  1. loved your track rail height/mass comparisons. Only one question, is Auto World Track not only "identical" to Tomy Track in its plastic aspects, but are they using the same Rails. Rail Height and Rail Mass?? Dont want to buy a bunch of Auto World Track and try to integrate it into my Tomy Layout if it has different magnetic attraction than the Tomy Track. keep up the stellar tech reviews!! – Reggie
