Christian Wolmar has an article in The Standard today critical of the PPP's
and the proposed line closures.

One paragraph caught my attention:

'Already they' (the PPP's) 'have been up to all sorts of tricks, such as
carrying out huge amounts of work on the least-used parts of the network,
such as the Hainault Loop at the eastern end of the Central Line, where it
is easier to work than in the centre'.

What exactly have Metronet been finding to do on the Hainault Loop that
deserves the description 'huge amounts of work' - upgrading to 125mph
running perhaps???
