Okay, Paper Trains is about to the midpoint. All of the models on the bottom shelf will be from the Tweetsie Railroad site,
tweetsie.com/kidz-zone/paper-train/
Top shelf will be nicer models, primarily from Kaukapedia,
www.kaukapedia.com/index.php?title=Bastelbogen:_Oldtimer-Lokomotive
The Adler from
www.olis-bahnwelt.de/basteln/basteln-lok-adler will also be included, and possibly an Australian locomotive.
As the bottom shelf was meant to be 'busy', I printed everything at 73% and did enough to fill things up.
