The Institute of Directors (IoD) has said that a central part of the Government's current economic case for HS2 was that time spent on a train is unproductive.
However, the IoD said its recent research showed that this assumption was "wildly inaccurate", as only 6% of directors say they never work on a train. According to the figures:
- 48% of members say they spend at least half of the journey working
- 26% work for between a quarter and half the time
- 21% spend up to a quarter of the journey time working productively
