Thanks for all of the info guys.
Based on the great advice you have given me, I am rearranging the layout to avoid the 3 contiguous switches.
The one thing I really HATE, which ruins a model train for me, is having a layout where I have to "tip toe" the train through certain sections, biting my lower lip and holding my breath, just waiting for the grating sound of a derailed truck. When that happens, track is gonna be ripped out somewhere!
Then you are definitely making the right decision. I like to run trains slow, but that is just me. That’s the beauty of our hobby - to each his own!
