Making Berlin’s Metro Cars Lightweight

One of the ways to make trains more environmentally friendly – all modes of transport for that matter – is to make them weigh less so that they require less energy to move.

Stadler, the rolling stock manufacturer delivering Berlin’s new metro trains, says it has partnered with lightweight components manufacturer PMC GmbH to help reduce the weight of the fleet. Components such as seats, of which there are many in each unit, are particularly well suited for replacement with lightweight alternatives.

PMC has developed the seats for Stadler. The substantial weight reduction of each seat will make the weight of the entire vehicle significantly less.

Frank Jaeckel, CEO, PMC, said:

“Compared to the typical weight of a seat, the lightweight construction method allows us to save up to 80 percent of the weight. The components still correspond to the highest European fire standards, are durable – more durable than current components.”

Stadler Pankow was awarded a framework contract worth 3 billion euros to deliver 1,500 cars (series JK and J) in 2019. The minimum order is 606 cars. Due to some legal wrangling with Alstom, the order was delayed by a year but delivery will now begin in late 2023.

Franz Ferdinand Protiwa, Head of Engineering, Stadler Germany, said:

“By consistently pursuing the goal of reducing weight we can reduce energy consumption during operations long-term. That's why Stadler cares strongly about the construction of a vehicle that is energy-efficient, and about sustainable acquisition and production. Together with PMC we're adhering to this principle and are installing innovative seating compositions that are being developed and manufactured in Germany with short routes to our site in Berlin.”
