Why don't you make 22" curved rerailers [nickal silver track]
Dear 910.seve,
Because most all layouts can be covered by the 18"R T.R.R or the 9" straight T.R.R.
Anything else you can use Atlas #842 terminal joiners or solder wires to the outside of the rails, or very carefully to the inside of the rails, making sure that it doesn't interfere with the "spacing between the rails", a.k.a "the gauge".
Some will hide the solder joints by soldering on the side of the rail away from the viewer, that is, inside the rail closest to the viewer, outside the rail furthest away from the viewer.
Hope this helps.
What type of layout are you trying to make?
Sincerely,
Joe Satnik
