No problem Jerry.

Has anyone noticeed, no ones answered Balrog's question?

No, not even close to what I said.  And why don't you let Jward speak for himself?

#1) Off the bat, I stated, I did not know if this was meaningful or if it helped to answer the question, but
#2) That I recalled reading somewhere that said that tankers were not as efficient cars on the railroad as compared to box cars, for the reason that, tankers only deliver their goods to one place and do not return from that one place with a new load; which is unlike boxcars, which can deliver their load and then be reloaded for the return trip.

I have no idea where it comes from or how it can be interpreted that I suggested box cars serve as substitutes for tanker cars.  I also added this was guess on my part.    ?
Yea, I know tanker cars are in operation now, I see them.   

Now I get it-pretty funny! LOL
I like exactly where I am and where the layout currently is thank you.  I like my home and the spot itself.
Maybe someday that will change and me and the layout will be in the same location.

...and Jwad, I never made a suggestion about using box cars in place of tanker cars.  Where did you get that from ?

D-I was going to buy one of those H.F. Dremel knock offs, but then read the on line reviews of them and decided against it.  I am glad I did.
Thank you very much for the tips on the board set up.  The things we learn over time.  The particle board was never my call, and back then, I knew less than I even know now.   
This past year when we added the 4 x 4 plywood sheet, we did it right.  Using the 1 x 3s you mentioned for bracing and frame and 2 x 4s for legs.
We went with 1/2" plywood-much, much better than the particle board.  Of course, back then, I was just happy to have a 4 x 8 space to work with!!

Thank you Joe for the tip on Menards.  Unfortunately, in my part of the country, Menards does not exist.

...and I am fortunate, don't have to contend with a GM.

Not moving D.
I live at one location and my folks live at another.

I understood what the OP was referring to Jward.

I don't know if this means anything or helps you, but I read somewhere that RRs stopped using tanker cars bc they lacked the effecientcy of boxcars.  This was bc with a tanker, there is nothing to put it in for a return trip, unlike reloading a box car with something and sending it back for the return trip that way.  Perhaps this is why you don't see tankers these day Just a guess on my part.

I had figured you and some of the other frequent posters to be steam guys.  Cool!

Yes, I remember the oily spots from fun tack!
And yes, Bin or Zinsser needed as a stain blocker.  Thanks for giving me a few more specifics on what to try should I give it a shot. 
I hear you loud and clear.  Right now, I have the GP35 disasembled (again).  I am cleaning the trucks and gears, wheels and will take the frame apart again to see if I can do any more work on the motor to cut the vibration down.  Also received some new coupler boxes to mount because the old ones were too low.  I think I will try wrapping more electrical tape around the magnet part of the motor to "cushion" it in the frame and see what happens from there.  For $25 I hate to just send it to BACHMANN, just to possibly get it back "cured" which does not turn out to be a cure at all.

Agree!
It actually has worked pretty well and you are correct, there is an over/under bridge arrangement I have laid out with the assistance of my son, who suggested I put 2 AHM trestle bridges together (remember that incline I mentioned with regard to my Bachmann FTA?)  It was a great idea he had.
I have one track that is part of the main run, go under one trestle.  the other trestle has a "spur" #4 switch that runs under it and branches to 2 straight lines with lighted bumpers to hold cars.
For better or for worse, it is my father who dictated the size, bc it is actually in his basement (my house is a raised ranch with a finished basement and does not have the room for a layout.)   I do have a "test track" on a board I have on my bar that I use for working on locos and cars,  My dad would only permit adding a 4 x 4 board to the existing (which was the original layout)  4 x 8 sheet.  Problem is, the original 4 x 8 sheet is particle board (a poor choice in the end) and has warped over time and there are spots you can see the track has dipped here and there.  I was contemplating replacing the original board with either another 4 x 8 sheet of plywood this time or maybe even a 5 x 8?
I still use brass snap track.  I had not been a problem for me.  Plus, I have enough of it, it is not problem when I need to custom cut a piece to fit.  Had been using a hacksaw for this, but got a DREMEL for X-mas, which may work better to do that, among other uses.   

Thanks for the tip boys on the lumber yard. 
Have not been to an actual lumber yard in a long, long time.  Find myself mostly in Home Depot or Lowes.  Don't recall seeing 5 x 8 sheets of plywood there, but I admit was not looking at the time.  Right now, I  have an 8 x 8 "L" shaped layout which is 4ft wide at the 2 ends of the L.     

...and D-just want to clarify again, that the motor itself, does have increased vibration, with higher RPMs, but don't know why.  I do know it does this, bc like I pointed out to "Stephen", when I have take the motor out of the frame and run it on it's own, it vibrates with increased RPMs.

Have you ever used the goo trick you suggested?

Looked in both Home Depot and Walfart last night for goo.  Not sure if kitchen/ bath silicone will do the trick or not.  When I was in H.D., the person suggested I use stuff that looks like blue putty, like "fun tack" used to look like.

Thank you again D for the suggestion AND the kind words.
