1. The train that went nowhere
He never stopped explaining that what he really missed from his howetown was its metro network which had one metroline that only stopped in one station. The train would stay there all the time and people would come in, sit down and get out when the train had arrived which was always. He would use this line frequently with his friends. In the town he lived now, however, people got rather tired of hearing him going on about it.
2. Working the trainstation
He was a unique master-thief, specialized in one very particular trick of the trade. He would sit down in a train station, looking very respectable, and wait until someone would ask him to watch his bags while he was going to the loo, and then steal that person´s bags. Because of the extreme specialisation of his job, he only managed to pull this off succesfully once in his entire life. Well, twice maybe, but the second time they sort of let him do it, out of pity.
