Maya, an academy award winning software was used to create a digital set based on the script. Layouts of the train and characters were made using the software, although the team didn't finalize any locations during the test, they used actual physical proportions of a real train. Once the director approved of the layouts, basic actions of the scene were carried out.

Srinivas along with the director and the director of photography blocked the camera angles for the scene using the software. Each shot had 2 to 3 versions of camera angles made to get a better view of the sequence. With the digital shots in place, temporary clips better known as 'playblasts' were extracted from the software to view the shots they made in real time. With these clips in hand, Anthony - the editor, was required to line up these clips according to the scene. This gave the team some room in improvising the shots that were made. Utilizing this method, the team planned out 40 crucial visual effects scenes of the film.
