Building of the Birchwood & St. Criox Railroad began in late 2013. As of fall 2015, the layout was maybe about half done. (At least that's what I said in 2015 - in retrospect, probably 1/3 done.) The original plan was to put up a web site after it was all done. But I found so many people interested in observing progress, this web site went online in 2015.

As of late summer 2016, the layout was still not done. But the mountain logging loop did get completed in early August and the logging train ran for the first time for an open house in August 2016.

Track beds and track for the remaining three loops (of the original layout) went down in the summer of 2017. Detail work on the buildings, including wiring LED lighting in many of them, was done over the winter of 2016-2017. The entire original layout was operational for the first time in August 2017.

A significant expansion project which began in 2020 was completed by late summer 2022. The track originally looping the perimeter of the original layout was extended to loop around the perimeter of the entire expanded layout. Two new loops were added in the expansion area. A total of six trains now run simultaneously on the six independent loops. A third mountain and several new buildings were also added.
