Transcisco Tours purchased BN 6635 and 6642, and later Doyle McCormack's 743, for excursions. They became MCHX 1001-1003, and were painted in red and blue with grey & black pinstripes. Transisco installed HEP generators to power the passenger cars. After plans fell through, Wisconsin Southern purchased them in January 1992 and applied their red and silver colors. The units proved too heavy for regular service, although they were used for special events and leased to the BN from October 1993 to April 1994.
