I'm not up on all the issues with Crossrail, but that trains cost too much in the English speaking world is well known and Crossrail is not exempt. Generally this comes down to stations that are much larger than needed and other things that appear to be justified until you dig deeper and discover they are expensive and the rest of the world does without just fine.

Trains cost to much because like many other countries, Britain buys from their own manufactures. Because of the state of British railroading since privatization most of British rail manufacturing collapsed and only a very small number of manufactures are left.

Station being to large is a question of taste and priorities. Saying that such tradeoffs are not worth it is different then just saying straight up that 'the results are terrible'.
