Was it actually built, then? I went on an official visit which included a
ride on most of the system, and the trains stopped in the middle of nowhere,
as the station stop was programmed in to the computer.

IIRC our guide explained that this was due to plans for the station having
been put on hold, rather than it having been removed.

Yes, it was built, complete with signs. The Development got the go-
ahead just before the DLR opened, so it was decided not to open the
station, as it the whole area would be a building site. As you
correctly remember, the trains still stopped at the site for a long
time afterwards, but I think the system was eventually re-programmed
to remove the stop.

The original station was dismantled either just before, or just after
the system opened, I can't remember which. The parts of the station
were stored on some land nearby, and I think some of them may have
been re-used when other stations wre lengthened, but I'm not sure.
