Considered the best model railroad engineer at the school, he used to win every competition but recently retired for active competition so others could have a chance at winning.

Third discovered that Oscar put the top of Speedy Mite 2000 in his recent layout. The train club knock him out and post warning on newsgroup about him ending his model train career.
