On the redevelopment of Euston station: > Building not just more platforms for HS2, but critically, the extra tunnels for those trains to use shifts intercity services to the HS2 line, releasing lots of capacity in the old tunnels for suburban services. If that doesn’t sound too important, then where’s the UK’s most congested train... it’s the 17:46 out of Euston which carries more than twice the number of passengers that it’s designed for. When completed, HS2 is expected to more than double the number of seats out of Euston station during peak hours. It seems building HS2 is only part of the cost. A lot of it is also paying down "infrastructure debt" that hasn't been touched for decades.
