An integral piece of infrastructure for the London Underground has been finished as part of the HS2 Euston redevelopment
As part of the preparations for the new HSE station at Euston, the existing Traction Substation (TSS) serving the Northern line needs to be relocated.
The new Euston TSS will enable the relocation of equipment needed for ventilation which is required for the safe operation of the Northern line.
MDJV, the construction partner for HS2 at Euston, completed a three-week concrete pouring operation at the end of May to create the external walls of the building.
The HS2 Euston development was a large-scale operation
80 kilometers of steel reinforcement bars, equivalent to the distance between London and Brighton, were installed. 600 cubic meters of concrete were poured, ensuring construction. The interior was then outfitted with blockwork and doors, followed by the roof installation.
MDJV excavated a 20-meter-deep box and a 90-meter-long tunnel connecting the new, highly secure Traction Substation (TSS) to the London Underground network. To minimise noise disruption in the area, the team built an acoustic shed to block out construction noise/
Throughout the project, the existing London Underground substation remained in use, even during the tunnel connection phase. The project was completed without any major incidents.
“The Euston team have worked around the clock to complete the first above-ground structure required for HS2’s Euston station. Whilst the station design is under review, the Government is committed to bringing HS2 to Euston, and we are continuing with the work required to make that happen,” said Andy Swift, project client for Euston Station.
Euston’s old TSS will be preserved and used for a heritage display
The mechanical, electrical, and plumbing (MEP) and architectural fitting for the TSS is now underway and is due for completion by 2025. Once the new infrastructure is operational, the old equipment in the existing TSS on Melton Street will be decommissioned, and the building will be demolished.
HS2 will preserve some of the iconic historical features of the original TSS and tiles will be reused for a heritage display.
Euston will become HS2’s primary southern terminus in London. Earlier this year, it was announced that construction of the new station would be temporarily halted to ensure efficient and cost-effective delivery.
