Footage from Alton Towers theme park in Alton, UK of the tragedy-stricken 'Smiler' ride being tested using crash test dummies late last month.<br /><br />Four people were injured when the rollercoaster crashed in June - with two losing their legs. Alton Towers bosses have reportedly made the controversial decision to re-open the ride at some point and it has been seen being tested while empty and with dummies.<br /><br />The filmer wrote online that "at times there were two cars on track at the same time" when they witnessed the tests.
