The team return to Iacon using a stolen mine train and travel underneath the city to infiltrate the central tower. (Early in story development there was to be a subterranean city under Iacon itself.)
In this version of the script Orion Elita and B team up with Starscream from the Decepticon base. (an even earlier version also had Shockwave with them! I know crazy right!)
