rOgruth,
My lower level tunnels will probably only have walls for the first 8 to 12 inches. The tunnel on the upper level is double tracked and about two feet long on a curve. It will have walls the full length of it as it is in a prominent location. One will be able to lean down and watch the train comming around the bend with the headlight glowing.

The other tunnel portal will be located at the bottom of the photo. You can see one at the top of the photo. You will just slightly be able to see out the other end. I am also putting a roof on the tunnel. That way the steam locomotives will be able to fill the tunnel with smoke like the real thing!

I have been doing a little more work on the layout the last couple of days. I have started building my tunnel first and then the mountain over it. Kind of backwards from the prototype, LOL. The mountain came first and then the tunnel in the real world. I want my tunnels to be lined. In my opiniom nothing ruins a nice mountain more than a tunnel that shows that the mountain is hollow when you look into a tunnel portal.

I had always wanted an A-B-A set of Baldwin RF-16 Sharks. Especially in the Pennsy freight colors. Now I am kicking around the thought of picking up another B unit! I think an A-B-B-A lash-up would look impressive!!!

3rail,
Thank you for your reply. The change in cab numbers is good to hear. Any idea if the Pennsy Alco FAs will have new numbers? I bought mine about 5 years ago. Would like to get another set, with different cab numbers on both.

3rail,
Just a question for you. I just finished running trains on my layout a few minutes ago. I have a double track upper level mainline and a single track line on my lower level. Anyhow, on the upper level I am runnig two sets of Williams by Bachmann diesel freight trains.  One has a set of A-A Pennsy Alco FAs and the other a set of A-B-A Pennsy Sharks. Here is my question for you: Would it be possible to change cab numbers on a set of diesels that you plan on running for 4 consecutive years? For instance, the NYC GP30s are currently numbered 6121. If you were planning to have them cataloged for four consecutive years, could you change the cab number after two years to say, 6124 or something? That way those of us who want a new cab number could have it and those who are just buying a NYC GP30 and are unconcerned about the cab number and only buying one, would still buy one. I was thinking as I was runnig my trains about how much I would like to have another set of Alcos. this time, A-B-As and with different cab numbers than the set I am running.

The arch under bridges are from Lionel. I have four of them on the layout.

Here is an aerial view of my layout.

3rail,
Thank you for the info on the new GP-30 diesel locomotives. The lockout switch is a great feature. That is how I usually run two powered "brand L" locos, I lock atleast one of them out in forward.

Thanks Joe!

I copied and saved your reply!

ANTICIPATING!!!
   Thank you, Mr. Bach-man.
We all can't wait to see what each year will bring!
Cobrabob.

Mr. Bach-man,
When can we expect to see the 2013 Catalog?
Either On-line or an actual paper copy?
Cobrabob.

Of the last eight locomotives which I have purchased, six are Williams! Two Lionels.

671,
Thanks for the tip.
Cobrabob.
By the way. I bought my Pennsy Alco Fas a few years back and I love them. They were my first Williams/ Williams by Bachmann locomotive purchase.

#rail,
Is it possible to make it so that a second GP-30 unit will always start in reverse so that I can run them back to back rather than "elephant style"?
Cobrabob.

Mr. Bach-man or 3rd Rail,
I was just wondering, any chance for non-powered dummy unit GP-30 diesel locomotives for those of us who wish to run multiple unit lash-ups? Purchasing two or three powered units is a bit costly for some of us. And I really like to run my road locos in multiple unit lash-ups! What do you think? Perhaps you could even package a powered and dummy unit together as is done with the F3s, FAs and PAs. I know a few years back brand "L" packaged three GP-9s together as a set, that would be great too! The locos could all have different cab numbers.
    Would anyone else out there be interested in GP-30 powered and non-powered locomotives? The new GP-30 is a nice piece with great detail. A non-powered NYC GP-30 would really make my day! A powered and dummy set of of PRR and B&O GP-30s would be nice.
Cobrabob.


As you can see, here are my Williams by Bachmann Alco FAs and Baldwin RF-16 Sharknose A-B-As.

I have also requested Nickel Plate Road GP9's!  PLEASE, Mr. Bach-man!!!!
Cobrabob.
2013 would be a great year for it!
