Superelevation

[Anonymous]

What do you all recommend for amount and procedure for superelevation? My layout has 20" minimum mainline radius, but at one point I have a "photographer's curve" with a calculated radius of 95".

I used a tie from flex track slipped 90 degrees from the way they run on the track under the outer edge. It disappears with ballasting and I think if you are going to do it it needs to be overdone to be seen. Worked for me.

Peter;

The above is a fine suggestion, AND remember to put a nice easement into the superelevated part. Shim (pastic or metal) stock works well for this.

Take the masking tape.. Put a strip down from one end of curve (Under where the outside rail will go) to the other... Then pull a shorter strip and overlay the longer strip but ensure about 2 inches shorter on either end... Then take a still shorter strip lay it down on top and keep it up until you think that you have a decent elevation.

I think the superevelation (Whew!) should begin before the curve and level off about halfway to midpoint. Once the track is past the midpoint and halfway to the end point, you can go and decrease the elevation to 0 degrees beyond the curve.

Hope this idea helps.
