Well even if the driver was at the other end he still had mirrors and visual references if he wasn't paying attention from one end who's to say he would have from the other.
When it's pitch black outside and your windows are fogged up because of the humidity and you're backing up around a curve after having been given the "all clear" by your superiors to override MAPO and reverse all the way to the MK (or garage) - it's obvious why being in the other end would have made ALL the difference.
Ok, so maybe we've all been given extremely wrong information about the "manager at Perkins" over the last year, but I would also be quick to defend the Pink pilot, although many others like to blame him.
I've never been a monorail pilot, but having ridden in the front many times and having ridden on that stretch of track many times and having a tiny bit of logical thinking ability, I can honestly say that the Purple pilot is being wrongfully thrown under the bus almost more so than the off-site manager.
As others have implied, it REALLY comes down to a series of terribly written SOPs.
Yes, all parties involved still share some blame, like the guy who never really threw the switch but said he did, and the CMs on the platform who weren't carrying their kill switches, and the manager for authorizing the move without having someone actually in the control tower, and the Pink pilot for not knowing he was on the wrong track. But the REAL fault lies in policy.
It should not have been SOP to override the one and only fail-safe system to make a "routine" move. The MAPO anti-collision system would have prevented this accident, but it was policy to override the system for mile-long journeys while driving backwards blindly.
It should not have been SOP to allow an empty control tower for even one second while a switching or MAPO-override was taking place. Dinner break, going home sick - no exceptions.
Everyone on a platform should have a kill switch. Someone should have been required to have a visual on switches before authorizing a move. At least with "real" train systems, there are trackside visual indicators (both with lights and the old fashioned red/green signs) that let you know which way a switch is aimed. WDW doesn't even have that, but it wouldn't have done any good since Pink might as well have been driving with his eyes closed (which is essentially what the situation mimicked).
There is a lot of Monday-morning quarterbacking, and I'm positive Disney has remedied every item I mentioned above. But no amount of new policy can account for human error - which is ultimately what caused the accident.
