Why did the Chunnel fail?
Costs went 80% over budget for construction, in real terms, and 140% over for financing. Those costs had to be covered and debt had to be serviced during construction, while revenues were still years in the future. Revenues were a fifth of what had been estimated, resulting in the tunnel's first insolvency.
Why is HS2 so expensive?
HS2 was originally envisaged to operate more trains an hour and higher speeds than any comparable high-speed line elsewhere in the world. It has been estimated that this pushed up costs by about 10 per cent.
What has HS2 destroyed?
