I dunno man, I think this we've got you beat. Overall for HS2:

The cost:
• 2011: £32.7bn
• 2013: £45bn
• 2015: £55.7bn
• 2019: up to £88bn
• 2020: up to £106bn
• 2026: up to £102.7bn… for a fraction of the original route

What’s been cut along the way:
• 2021: Eastern leg to Leeds: SCRAPPED
• 2022: Golborne link to Scotland: SCRAPPED
• 2023: Birmingham → Manchester leg: SCRAPPED
• 2023: Crewe hub: SCRAPPED
• Euston terminus: paused, downsized from 10 platforms to 6, now needs private finance

Original plan: 11 cities, 340 miles, £32bn, open 2026.

What we’re getting: 4 stations, 140 miles, £100bn+, open 2039.

And then there's an underground tunnel that cost almost 200 million before being cancelled - not a single grain of soil was moved.

1.2 billion has already been spent on an underground tunnel in London just for... consultation? They're nowhere near even starting yet.

If people think our countries aren't corrupt they are deluded
