In their 2023 Big Book (http://catalogs.lionel.com/2023/BB/#), Lionel added a 3" straight section (part # 2325030) to the O gauge Fastrack system (page 219). Can this new section get added to the Fastrack library?
Sure, it'll be added in the next update.
The part was added in update 6.50.2.
Thanks, David!
