Just because someone has managed to get high up in management does not mean they are not an absolute idiot who will make stupid decisions. I have worked for and with 'managers' who are morons of the highest order who make continuous bad decisions, but it can take a long time in a large company for the disastrous results of those decisions to show their full effect (which in my own experience has included the collapse of a major highstreet name around me). Short term gain often leads to long term pain.
Having said that, it might be completely financially unviable to continue CCRs operation, there might be outstanding maintenance issues that just can not be resolved within a reasonable budget. But I highly doubt that, I think they have driven the family audience so far away that the cost per passenger to run CCR is too high even though they are just the same costs as they have always been. The decision to completely drive away the families is another issue altogether which a long way down the line I think will come back and bite them on the bum.
What do we think they will do with it? Will they spend money removing the track and the station? No, they will leave them there rotting so to first time visitor guests (which there should be many of next year with The Swarm) will look at it and think "Oh, that's broken. Poor reliability here. Some of this place looks a bit run down, doesn't it".
