By Scott,
Iwire (may I call you Bob? - makes more friendly this way),
Hope this thread covered the topic enough and helped explain the system.
I am not the best for describing things in a simple or concise way, so if you have more questions now than before, feel free to let me know.
Scott
Of course you can call me Bob I agree it is more friendly.
Yes I learned a lot from this thread, and as far as being concise I suffer from that too, many times I have to cut my replies by 50% before I post them.

I have been looking at your train pictures a little at a time (dial-up) do you have any shots of the controls and machinery.
Talk to you later, Bob
