Greg has it pretty much right, except for the part about the rail line stating 26 miles east of Machens. Actually the MKT ended at the junction with the CB&Q (Burlington) railroad (now the BNSF) at Matchens. The Burlington line ran North-South between St. Louis and Burlington, IA. The Katy must have had trackage rights via the Burlington into St. Louis, 26 miles away.
