I had TransDEM but I would have to buy it again to install it again. I no longer have the old install. I emailed Roland a while back. I guess he upgraded it or something. The DEM routes I have are blank routes by fishlipsatwork. As long as the elevations aren't too far off, I could probably use blank baseboards in between. I have a bunch of Amtrak stations by davesnow, and some from an Amtrak site by PerRock, and the Selma, NC station by the late bendorsey. John, I'm going to work on it in sections, like northern Virginia and Lorton to Richmond, then Richmond to Florence, SC, then merge with the fishlips DEM, and merge the two fishlips DEM's together at Charleston, SC, then create more blank baseboards to Jacksonville, FL and finally merge the Jacksonville to Orlando DEM blank route. I think there is a Jacksonville, FL station on the DLS as well. The Auto Train terminal in Florida is in Sanford, FL which is north of Orlando. I think using flat baseboards for parts of the route will keep the file size down and the slowdown to a minimum. It doesn't have to be exactly to scale on the flat baseboards parts. I'm just doing the section from below Washington, DC to Orlando. I found a route from Wash DC to Richmond on the DLS but it's way too short and has a bunch of missing assets which are either payware in payware routes by N3V (RoysTrainz, tume) JR (Wearsprada) or by authors which I have no idea where the assets are, I would have to use kuid index to find them. But, I'm not using that route anyway, I'll build one myself with blank baseboards that's much longer.
