I just found on the Kato web site that they say to just glue one of the two posts that is molded on the underside of the track and to NOT glue any switches, crossing gates, etc. These should be allowed to float, so that they may adust for inconsistencies due to humidity and temperature on the mounting surface.
I'm thinking maybe to just glue every other track piece at one tab and let every other one float.

I have one of those ‘eastern basements' that goes through humidity changes with the seasons. My Atlas code 80 flex track is nailed through cork roadbed to a plywood base (although in hindsight I should have glued it - the nail heads look poor). I did leave a couple of expansion joints on straight-aways. No issues at all so far. The track work has been flawless since it was laid over four years ago. One extra thing I did was to prime all my bench work (every area front, back, and underneath). I'm convinced that this made a big difference in sealing it from the humidity so it won't swell. A dehumidifier helps too.
Dave - is this the same layout you bring to shows? If so, perhaps moving it around is behind the issues you're dealing with?
This particular layout has only been to one show. It was cold and dry that weekend, so I doubt there was much issue. I'm convinced the problem is my lack of expansion joints and the fact that the foam roadbed has so much give (the flextrack can stretch it as it tries to straighten out).
I'm replacing the tunnel curve with Kato Unitrack. I'll solder the Unitrack to the Atlas where they connect, to reduce movement, but I'm leaving the Unitrack sections just snapped together. I'm starting the Unitrack a few inches outside the tunnel portral. It's Code 80, but the ties are a little farther apart. I hope that ballast and weathering hides this. So far the end I did looks decent.
For the other curves I resoaked the ballast and used T-pins to hold the correct curvature. Then I re-soaked the ballast with a much stronger dilluted glue mixture. We'll see how that works.
I haven't figured out where I want to cut expansion joints yet.
Thanks for the suggestions so far!

If you do that, make sure you stagger them. It'll help the rails hold the curve better.
For all you N scale buffs I need help.
I just bought one of these for my N scale layout and it has alot of extra parts. Is it supposed to make another kit and I didn't get directions? Here is a link to walthers showin the kit.

OK, the inside curve through the tunnel has been replaced. I used 3 sections of Kato Unitrack and a new piece of Atlas flex.
Starting on the town side, the Unitrack starts about 3" outside of the tunnel portal. With paint, ballast, and weathering it's not immediately apparent that the change is there. That joint is soldered. Inside the tunnel are the three pieces of Unitrack. They're not soldered, but tacked in place with a bit of white glue. Inside the tunnel yet there's a soldered joint between the last piece of Unitrack and Atlas flex. The flex comes out of the tunnel, through its spiral easement, and ends at a non-soldered expansion joint on the straightaway on the stone bridge.
Thank the good Lord I built a decent-sized access panel, or I'd still be blasting out the mountain!
I checked for electrical continuity and that works fine (although it would be nothing to drop a set of feeders if I have problems). I have to wait for the glue and ballast to dry to check for long-wheelbase operation, but everything checked out as I was laying it. Eyeballing it shows no kinks or compound curves. YET. But I think the expansion joint is in just the right spot to absorb flexing without derailing a train. Having it on a straight is the best idea I think.
Although it's always daunting to dig track out of a "completed" layout, it's a small price to pay to eliminate sub-standard operations. I imagine as the seasons change and I move around (next assignment is Kirtland AFB, NM) more problems will pop up. I keep a stock of flextrack and railjoiners just in case!

I've had a lot of people here try to explain the differences--which is better and what not, but the best explanation I've see is on the Dream, Plan, Build Video #1. Had I watched that, I would have bought a single-stage internal-mix airbrush. Instead, I bought a two-stage internal-mix and it took quite a while to figure out how to get a good job out of it.

From my experiance, the key to success when painting anything is to do many light coats. Don't rush your work - rushed work results in paint going on to heavy, runs, hiding of the details.
Use a compressor for constant pressure.
Even some cheap airbrushes can give great results. I used to use one that I got from harbour freight for like 15 bucks. It was a dual action ,internal mix air brush- looked like a Badger copy.
Practice putting paint down lightly on something like cardboard before putting it on a model. Once you master that, then just go for it! You'll be amazed at what you can do.

Hey now you guys are hidding some good info here. Maybe some of these questions should be on the main page?
Is there anyone out there who knows who may carry SP cabeese, not the silver one.
I have been looking for some time and have only found the Concor that I don't realy like. I think the caboose type is C-40-4 bay window.
Or maybe some advice on how to help the two Concor Babeese run better?
Many Thanks.

