traffick boss was tasked with beating up a train company with a train delivery
he went with hairdresser and accountant and (got on to) the train front car and (had stop driving the train) the people driving it.
he was having fun with the train, blowing the whistle, playing with controls, when suddenly traffick boss tripped and stumbled and set the cargo delivery in motion
while traffick boss was holding an injured limb and yelling oppressive selfish statements in pain off the train went, delivering the cargo that traffick boss was tasked with halting
“oh no!” went traffick boss, holding his head with his hands
the train had a mind of its own and whizzed down the tracks at breakneck speeds
