Rescue a group of locomotives at night

Hey. Welcome to the first night shift. Recently, a private owner got arrested for theft and piracy, and his company (Electro Diesel Company; reporting mark: EDCX), was shut down as a result of a government issue, and so all of EDCX's assets were liquidated, four diesels were left abandoned in horrid condition, and are at risk of being scrapped. The fifth locomotive in the yard is currently being scrapped and is beyond being saved. So you must get the four unharmed, rusty locomotives out of that abandoned yard now, otherwise they will be destroyed, once they are out of the yard, get them to the headquarters of Locomotive Hunters Inc. as soon as possible. You're doing this for a total of four locomotives tonight! Good luck!
