It also means that more people will default to using HEx when going to/from T4, whereas previously anyone with any sense will have used HC from Paddington and avoided the extra fare and change of train. It will therefore have increased the profits at BAA.
Given the recent groupings of airline alliances at LHR, the demand for an inter-terminal shuttle is, I would think, much lower than for direct service to London.
