Modern rail travel: Efficiency, safety and comfort

Rail travel is generally regarded as one of the safest forms of travel. Passenger safety and rights are guaranteed throughout the EU and relate to train delays or cancellations, luggage damage or information obligations.

Full responsibility

The contact persons for this are the respective railroad operators, who make every effort to keep the entire railroad infrastructure in top condition so that all passenger and freight transports can be carried out safely and according to plan. This applies to fixed installations such as the track bed, rails, points, signaling systems for road and rail crossings, bridge pullouts, etc., as well as the rolling stock, i.e. traction engines, railcars and passenger and freight wagons.

So when young adventurers on Interrail, equipped with backpacks and trekking shoes, look at the approaching train on the platform with a little heartache and say goodbye to their parents, friends or other loved ones, then the transportation and safety job for the train operator has long since begun.

Safely from 300 to 0 km/h

If spontaneous encounters for train passengers can be acknowledged with a relaxed “Oh, the next train leaves in 20 minutes”, then this is due to tightly timed connections, perfectly maintained routes and efficiently planned maintenance of the rail network. Several trains run on the same track at a safe distance from each other. Sufficient braking distance must therefore be planned for any track problems, and this can be around two to three kilometers for a high-speed train such as the ICE with a speed of 300 km/h under ideal conditions. This value can vary depending on the type of train, load, track condition and weather conditions.

Safe and competitive

The top priority for rail operators is therefore the safety of the people being transported and those working with them. The second priority for rail operators is competitiveness compared to other transportation options. This goes hand in hand with a whole range of imperatives: comfort and positive experiences for passengers on board, reliability of the services offered and cost-conscious infrastructure maintenance.

How do rail passengers become satisfied rail travelers?

Modern passenger rail transport is so much more than just getting people from A to B. And as different as people are, so different are their expectations of this means of transportation:

  • Basic needs:
    Availability of the transportation service, punctuality, reasonable price
  • Security requirements:
    Track safety e.g. intact rail network, transport safety e.g. smooth ride, safety in the passenger compartment, safety at the station
  • Social needs:
    Pleasant travel company, cleanliness, quiet, considerate atmosphere in the passenger compartment, enough space, enough seats
  • Appreciation needs:
    Friendly and solution-oriented passenger management, welcoming atmosphere in the passenger compartment, especially by the passenger attendants
  • Self-development needs:
    Relaxation, inspiration, joy, socializing

Maintenance perfectly in the picture

So if passengers observe track work as they pass by, this is a sign that operators are taking good care of the track, because nobody wants unplanned track problems and the resulting train cancellations. Today, maintenance staff are prepared in advance with images and data from the monitoring system so that all tools, spare parts and skilled workers are ready and the track can be brought back to the network as quickly and as well as possible.

Infrastructure monitoring as a mini-check for rolling stock

In addition to the detailed analysis of the rail network at the monitored points, a rough classification of the rolling stock, i.e. the trains, can also be carried out. If, for example, a very bad wheel runs over a monitored switch, the monitoring system can recommend a specific check to the train operator.

Checking the rolling stock

Reliability, speed and comfort, including low noise and vibration levels, are particularly important for modern passenger rail transport on urban and interurban routes. Reliability, ease of maintenance, speed and a high load capacity are also crucial for freight transportation. Ideally, the rolling stock is therefore also subjected to checks while the train is running, i.e. at speeds of up to 400 km/h, in order to initiate or plan safe journeys and efficient maintenance at certain points.

Drive-by check: Noise, temperature, dimensions and weight

The destination of the safe journey is always clear:

  • all wheels should roll smoothly and safely on the rails,
  • the load – well secured and evenly distributed – should enable high and safe speeds and
  • Overhangs that could damage passing trains or the railroad facilities must be removed as soon as possible.

 

Rolling stock check in detail

  • zentrak Automatic Vehicle Identification uniquely identifies the individual train or train component for the check using radio frequency identification (RFID)
  • The zentrak derailment detection system reliably detects derailed wheels and can provide an early warning.
  • Acoustic sensors check the condition of the wheel bearings, both tapered roller bearings and cylindrical roller bearings, during operation at speeds of up to 160 km/h.
  • The zentrak profile validation system can use laser measurements to detect slipped loads or snagged branches that could damage passing trains or the rail infrastructure.
  • Temperature monitoring of axle bearings, wheel rims and brake discs of moving trains using infrared (Hot Box Detection, Hot Wheel Detection, Cold Wheel Detection and Sliding Wheel Detection) at speeds of up to 450 km/h protects against overheating of components and the resulting hazards.
  • The zentrak flat spot detection system continuously measures each and, as a dynamic track scale, checks for imbalances or overloads at speeds of up to 450 km/h.
  • Impact detection (DED) monitors passing trains for suspended objects that could pose a hazard or damage the infrastructure.
  • Visual monitoring of trains and vehicle components provides valuable additional information for maintenance personnel, for example when a bolt needs to be tightened, a chain needs to be tightened or unauthorized graffiti needs to be removed.
  • And up-to-date environmental data can provide train drivers with advance information about strong crosswinds at bridges and open aisles, for example.

 

Digital Track Management

The “zentrak Asset and Maintenance Management” software turns digital data into real values. Digital Track Management (DTM) proves its worth precisely at the interface between rolling stock or rail infrastructure and maintenance. It supports track operators, suppliers and service providers in efficiently planning maintenance processes with preventive alarms as well as with location, component and image data, documenting them digitally and on the move, and optimizing the life cycle of infrastructure assets recorded in this way.

The management module (zentrak Fleet Condition Monitoring) maintains an overview of the real-time data of the entire fleet. It includes monitoring and alerting in the event of critical events, machine learning algorithms for proactively avoiding failures, reports and software administration. Numerous diagnostic options are then available to rail operators on an individual, optional and scalable basis.

Blog-Summary

Monitoring and diagnostic systems for rail operations are essential in order to meet the current requirements of customers in passenger and freight rail transport. Increase availability and reduce costs: it’s possible with zentrak!
