Scale track and numbered turnouts are readily available from several suppliers. It really is unfortunate for the high railers that Tom Stoltz quit making his turnouts. Highrail numbered turnouts are available from BK Enterprises in Code 148 to match AM track. I understand they will make them with .138 if the purchaser provides the rail. I had one to test before I decided to have mine made elsewhere.
There are more varieties of steam available in S scale but they are limited production and relatively expensive. I expect new designs will continued to be offered. Modern production highrail steam is the Mikado, several varieties of Pacific, a streamlined NYC Hudson, several varieties of Northerns, the Challenger, the Berkshire, the Docksider, and if 1/60th is acceptable the BigBoy. I doubt there will be any new steam engine wheel arrangements in high rail produced and delivered to purchasers in the next 5 years. Hope one of the manufacturers proves me wrong.
