The track is all new old stock. O54 curves have maybe an hour of run time. O72 curves were never used. I purchased as I was able, but building the layout never came to be. All safely stored in totes, so no years of dust. I’d prefer to sell it all at once, but not everyone needs this much. The switches are factory new. Of course you can inspect everything before committing to purchase. The switches must be purchased as a pair. They're generally around $100 each online, but can be readily found new on eBay for $65, so..
Please check out my locomotive and rolling stock listings which I'll be posting soon. Thank you for looking.
