I finally "finished" my standard gauge/1 gauge layout. We all know our layouts are never done, there's always new (vintage) accessory or train or something we need to add. But the footprint is complete, we're not expanding this anymore. It started off as a 4'x6' table and is not roughly 8'x8'. The outer track that my Boucher 2500 is a 87" diameter and the middle loop is a 72" diameter. I think I referred to it in the video as 57", my mistake. The inner trolley loop is a 42" diameter, again, my apologies for calling in a 31" diameter, I guess I had O gauge on the brain. The 1 Gauge loop is the wider diameter track, which is roughly 72". Marklin called it 185cm. The 1 Gauge track is all original Marklin, there is no modern version of this track that I ever located. The good news is this track was well made in the 30's. The bad news is, it's still 90 years old and has seen a better day. Also, all the 1-gauge track I do have, I purchased from a dealer in Germany, it's hard to find in the US.
If you have any questions, please let me know. A special thanks to Kirk over at USA Track LLC, his track is second to none. Also, special thanks to Carey Williams for the advice on track radius for the Boucher, Sergio Sanchez for restoring my Boucher back to running condition and David and Josh Rosenberg for feeding my addiction of Boucher and Marklin :)