Hi apartment railer,
Ask 10 people on this and you may get 12 answers. :-)
Here's what I use and have found easy and successful. I bought a Badger off brand. It says Sears but I expect that Badger made it anyway. The Badger model is a 200 NH. It is a bottom feed single action, internal mix airbrush. Check out the Badger web site for it. I like the simplicity of single action and the volume is adjusted by a set screw in the back. I run it at 18 to 25 psi with an old air compressor that my brother gave me. If you need to buy an air compressor I'd recommend that you NOT buy an oil-less unit. They are typically really noisy so get a model that takes oil. You'll also want to make sure it has an air holding tank along with a pressure gauge and water trap. You don't want any water splotching your nice paint job. You can get a compressor like this for around $70 to $80 if you really shop. I recommend using water base paint because it won't attack your plastic models. I use Badger Precise Design Model Flex. It is already thin so does not need to be thinned for an airbrush. Just pour the paint right into your airbrush jar. Then when you're done you can pour what's left right back into your paint jar. This is the simplest method that I have found while still getting great results. Airbrushing can be intimidating but once you get set up and give it a try you'll find that it's not that hard. If you have any problems just post them here and I'll answer as best I can.

Microtrains makes an SP C30-1 caboose. However, they were pretty much gone by the late 60's. The steel cupola caboose ( http://www.4nscale.com/details.asp?p=5114 ) Microtrains makes bears some resemblance to an SP C40-1 or C40-3 ( http://espee.railfan.net/picindex/c-40-3_photos/1061_sp-c-40-3-caboose-todd_osterberg.jpg )steel caboose. However, the windows are oversized for the SP.

Thanks for the thought but the Concor steps and coupler box are metal parts that are one piece with the chassis. I usually do just that.For the mean time I put IM metal wheels and installed the MT couplers but I had to shrink up the box quite a bit.

Thanks for the offer but it looks like I might not be able to make it to the Jeffco train show. I think I'm going to postpone my try at N scale for a little while. I have much yet to do on my HO layout and I would like to wait awhile to see what develops in N sound.
In the meantime I'll keep reading the posts and continue to get all the info I can so I'll be ready to try it with as much knowledge as I can gather.

Rio Grande vs. Santa Fe.....the battle is over but the glory remains!
The new curve on the inside track inside my tunnel is in place. It's exactly 13 and 3/4" radius (thanks to Kato), but I still get a little slippage with my new GP9 on that curve with a healthy load. I'm guessing it's just the engine, not the track. Nevertheless, that kink that was developing is gone. The other kinks are now gone. Combined with the Peco turnout (lost spring) I replaced on Christmas, my track is once again in great shape.
Funny, I took great care laying the track this summer. I think my problems (save for the turnout spring) were a result of laying (and soldering) the track in a hot, humid garage and then moving the layout to a cooler, drier indoor room.
Use expanion joints! Don't go overboard like I did. I hate "slow" or "dead" spots so at first I had soldered every single rail joint. Somehow, I knew better, but did it anyway.
Nevertheless, all is ell for now. The trains run like a swiss watch (except for my new GP9 straining under a load of hoppers and gondolas with plaster-cast loads; it needs a mate to MU with!).
I also built in the garage and soldered all the joints., but I cut staggered gaps int the straights and between turnouts in sidings. They do close up but even with all these gaps the I still get an occasional kink. I glued the track down and it seems the turnouts don't budge and the kinks end up at thair rail joiners mostly.
If I did it again I would paint all the benchwork to seal it but I would still glue all track.
Hmmm, I think I made a mistake.
I have built several layouts in the past 35 years and it seams that each time I build the bench work using a different method. This time I am building a door size table with some extensions and decided to use a method that I haven't done before. This method uses ripped birch plywood for the strip lumber and is glued and nailed together. I basically followed the design principles as described in the World's Greatest Hobby "Building Your First Model Railroad" video. I have seen this technique used in other layouts in MR magazine and thought that I'd give it a try. Anyway, my issues are that since this layout is glued and nailed it is much harder to make changes in the future. With a table that is screwed together I can just unscrew the areas that I want to modify and make the adjustments needed. I am in the process of adding an extension along a wall and have already found that I want to make an adjustment to the main table and can't. The end result of the extension will be the same but I'll have to use different techniques to attach it to the main board. I wish I would have used screws to hold the layout together instead of glue and nails.
Anyway, I was just wondering what table building techniques others have used and what you like and don't like. Anyone care to share?
Major setback in my PRR H10s project. Basically, I trashed the mechanism. I had a DZ123 all soldered in place and everything worked, except the headlight only lit in reverse. So, what did I do? I switched motor leads. Great idea, except that as I soldered the second motor lead, I noticed the solder wasn't flowing from the tinned ip. Why? Oh, I see. The iron was busy melting the motor lead mount instead of the solder. Try as I might to fix it, no go.
These are the times that try men's souls.
Back to eBay. The original Bachmann Spectrum 2-8-0 that gave its life for the cause of the Standard Railroad of the World was $40 on eBay. That's no small wad, but at least I didn't trash a PCM or BLI. I'm bidding again on eBay.
This steam project will be my last. Henceforward, any new acquisitions in motor power will be diesel, barring some spectacular pre-DCC-installed-PRR-steam miracle deal.
In fact, this project is driving me screaming into the arms of my Penn Central/Conrail idea.

That's a bummer Dave. I sure hope you get the one on ebay for a decent price. I gotta hand it to you for taking on such a project. More than I could accomplish. I am enjoying building an N Scale Architect building, the Shue Cement Company though. It is quite a process and taking some time but is coming along great. Hope your next go at your project works out well for you. Keep us posted.
