One former Alton Towers employee explained that the Smiler could have up to five cars moving around the track at once and a "block system" run by sensors prevented two cars entering specific sections at the same time.
Another former staff member said: "The block system should have been clear before another craft is able to enter that section of the ride.
Technically, it should be absolutely impossible for two cars to enter the same block, which is down to sensors run by a computer.
"Only one car at a time is permitted in each block and, at the end of each, there is a section where a train can be stopped if it needs to be," the former worker said.

Paul showed no indication that his position had changed since last week's extended floor speech – not officially a filibuster – and that he would do whatever it took to block the Patriot Act's renewal.

Police were out in force to try to block the demonstrations, and there were sporadic confrontations near Kinshasa University.
By owning your own property, you get a say in planning law too – your objection to that new tower block counts for far more than the indirect, dissipated unease of all the people hunting desperately for somewhere affordable in the vague vicinity of their work.
Word of mouth is your only hope; get people talking about you early on, and by the end of your week they'll be queuing around the block.
Moving on 20 years to December 2011, when Cameron used Britain's veto to block an EU-wide treaty, the Sun greeted the news with a splash headlined "Up Eurs" with a photoshopped picture of "bulldog" Cameron giving a two-fingered salute.
