Well, s this forum shows, lots of different ways to achieve the same result. What is missing from most books, is the time it takes to practice getting good results from their method. It obviously isn't good seeing in print " after 3 weeks and 50 ruined models"....That is a statement with which I totally agree. My pet peeve, are the '5 minute wonders' that think they have solved all the issues, and rush into print. In my opinion, it takes probably 10 years to get a railway into shape suitable for bragging about. I know, I certainly cringe when looking back at some of the work I posted, in haste, on some of the on line forums (not this one).
