What, you might ask is the connection between Perivale Park and the Colne Valley viaduct?The viaduct is part of the HS2 rail link from London to Birmingham – and possibly beyond – and will be 3.4 km long, the longest railway viaduct in the UK. East of the viaduct a tunnel is being bored by TBMs Caroline and Sushila from Northolt to Greenford, ending just up the road from the park at Green Park way. Two more TBMs will head towards Greenford from Old Oak common, a new interchange station expected to be one of the busiest in the UK.
We have been visiting the route of the viaduct as it passes over the London Loop, where the railway will arise out of the tunnel and cross the lakes in that region, for some two years now and finally sections of the trackway are now in place. Watch for occasional updates.
