designed to make
journeys more pleasant
and safer for passengers.

summary or the PRORAIL IPB

If travelers it spreads better over the platforms and knows where they can board per train class getting in and out faster and safer. ProRail was looking for an information system to better monitor and manage passenger flows and that is resistant to 'railway conditions'. With a team of experts from Atsence, KITT Engineering, Ngage Media, SIDstudio, Strict, Scope Design developed a maintenance-friendly, modular, intelligent information system that hangs freely above the platforms, so that both train traffic and passengers are not bothered by it.

sensors and actors

An important functional question was the integration of sensors and actuators in the displays with the entry information. The idea is that broadcasting and evacuation, camera surveillance and other new functionalities can be realized in one intelligent infrastructure. For example, with the combination of smoke detectors and cameras, active evacuation information can be shown on the displays, depending on the location of an emergency. With beacons and WiFi, three-point measurement can blind and visually impaired accurately guided to the door location. With IP speakers, you can accurate to three metersbe sent an audio message if, for example, someone is in the safety zone and a train is arriving.

product approach

To a maximum benefit to achieve production costs, economies of scale have been used, due to the mechanics of the IPB to design from a universal and modular 'one size fits all' approach. Hardware-wise this creates a generic solution for the basic functionality that is easy to expand with additional possibilities via Power over Ethernet. The system can be adjusted and adjusted remotely via software.

maintenance friendly

Scope focused on it industrial design of the prototype of the IPB. It was primarily important that the IPB can be maintained quickly and safely. The IPB is therefore designed in such a way that it accessible is from outside the safety zone to prevent trains from running during management and maintenance.

contribution scope design

Scope iteratively designed (partial) solutions for working functions of the IPB in accordance with specific design regulations. So became demonstrated that almost all sensors and actuators on a platform could be integrated into the IPB as functionality. This eventually led to one total concept in which the IPB provides the data and energy infrastructure for a flexible set of actors and sensors. Actors are, for example, loudspeakers for broadcasting and evacuation and sensors are, for example, beacons for positioning, cameras, people-counters and antennas for WiFi, 4G / 5G etc.

Scope focused on the mechanics development, on ergonomics and on the overall aesthetic concept and eventually delivered a package of drawings and a functional prototype in which the various functionalities are integrated. FEM analyzes, component choices, software analysis and infographics were realized by the team.

function separation

At an early stage, Scope has one segregation of duties designed for the different 'sides' of the IPB. On the track side is the blue lamp which indicates to the driver what the desired stop location of the train is, at the top the interface with the built environment for keeping birds and a cable tray. The displays are on the platform side and the sensors and speakers on the bottom. The whole is integrated into one prototype that demonstrates the feasibility of this modular system that is universally applicable and that can withstand 'railway conditions'.


An important part of the cost of a product in a 'railway environment' is determined by the management costs in the form of maintenance and cleaning. When maintenance on the through track (in the A zone) must also include the costs of blocking the track. Through smart design of the entire IPB system, Scope Design has ensured that maintenance can take place in the B zone, so that the timetable does not have to be interrupted.

integrated optimization

Prevention is better than cleaning, that's why we have it small wires integrated on top of the IPB to prevent pollution, because birds sit on top of the IPB. The same housing part, in which the electric wires are incorporated, we use to cover a cable duct, so that the cables are not underground concealed need to be easily accessible.

Modularity sensors

The entire bottom of the IPB is reserved for sensor modules with a fixed grid of 1.5 meters. In a sensor module can accommodate six sensors and one speaker set. This allows sensors or actuators with a multiple of 1.5 meters to be spread across the platform, depending on the requirements functionality. The sensors are placed on slides that slide into the sensor modules. The sensors have a fixed one space envelope and a standardized interface for mounting, allowing them to be placed flexibly. The sensor side consists of an extruded aluminum profile in which sensors can be placed in fixed setup slides.

The core from the ipb - the backbone

The 'backbone' supporting structure that forms the heart of the IPB is a steel one box profile with a length of 10 meters. At first, an aluminum extrusion seemed logical, given the long length and the constant profile of the cross-section. However, it soon became apparent hot-dip galvanized tube made of welded sheet steel, a more attractive alternative, due to the size of the profile and the desired corrosion resistance and the required amount of processing. An estimate of the technical feasibility in the field of tolerances, after welding and galvanizing, is determined with knowledge from the agricultural industry in which Scope is also active. Ultimately, this estimate was validated with a prototype of a 1: 1 hot-dip galvanized backbone. The advantage for the strength / stiffness, for the durability and for the design freedom in the cross-section, this was demonstrated.

The result

The IPB prototype was used in the market demand for a light version, which was ultimately realized at Schiphol by nGage Media and KITT.
