No Phil, not equivalent to R2 AFAIK. But TrainLine points near to R2 are available from Glendale Junction;

Not sure if they are 30 or 25 degrees so a call to Brian will clarify as to what angle they are.
You may be able to do as I've done at Quarry Junction though.
It's built on a 90 degree bend, double track, and the points are on the outer track, i.e. R2.
However all the points and track are actually R1. I've re-radiused the R1s to make it fit the space and it works quite well....
