A Digital Twin – a circular economy business tool for Public Transport planners and operators
Public transport as such in general significantly helps to lower emissions yet it is still resource- and waste-intensive in itself. One solution to reduce its ecological footprint is to develop and implement innovative circular economy business models. Such models provide valuable guidance for public transport planners and operators on how […]
Predictive maintenance for infrastructure digital optimization in Leipzig
Within CE4CE project Leipzig Transport Company (LVB), together with Kruch Railway Innovations and ATB MOBILITY S.P.A (ATB), a public transport provider from Bergamo, Italy, are developing and implementing a systemic solution in order to introduce predictive maintenance to infrastructure in Leipzig, one of the fastest growing German cities and thus […]
Gdynia trolleybuses running on electricity generated from a solar power plant and fed directly to the overhead wired infrastructure
In 2017 the trolleybus transport operator PKT from the city of Gdynia, north of Poland on the Baltic Sea Coast, made plans and applied for co-financing of a breakthrough investment to install a photovoltaic plant on the roofed spaces of the trolleybus depot with an aim to feed solar energy […]
25kW DC/DC Charger Module for Connecting EV Chargers to Traction Grids
Based on years of experience PRE has developed a standard 30kW Modular Isolated Power Concept designed for multiple charging posts. What is important is that the input of the module can tolerate the severe voltage drops seen in a traction grid, by operating between 400 – 900V, with no defects […]
A simple method for sizing and estimating the performance of PV systems in trolleybus grids
Solar PV systems have recently become the option for the sustainable supply of urban electric transport networks such as trams and trolleybus grids. However, no consensus exists yet on the placement or size of PV systems at the traction substations, and no method is available for easy estimation of the […]
Description Amsterdam’s GVB Charging Buses from the Metro Third Rail
GVB, the public transport operator of Dutch capital of Amsterdam, has completed a study and moved into a piloting phase of a new charging infrastructure for its electric buses. The pilot refers to the four bus lines which serve the northern area of Amsterdam, Amsterdam Noord. GVB’s plans for installing […]
The role of sensors and predictive maintenance for digital optimization and improving the efficiency of public transport in Bergamo
The role of sensors and predictive maintenance for digital optimization and improving the efficiency of public transport in Bergamo Public transport systems are vital for urban mobility, but their efficiency and sustainability require constant improvement. In densely populated urban centers like Bergamo in the alpine Lombardy region of northern Italy, […]
Study on Shared PV System Between Residential and Traction Grids
Previous works in the literature have proven that, at best, bout 40% of the energy generated by a solar PV system is used by the traction grid it is connected to. This is because of the severe generation and load mismatch caused by the transport timetables which mean that there […]
Dutch Trams running on solar power transported directly to the overhead lines
Strukton created a unique connection between the eco solar park ‘t Oor in The Hague (NL) and the power grid of regional operator HTM. This allows tram lines 3 and 4 to run on solar power. There are 4,700 solar panels installed, producing over 1.4 Gigawatt hours per year for […]
Arnhem Extends its Trolleygrid to Intercity Transport by Trolley2.0 Buses
Trolleybus line 352 is an express In Motion Charged (IMC) trolleybus service that runs between the Dutch cities of Arnhem and Wageningen. Arnhem has introduced the new IMC t-buses that can use the existing trolleygrid catenary to charge the t-bus batteries. This means that these state-of-the-art vehicles can be disconnected […]
An Electric Vehicle Charger Directly Connected to the Trolleygrid
Public transport infrastructure have the potential to cater to far more loads than only their own vehicles. One example of this is the feeding of electric vehicle chargers (EV chargers). Coupling EV chargers to the existing transport grid reduces the need for a separate infrastructure, which translates to lower costs […]
