- k-mcgrady 9y ago>> It sure will cost some of the profit All profits are re-invested with TFL so I don't think cost (within reason) would be a major concern.
- FatalLogic 9y agoThey are already using regenerative braking extensively, according to this article https://www.ianvisits.co.uk/blog/2017/06/10/cooling-the-tube-engineering-heat-out-of-the-underground/ https://www.ianvisits.co.uk/blog/2017/06/10/cooling-the-tube...
- lucaspiller 9y ago> It sure will cost some of the profit TfL isn't a private organisation, they are a government body. In 2015/16 only half of their costs were covered by ticket sales and other income (advertising, sponsorships, etc). The rest comes from government funding, so taxes.
- Brakenshire 9y agoThat's actually mostly not true any more. By next year day to day costs will be 100% self-funded, only capital investment will be funded by the state. http://www.mayorwatch.co.uk/govt-funding-changes-will-force-tfl-to-become-self-funding-by-2018/ http://www.mayorwatch.co.uk/govt-funding-changes-will-force-...
