Barton Balderdash is attempting to gain control of the Elkhorn Valley Railroad by sabotaging their passenger trains which results in drastically increasing their insurance rates. His dirty work consists of cutting the brake line on one of the passenger dining cars, which in turn causes the entire train to lose brake pressure.

Will Modesty find true love on her journey? And is Tizzy really who she says she is? Watch Choo-Choo Chicanery and find out!
