Huge UK station's bold expansion plans to handle 5,000 passengers every hour

One of the UK's busiest railway stations has unveiled ambitious expansion plans to handle millions of extra passengers over the next three years.

Earlier this month (Thursday, July 3) St Pancras Highspeed and Eurostar penned a letter of intent to expand capacity at St Pancras International - to support growing demand for 'sustainable cross-border travel'. The partnership follows an independent study commissioned last year that explored how the popular station could evolve to meet rising visitor numbers in the future.

According to Rail UK, architecture practice Hawkins\Brown has been appointed to undertake and deliver a detailed design and feasibility study. This will allow the businesses to assess how the station can be reimagined to accommodate more passengers and operate more efficiently.

The expansion will be conducted in three phases, with bold aims for the station to be able to handle a staggering 5,000 passengers per hour by 2028. Phase three will take place in the 2030s, and will explore long-term opportunities to 'drive growth' following the capacity increase - including potentially relocating the arrivals flow to upstairs.

Richard Thorp, chief operating officer at London St. Pancras Highspeed, said the station was 'delighted' to be joining forces with Eurostar to expand its capacity. "With growing passenger demand for international train travel, it is important that St. Pancras International station is future-proofed and optimised to accommodate this," he added.

"With a shared ambition and collaborative approach, we can ensure our iconic station is ready to support this demand. We're looking forward to getting started on a new era of connectivity between London and Europe."

Simon Lejeune of Eurostar also welcomed the news, stating it was 'proud' to be part of plans to better the customer experience and 'reimagine our space for the future'. Describing Eurostar as the 'green gateway to Europe', he added: "As we plan to expand our fleet from the early 2030s and increase services to France, Belgium, the Netherlands, and now Germany and Switzerland, this project will play a vital role in enabling that growth and continuing our seamless and unique customer experience."

The concept design and feasibility study are due to be finished towards the end of the year, when a formal design and construction plan has been developed. At the time of writing, no estimated costs for the project have been released.

The announcement comes shortly after Eurostar's monopoly of the Temple Mills depot site has fallen under close scrutiny - with several competitors showing interest in running similar routes from England to France. A report conducted by the Office of Rail and Road (ORR) earlier this year found there is 'some available capacity' at the depot for more trains to be stabled, serviced and maintained.

The conclusion was well received by Virgin Group, which says it is now 'ready to take up the challenge' of launching high-speed passenger train services through the Channel Tunnel. "The Temple Mills depot is the only facility in the UK which can accommodate European-style trains and claims suggesting it was at capacity have been blocking Virgin from coming to the line," a spokesperson said. "Virgin is therefore very pleased with the outcome and we thank the ORR for commissioning this report, which will now unlock competition on the cross-Channel route for the benefit of all passengers."

French manufacturer Alstom is also eyeing up Temple Mills, after signing an €850 million (around £715 million) contract to provide and maintain 12 of its double-decker trains for a Proxima, a private operator in France - as well as France's state-owned company The Société nationale des chemins de fer français (SNCF).

As previously reported, Chief Executive Henri Poupart-Lafarge says the new fleet could lower fares and increase capacity in the undersea Channel Tunnel. However, it will first need to seek approval from regulators to make sure it adheres to strict Channel Tunnel safety rules.

Meanwhile, Eurostar has already pledged to ramp up its offering as part of a major €2 billion (approximately £1.7bn) investment. Last month, the company announced it would launch afleet of up to 50 trains that will be in service from the early 2030s, operating three new direct routes.
