Picked up a REV L TIU at York. Just installed it and while I have not done much testing; with all engineered filters removed from the layout the two engines I've tried so far I'm getting 10's around the layout. With bus wiring on the layout I'm hoping the REV L TIU will eliminate the check track messages.
Anyway while checking out the TIU Manual I noticed it was printed in 2010 and still had the magic light bulb trick for improving signal strength in its pages. Now with a REV L the need for this is eliminated. Question is if a newbe pickes up a new DCS system wouldn't this manual be steering them in the wrong direction? Also there's no mention of the new USB port. MTH update your manuals.
