QUOTE: Originally posted by Modeloldtimer I know you said you have HO. BUT! If you want to have a nice RR in the 4X6 size may I suggest that you check "N" gauge. N gauge now has nearly everything HO has. You should enjoy runing 5 or more locomotives at the same time using DCC in N gauge. A 4X6 size RR in "N" gauge is a nice size. The 4X8 that you mention should be the smallest size for HO unless you just want to make a small yard on the 4X6. For HO main line Cruves you will need a minum of 18" radus track. Passenger or large freight cars will not look nice on 18" radius curve track because of the overhang. Some cars might even rub on turns. Couplers also might give you a problem when using long cars on 18" radus track. However running passenger and large freight cars in N scale on 16" radius is a large radius turn. N gauge locomotives and passenger cars can handle curves on 9" radius track. I use to have a N gauge RR until my eyes told be to go back to HO. If you want a large RR in a small space out check out Z scale. Something to thing about... Good Luck whatever way you go...
