Siemens Mobility assessed several sites in the United Kingdom before settling on Goole with an intent to build the plant if it were successful in gaining orders for new rolling stock.

In November 2018, the High Court upheld the decision to award the contract to Siemens, but allowed the other train companies to pursue claims for damages.

[4] The company already employs over 4,400 people in the United Kingdom in rail and other transport related roles, with eight purpose–built sites that provide rolling stock care.

[5][note 1] After searching for a suitable site, Siemens acquired some land in Goole, in the East Riding of Yorkshire, stating that on winning orders, they would build a factory there.

Siemens are also an interested party in bidding for other new tube train builds for the Bakerloo, Central and Waterloo & City lines.

At the same time, Siemens stated that their UK rolling stock engineering and commissioning team would move to the site and its Digital Operations Centre will also re-locate there.

[29] In February 2021, a Leeds-base company (GMI), were awarded a £40 million contract for building the factory and installing the 2.8 mi (4.5 km) track connection to the main railway line near Goole.

[31] The factory was officially opened on 3 October 2024 by the Secretary of State for Transport Louise Haigh and the Mayor of London Sadiq Khan.
