I am in the planning stage for a medium size layout and have a few questions. I love the look of elevated trains but do not like the added construction time for bench work. I will be using mostly Lionchief loco's so I assume a 2% grade is about maximum, correct? I assume with the R/C aspect of Lionchief loco's that Y's and reverse loops will not require any special electrical wiring. Is this a correct assumption? Thanks for your input.
