Re: Thanks

Joe,
that seems to be an international technique ... A friend of mine, quite a few years ago in Germany (where I grew up), told me about his youth immediately after World War II. There is a freight bypass, single track, around the center of the city of Hamburg. At a slight incline along that line, boys would grease the track with soap, so the freight train would stall. That allowed the boys to climb the coal cars in the train (not the loco tender) and fill sacks with coal that they could bring home. If they were caught, which happened on occasion, punishment was immediate: loss of the sack to carry the coal in.
Cheers, Jochen
