With the move up stairs my train layout, I'm can't use a loop so I'm ether need to put double track with widen ends on each end or single track with sidings and a reverser loop on each end. I'm am using dcc. And wondering on the best reverser to price sence I have a small budget for my trains. The price on them may be the deciding factor on if I do the double or single track. And for those thinking duck under is the way to go. It's not a option with my back. And the span will be to wide for a swing out or lift out. Two doors side by side closet and enter closets 4 foot wide.
