Ben Gummer is proposing that every tax payer receives a statement of how their taxes are spent.
On Conservative home there is an example of how this might look for a taxpayer on £26,000 pa.
Transport costs are given as below:
The 2010-11 figure for railways is £3 lower than in 2009-10.
UPDATE: This from Ithuriel...
So that's 1.2% of income tax.
Say £4.5 billion subsidy implies total income tax take of £378 billion.
So about right.
But tax take was down in 2009-10.
