This was for years the only published source of information about the railway. Much of the material has been updated since the first edition, and a new chapter has been added to cover the changes from the cut-off date of the first edition and the formal incorporation of the TH&B into CP Rail.
This edition was reviewed in Canadian Railway Modeller in Train 6 Track 5 on page 31. The reviewer was Jim Martin.
In my opinion, the only serious shortcoming to this book is the index, which is not as in-depth as I might hope (but I'm a technical writer by trade, so my expectations are perhaps a bit different than the average railfan...).
