#ukmfg #rail #locomotives #engineering @siemensindustry The first two of 35 six-car Siemens Inspiro metro trains have entered passenger service in Warsaw, Poland. Inspiro is a new generation of metro train designed for Siemens by BMW’s US subsidiary Designworks.
The trains have four sets of doors on each side plus full-width inter-car gangways and are free of interior equipment cabinets. Each can accommodate up to 1,500 passengers, with seats for 244.
To reduce weight, the car body is made of aluminium, and there is a new type of cork-aluminium floor that weighs 30% less than a conventional floor (and also helps to dampen noise and improve heat insulation). In addition, the air ducts are made of textile rather than metal. Siemens says that 94.8% of the materials used on Inspiro trains can be
recycled.
Each train has four power cars and two trailers, while each power car has four asynchronous traction motors.
