I am in the process for Train Operator. they just called me yesterday to go for final processing next week and I want to get ahead of the game. When i first took the test back in 2009, i wanted to do the same thing and tried to find any books available to study for the test without knowing what to expect. I went to a Barnes and Noble bookstore and got a PASSBOOK SERIES TRAIN OPERATOR STUDY GUIDE. I am wondering if this book is good enough to start getting familiar with the job or if it is something that I should avoid
