Last week I saw the opposite side of the coin on the Amsterdam metro.
Lightening over 2 nights had knackered the 54 Wed morn, and everything
Thurs morn in the central zone (that'd be 5700 for geeks).

The signs? All normal. The end stations rotated as per a normal day
but with no times. The 54 was stopping short northbound in an outer
station but the signs promised a Centraal Station that it would not
reach that day, while shunting back south on the n/b platform.

In other words, LU can handle a crisis better probably due to more
experience sadly. The A'dam GVB could have done with some whiteboards
last week.

That didn't prevent a Heathrow 4 sign promising next train "1 in
7min", train "2 in 7 min" for over 20 minutes last Friday. And as for
the random different clock times in HattonX...
