According to figures released under the Freedom of Information Act, in the last financial year the Home Office spent £9,645,550.94 on train travel. This equates to, assuming everyone works every day of the year, to a travel spend of approximately £26,462 each day. In fairness whilst the figure sounds staggering we all know that the railways cost an arm and leg to travel on, especially if you don't buy your ticket 14 years in advance. I wonder if they get a discount though given the Government "technically" owns the track again now?
Meanwhile, the amount the Home Office spent on taxis in the last financial year was £915,332.49. This is approximately £2,500 per day. I guess, seeing as the Home Office got split recently the figure should reduce dramatically during this financially year, we'll just have to wait a year to find out. I bet the odds would be low that they don't!
