Has anyone had a problem with long sections of c-track buckling when it is hot and separating when it gets cold. On my layout in the garage where the temp was 50deg f cooler this morning than it was last week a 9ft section of track came apart. I didn't have any screws in this section because this summer it had buckled and pulled the screws out. its is only held in place but a curve at one end and a turnout at the other. I trying to figure out if it is caused by the temperature change or is it something else I am missing. Real track dose change its length with the weather but its mostly over very long distances.

DT, deffinitely not you - C-Track does expand and contract.

I have more noticeably observed contraction, and thought maybe the track was still drying out from manufacture. So while temperature is involved I think it is more likely to be humidity related.

It could be your benchwork, too. The lumber in those temperature and humidity extremes could easily expand and contract a quarter inch over eight feet and in all directions at that. Track would do it but not so drastically. Ultimately your best bet is to climate control the garage.

Controlling the humidity would definetly help and having a room which is sealed as much as possible from the rest of the house would also help.

I have insulated the exterior walls of my room before building my layout, also installed a drop ceiling and painted the concrete floor to help minimize the amount of moisture in the room. Lastly I also installed a dehumidifire in the room to control the humidity level, when the dehumidifire runs it also helps keep the room at a constant temperature resulting in not requiring any extra heat source to be installed except for the already installed air vent from the forced air furnace.

Seesh, Matthew, that is amazing. How extensive of a layout do you have? Now I feel really guilty and my layout could be quite vulnerable with an old dehumidifier.

The room is 13 feet by 12 feet and at the time it cost me about $1000 to prepare.

The next room is twice the size but will most likely cost somewhere around 3 to 4 times the amount due to price inscreases.

I have out grown the present room but have to wait before the next room is available for railroad use, that could be a while.

Has anyone had a problem with C track getting brittle with age. I do not have a permanent layout and find the ends of the track break when taking them apart

The first batches from C track had that problem. I encountered this also with my small layout. The last rails I bought don't seem to have that problem.
As far as I can tell, the older batches has no "O" and "B" marks on the underside.
The olders C tracks are always sold at bargain prices on ebay.

Now that's an idea - collecting rooms for MRR ... Cool[}:)]
No trouble with my C-track so far, Darrin ...

My layout 27'x 8' two levels uses C throughout. It's in my basement. I've never had a problem, except for the old first generation C track which was sometimes brittle. I remember when I used M track and had some rust spots. That was a 100 years ago.

That really got me out of the chair, as I have bought some tracks second hand. I never heard this before. But the ones I could identify for sure do have the B and 0 markings. What a relief.

BTW what does the "B" stand for nowadays? Many years ago many of our schematics had the supply voltage named "B+" instead of the actual voltage value. I wonder if the "B" still stands for that. At least it imprinted next to the center track connection tab. And the "0" then being neutral - two outer tracks. Does anybody know?

As far as I can tell, there are 3 generations C track:

1ste — No "B" and "O" marking, with 5 digit part number. Clips on the end often break.
2nd — With "B" and "O" marking, with 5 digit part number. Better quality, confirmed by Märklin.
3rd — With "B" and "O" marking, with 3 digit part number. The 24 prefix from the part number is missing. This is just like the TRIX C track.

I don't know for sure, but I would guess that the expansion/contraction is mainly temperature related. Most kinds of plastic do contract/expand much more with temperature than what many other materials do.

Expansion/contraction of the benchwork could also be a contributing factor. In that case, moisture could be involved. However, wood typically gets dryer during cold periods so the effect would normally be the other way around.

Thanks for the information.
BTW Märklin part numbers on track pieces are not easy to read, sometimes you even need a magnifying glass and light in a certain angle. [:(!]
That surely could be done [size=3]a lot better IMHO.

That's the nice thing about m-track and board.. Screwing m-track to board has the same effect as reinforcing the table with a steel frame.. No expansion problems down here... biggrinbiggrinbiggrin

True!! Can't say I've ever had this problem, what with my layout being M Track.
