Austrian Federal Railways (ÖBB) recently announced signing a significant framework agreement with Siemens Mobility, valued at more than five billion euros. The deal entails the delivery of up to 540 single-deck electric multiple-unit aluminium trains, which are expected to enter service in 2028.
These trains are developed from the manufacturer's Mireo platform, a modular system that boasts low energy consumption and lightweight aluminium construction, making it an environmentally friendly choice. The Mireo platform is designed as a successor to the 'Mainline' variant of Siemens's Desiro EMUs. It can form trainsets between two and seven cars long, and the railcars can achieve a top speed of up to 160 kilometres per hour (99 mph).
