In the recent past, I have complained when trainboard PA advertises
interchanges that do not exist - mainly due to engineering closures.
While travelling this weekend, 2 District trains reported absence of
Jubilee and Victoria lines at Westminster and Victoria, a southbound
Northern line train reported the Jubilee missing at Moorgate and a
Circle line reported the Victoria outage at Kings Cross St. Pancras.
In each case, the driver made a PA and suppressed the automatic system.

Normal service was restored on a Metropolitan train from Uxbridge which
said nothing about Chiltern interchange at Harrow on the Hill or about
the lack of the Victoria at KXSP. It was notably silent too about 3
several minute platform waits between Eastcote and HOTH.

Oh well, 4 out of 5 is not bad.
