Our metro for the future
Maximum benefits, optimised comfort, high sustainability – Inspiro
Cost effectiveness
Operating costs account for a substantial part of the overall costs for operators. Thanks to energy efficiency, reduced maintenance costs, and high reliability, the Inspiro helps to reduce expenses. In addition, operators can enjoy benefits with regard to revenue thanks to the high passenger capacity and optimized passenger flow – in short, by making optimal use of the metro system.
Passenger comfort
To a large extent, the vehicle design plays a major role when it comes to passenger comfort. That’s why we paid special attention to this aspect during the development of Inspiro. With its design language, the Inspiro creates an inviting environment in which passengers enjoy their travel time in the metro rather than viewing it as lost time.
Environmental friendliness
Energy efficiency, passenger capacity, and passenger comfort determine how environmentally friendly public transport is. These factors help to reduce the CO2 emissions of the railway vehicle. In addition, the millions of associated individual trips that are saved protect the environment in a number of ways. With a recycling rate of around 95%, the Inspiro is especially environmentally friendly.
Inspiro highlights
Extraordinary design – for the cities of the future
The Inspiro’s modern and distinctive vehicle design is immediately impressive. It was developed in collaboration with Designworks, a BMW Group Company. The exterior with its dynamic front end is striking and makes a lasting impact on a city’s image.
Flexibility – to meet individual needs
With the Inspiro, the platform concept and flexibility are not contradictions: The concept of Inspiro offers many versions and equipment options.
- Train configurations with up to eight cars with varying degrees of motorization up to 100%
- Variable length and width of the carbodies
- Optional longitudinal, transversal, or mixed seating configuration in the passenger area
- Three or four doors per side per car, with outside sliding or sliding-plug door types as options
- Extensive equipment options – from driverless operation (GoA 4) to CO2-controlled air conditioning
Passenger comfort – subway travel that engages all the senses
- A thoughtfully designed interior with wide passageways conveys a generous feeling of space.
- The innovative ambient lighting system with its carefully placed groups of lights creates a pleasant atmosphere not previously seen in metros.
- Instead of the usual grab poles and hand rails, Inspiro offers innovative and distinctive supports in the form of a stylized branched tree: the Lightree®. It allows several passengers to hold on while maintaining a comfortable distance from others.
Energy efficiency – through innovation
The Inspiro’s energy efficiency is based on two factors – its weight-saving design and energy-efficient technologies.
- Reduced overall weight of a single car by more than three tons compared with the previous generation due to the light-weight carbody and a weight-optimized bogie
- State-of-the-art energy-efficient traction technology
- Energy-efficient LED lighting
- Load-regulated, air-quality-controlled air-conditioning system
Optimized capacity – for cities with high transportation needs
Many features of the Inspiro provide improved system capacity to ensure even greater efficiency in operation of the vehicle fleet:
- Electrical and appliance cabinets can be eliminated entirely in the passenger area, creating more space for riders and enabling operators to optimize passenger capacities.
- Large doors 1,400 mm in width make it easier for passengers to board and exit the Inspiro and reduce the amount of time spent at stations.
- The doors can be equipped with easy-to-see light strips. In conjunction with the octagonal door shape, this design helps passengers to orient themselves on the platform while also optimizing passenger flow in stations.
Siemens Mobility metros – past and present
From Berlin, to Budapest, to the world
Siemens Mobility has been a pioneer in electromobility on rails since 1879, and has been building modern, high-performance mass transit systems since 1881.
Whether as trams in dedicated lanes, as elevated trains, or as subways, Siemens Mobility’s technological innovations in rail traffic still stand today as pioneering achievements in the ongoing development of urban mobility worldwide.
