Sorry to trouble but does anyone have any information as to what is
going on with the Central Line these days ...?

Having met with various (excuses?) reasons for the grim service right
now (varying from `overrunning engineering works', `signal failure',
`multiple signal failure' and `signalling systems failure') I am
curious as to how the line has ended up running so badly recently, with
constant and continuous delays.

Many thanks to anyone who might be able to shed some light

The new timetable was due to run from last Monday. When it was loaded it
crashed the train control computer. All Central Line trains are driven
automatically by a central control computer (in simple terms).

Operation reverted to the old timetable while a technical assessment has
been made as to the failure, a solution devised and assurance tests
made.

There was an overrun of engineering works at Epping the other morning so
that comment is quite correct.

Prior to last weekend there have been problems with local site computers
at the Eastern end of the line and communications back to the control
centre - these have caused considerable delays but not shut the entire
line as per Monday.

I understand a fix has been diagnosed and an attempt to load the new
timetable will be made for tomorrow morning.

The above info is provided in good faith but carries no guarantee as to
the service quality on Friday!
