Your tradeoffs note triggered me - the most frustrating thing in business are that half of all problems are caused by people missing that there is a clever third way, and that in itself causes the other half of problems which are due to leaders not making necessary decisions because they don't accept there's a tradeoffs and want a third option.

Not sure where you are getting the Elizabeth Line stuff from. The forecasts where for 200m a year users and it achieved 230m in 2024/25. That's 15% off, fairly close for a major transport scheme. There was a number of scenarios post covid where demand for PT was uncertain that suggested it might be 170m but the project was already nearly finished by them.

a few year out of date but some discussion on the forecast here, there was no major error except that during covid there was rightly a discussion on how transport demand might vary https://tapas.network/el/el-2.php.

“Slate heaps” is immensely satisfying. I might have to start using that in general conversation!
