N guage code 55 track

Can you join code 55 and code 80 atlas track together

You can, but you will need to place a piece of styrene or similar to help with the height difference, as well as the rail joiners will need to be adjusted, I would think the code 80 joiner can be modified, I know that ME make some code 55 to 80 joiners. You may want to check Walthers web site.

I would take a code 80 joiner and slip on the code 80 track and then take a smooth-jawed pair of pliers and sma***he other end of the joiner making a compromise joint.
Then solder the code 55 rail on to the smashed portion of the joiner.
I did this with code 70 to 55 track and it worked great.
Good luck,

If you want the look of code 55 (close anyway) without the hassle, use Peco code 55. It is a cleverly designed code 80 that looks small. It is also more robust than real code 55.

His question was on Atlas 55/80 joining. Also, I take offense to the statement that Peco 55 is more robust. I use Atlas 55 and have used Peco, for the looks and american feel of Atlas vs Peco’s European look, Atlas is much more in line with the US tie look. Though ME is even better in those areas. As for robust, I have all my track in place, 30+ turnouts and 1800+ feet of flex track and didn’t destroy any track, all my engines and cars run fine. The only problem with Atals is the tie plates are a little tall and in turn you need to use low profile wheel sets if using Micro Train trucks.
