I wanted to do a poll but it doesnt seem I can. What do you prefer? How many mainlines do you like? (for average size layouts; like 4x8 size layouts) I prefer two mainlines (my idea is one for passenger and 1 for freight, this is my dream layout: http://www.thortrains.net/marx/ezho2a.gif This one I believe will suit me perfectly. What do you guys like?
