Code .100 to .125 transition connectors.

Right of Way makes them

Mr Jay Criswall can help ya out

I have quite a few of these transitions on my modular waterfront switching layout.

That's music to my ears!!

I have had good luck with grinding away a little material from the bottom of the larger rail with a cut off wheel (But using it as a grinder) for the 3/8" or so where it slips into the joiner.  Only takes a few seconds per rail.  Maybe it will at least get you by until the joiners arrive.  I usually solder all by rail joints also, but grinding the larger rail will make it even

American Switch & Signal do nickel-silver transition joint bars. Not 'rail joiners' like the usual Peco or Atlas fishplates; they need soldering in place, but do make for a prototypical-looking join between the two rail codes.

Sundayshunter,

Just an FYI, that's more or less true.  AS&S did but Right-O'-Way purchased the line and the joint bars are produced by ROW now.

Having used the ROW transition joiners, they do not slide, on, they need to be glued or soldered. I glued mine. I do wish that there were slide on joiners made.

If you look to the right of the building, where the two unstained wood ties are, you can see the compromise joint bars. The grey plastic joiners in the middle of the building are the code 100 glue on joiners. I would be a buyer for code 100 nickel silver slide on joiners

If you look to the bottom of this picture, or the right where the unstained ties are, you can see the slide on code 125 rail joiners from ROW. I REALLY love these.

Ah, thanks for the updated info! 

When you need to mix different height rail just lightly solder the traditional slide-on rail joiner onto the larger rail size be careful not to get excess solder into the void.   Then snip a sliver off of a feeler gauge of the correct difference & insert it into the 1/2 empty side of the rail joiner and slide on the smaller rail, solder this side optional.   Keep .023", .025" & .009" feeler gauges handy.  Available individually from your Snap-On dealer.  Not  Right-of-Way but it works fine.
