"One team gets on at one station," one man said. "They blow the coupling and then just get off at the next station. Easy in, easy out. Nobody would suspect a thing."
"Yeah, and the second team unloads the carriage onto a bunch of horses and makes for the coast," another man said. "If Team One blows the coupling at exactly the right time..."
"You really think someone can blow a coupling at exactly the right moment to leave the carriage in the right place?" The objection came from the only woman at the table. "Gary, the Tullup reaches speeds of over three hundred kilometres per hour between some stations. Have you ever heard of a thing called 'momentum'?"
Sounds like the kind of plan that comes with the words "what could possibly go wrong?" attached. Fine times ahead, characters...
