@ScoutingDad posted:This has come a long way since April. WOW !!! Kind of curious about the middle level and the turnout arrangement. Some of those look a lot less than 072 dia - 042 dia according to the list?. I would love to put this on SCARM and run the train simulator to get an idea on how the trains would flow. You are lucky to have a craftsman like @Mike0289 draw up this plan. Nice idea having the main avoiding the smaller curved mid level in order to access the loco facility. And great use of the transfer table. Jeff
You're right, Jeff. The secondary mainline is tighter with an 042 minimum. @jhl1963 shared all the specifics in his post earlier in this thread
