Paddington Bakerloo Line Link

London, United Kingdom - Working as lead designer for London Underground, Arcadis is supporting the £40 million development of a passenger tunnel at Paddington Station to link the existing underground Bakerloo Line with the new Crossrail station.

130m

long pedestrian tunnel

25m

below Paddington station

Approximately 85,000 people use Network Rail’s mainline station at Paddington every day. With the opening of Crossrail, this is set to increase to over 115,000 daily, with as many as 5,000 people per hour interchanging between Paddington and the Bakerloo Line at peak times.

To help ease the flow of passenger numbers, Arcadis led the design of a 130m long new pedestrian tunnel running 25m below the Network Rail concourse. This will offer passengers a smooth interchange between the underground station and Crossrail, without conflicting with other commuters and passengers travelling to Bristol, the West Country and South Wales from the Network Rail concourse.

The subway has been routed to minimize impact on the existing station facilities, with the Arcadis team developing an alternative design solution to the numerous schemes previously investigated by Crossrail. The result is a more cost effective solution for the client, which results in better passenger flow and provides a better end product in terms of the position where the link connects to the Bakerloo Line platform, which is approximately a third of the way down, rather than at one end.

The design of the route has also reduced impact on the Bakerloo Line escalators, with the tunnel passing beneath the lower machine chamber rather than the escalators themselves. The team have been able to mitigate the impact of this by underpinning the chamber from within the tunnel, meaning that the escalators could remain in service throughout the construction and cause far less disruption for commuters.

We are building the Bakerloo Line Link in such a way that no one knows that we are doing it right under their feet.”
