London Liverpool Street is still closed due to overrun of engineering
works - and looks like it will remain closed for some time:

"Sorry! Some problems have arisen with the complex engineering work
being carried out over the 10 day Christmas and New Year period.

As a result all services will be severly disrupted this morning -
Wednesday 2nd January 2008.

We and Network Rail are doing everything possible to ensure that
services return to normal as soon as possible, but at the moment it is
not possible to be precise about the effect on individual services.

We do advise not to travel into London if your journey is not
important."
