Siemens Venturio is a concept intercity and interregional train from Siemens.
The Venturio concept is intended for top speeds between 160 km/h and 250 km/h, train lengths of 3–9 (originally 3–12) cars, and optional active tilting. The design allows for the installation of various kinds of traction equipment, such as 3 kV DC, 15 kV 16.7 Hz AC and 25 kV 50 Hz AC electric, or diesel-electric.
The Venturio concept was developed from the ICE TD high-speed DMUs for Deutsche Bahn, which were produced by a consortium under the leadership of Siemens. The company offered the Venturio in a tender for a second batch of the related ICE T high-speed EMUs, but another bid won in 2002.
In 2002, Siemens and British transport company FirstGroup agreed to develop a replacement for the aging InterCity 125 high-speed DMUs, the Venturio UK. However, Britain's Strategic Rail Authority ordered a halt to the programme. Following the abolition of the SRA, the UK's Department for Transport started the Intercity Express Programme instead, for which Siemens did not offer the Venturio again but submitted a joint bid with Bombardier.
No Venturios have been ordered or produced so far.
