Hello Pappy ... You are in luck ... I am working on two DEM's ( one smaller Fishlipsatwork), (and the other a Jerker DEM, which is hugely huge, and covers a 6 County area).
I will release the smaller Fishlipsatwork route very soon, as I had promised the smaller route to PRRE6 (and others) by June 1st, but I am working very hard to release a WIP Beta TRS2006 CDP ... ASAP ... I will release it in some degree of completion this month ... I Swear ! To all as freeware.
When I release it ... future improvements will be obsoleting all previous CDP's ... and the can be deleted in leu of the new improved CDP's that emerge.
I have no textures, trees nor buildings ... as I am trying to lay interlockings in great detail, and I am tugging up and down on gridwork constantly.
So it will have gray baseboards:
The reason why it is late is that I am working to get AI Trainz working through the interlockings without stopping or creating their own errant paths, or going in reverse.
The present route goes from Altoona to Cresson ... but Cresson to Johnstown is heavily in the works this week.
My love of the Horseshoe goes back to @ 1975, and I first visited there in @ 1962 ... So who's Pappy ... I'll be 55 on the 15th !
That would be a perfect release beta date !
I previously gave this route (a much earler, now obsolete version) to one person a couple months ago, so it is nearing testing for all.
