Gregg posted:Just a couple of thoughts.... does the read find the tiu? and what kind of track signal do you have where you're trying to add the engine. Do you use a programming or small test track. A programming track can be any track with a good track signal with no other engines receiving power anywhere on the layout. good luck.
Thanks for the comments. Using the "Read" function shows my entire inventory of engines except for the Yellowstone which I cannot seem to get into the system (it was loaded on Saturday; Sunday when the "engine was not on the track", I deleted the engine and then tried to reload it, I got a number of different negative messages and could not load the engine, where I am now).
Track signal is generally in the 9-10 range however there are some small areas that drop low. As I said in the original post, I noted signal changes from 9 down to 6 and then back to 10 within only 6-10" on the same piece of Gargraves; I am hard pressed to understand that.
I don't have a test track but plan to disconnect all channels from the layout, use one block as an effective test track and sequentially connect different channels to it to see if I get different results.
