Totally agree with Roland. You don't know if they are only reserved for part
of a journey

You do, because they say so.

Yes, I think they do.

or if they are a no show. Also very hard to read from any
angle. It was a good idea to have an electronic system for labour saving
maybe but this implementation is abysmal.

The problem with it is that it's an IT system designed and built in the
late 1990s, and so is 20 years out of date.

When I was at Heathrow T2 last week I was surprised to see that there
was a CCTV camera for *every* space in the car park. One of the side
effects (although they could do it with less intrusive technology) was
that empty spaces had a green light above them, so you could see from
afar, down each aisle, whether or not there was somewhere to park.

Trains could have some system linked to checking if a seat was occupied
(although their are issues if people put bags on seats) and have
coloured lights above indicating (eg) Green for empty, Orange for
empty-but reserved, and nothing for occupied. Or maybe red for occupied
and in the foreseeable future a reservation pending.
