I developed some track plans that are actually expandable layouts for folks running O/O27 o na budget. Starting with an oval of track, yo ucan expand in increments to some pretty nice-sized pikes, and you won’t have to stop running trains to do it. There are 18 layout systems, and a total of over 80 new layouts. Just go to http;//www.thortrains.net to the O/O27 sectio nand find the “O/O27 on a Budget” link. When you get there, scroll down to the Lyoput link. Enjoy!
