With regard to the name, the name Derren Brown's Ghost Train is a weird one, because while I can't think of anything better, I would argue that it is a little bit of a misnomer.
In my mind, "ghost train" conjures up images of a spooky tracked dark ride, perhaps slightly old-fashioned, with various monsters jumping out of its crevices. Derren Brown's Ghost Train is not that; the connotations of the term "ghost train" arguably don't match up with the experience provided on Derren Brown's Ghost Train.
Even if you examine the term "ghost train" in the most literal sense (a train with ghosts), I'd argue that Derren Brown's Ghost Train doesn't entirely live up to those connotations. Even though the ride technically takes place on a hanging Victorian train carriage, there are no "ghosts" on the ride per se, from what I gather. The premise of the actual ride itself revolves more around trying to escape a dangerous gas on a modern London Underground carriage.
That does lead me on to suggest that one of the ride's key flaws could be that it arguably suffers from a bit of an identity crisis. The exterior of the ride lends itself to a Victorian theme, the pre-show lends itself to a Derren Brown experiment, the hanging train carriage goes back to the Victorian train theme, but the ride itself is a modern London Underground ride. It's a little hard to tell what it wants to be.
