It is really great of you to show us the Mystery railroad. It once took us 30 minutes to talk our way into the Forbes Estate to explore the Trinchera Estates and its logging railroad and Steve used some of my data in his book, but I can supply more trivia if any want it about the NG logging line. We mapped it all in the estate, but could not or did not have time to get entry onto the Trinchera Ranch where the logging line ended in the woods to the southwest of the Estates property. I don't think it has even been explored on the Ranch. I have two views of the sawmill off to the west side of the main and the sg spur to the mill went through a notch at Harrell, two curves west of the loop switch. There were other ng track spurs not shown on page 237. It is all on private land so access in not good. For those that don't have Stephen Rasmussen book "The Rio Grande's La Veta Pass Route" should get it before it is out of stock/print.
Best Wished to Doris Osterwald for full and quick recovery from her auto encounter so she can complete a history of this line in a new booklet.
