Publisher's Synopsis
Derailed trains, sinister welders, an abandoned warehouse, and a junkyard dog - join Josephine and Francesca Hardy as the twelve-year-old cousins scramble to solve The Mystery of the Derailed Train.
Meet Josephine and Francesca - the Hardy Girls! The year is 1975. Frank and Joe Hardy, once famous teen detectives, are grown up, married, and have become successful orthodontists. The Hardy Boys' youthful sleuthing freed Bayport from crime for twenty years. But now a new generation of criminal is back. The Hardy Girls - twelve-year-old cousins Francesca and Josephine - pick up where their fathers left off. Careening around town on their bicycles, trying desperately to track down the train derailers while staying one step ahead of bumbling Bayport Police Chief Oscar Smuff, the Hardy Girls tackle their second case.
