipulate critical data and drive major business benefits. It is no wonder 92% of rail industry companies plan to invest in digitizing their business in the next three years, according to the 2017 Rail Supply Digitization study. The trick is getting it right.

Next-Generation Asset Lifecycle Management in Context

In summary, the next-generation of lifecycle operations will allow the entire, granular history of capital assets to easily and inexpensively become part of the equipment itself. This elegant distribution mechanism provides crews with complete origination, usage and maintenance history information, without depending on access to centralized systems, networks or paper records. The model is, in fact, analogous to what happened when computing moved from mainframe systems, to distributed PCs and finally to the mobile device ecosystem that is ubiquitous today.

When assets become imbued with their own computing power, you begin to see the potential for lower lifecycle costs and improved safety. The opportunity to fundamentally transform the asset lifecycle management process in rail is here; it is now up to stakeholders to grab hold.
