Siemens opened a new technology and innovation centre for rail infrastructure in Chippenham on Friday, putting a £100 million investment into British rail engineering into service on the same day a global technology sell-off pushed its shares down 2.9 percent. Ad-hoc News reported the opening as part of a busy week of corporate announcements from the German industrial group.

The Chippenham site, a €115 million investment by Siemens Mobility, replaces the company's existing factory in the Wiltshire town and will develop and build the next generation of conventional and digital rail signalling and control systems for Britain. Around 800 staff are moving to the new centre, which is built to the highest BREEAM Excellent environmental standard. Siemens has been developing and producing rail technology in Chippenham since 1897, and 50 to 60 percent of the factory's output currently supports signalling projects in the UK.

The opening capped a week of rail orders. On Thursday Siemens reported signalling orders for two metro projects in Taoyuan, Taiwan, the Brown Line and the Green Line extension, which will use its Signaling X technology, including fully automated operation.

Siemens also reported further progress on its share buyback, purchasing roughly 360,000 of its own shares between 26 October and 1 November. A disclosure dated 2 November put the total bought since the programme began on 1 July at around 5.6 million shares.

Investors will not have long to wait for the next test. Siemens publishes fourth-quarter results alongside preliminary figures for fiscal 2026 on 12 November, with the release scheduled for 07:00 CET. Deutsche Bank Research kept its Hold rating on the stock on Friday, with a price target of €270.
