Thanks for finding this site full of weird paper models!!
You need get the password on the intro page for each model to open the PDF files (It is next to the kana for password : パスワード ).
While clicking around the site I stumbled across this link which leads to a ton of train models.
http://vayashis11.com/blog/train/page/1
and more clicking led to more trains

There are many more pages of train engines and passenger cars.

And a trigger warning:
CATS ( 邪悪な猫, Jaakuna neko, evil cat-like things including this one: http://vayashis11.com/blog/train/post-376.html)
Yokai (妖怪) (Strange otherworldly things, https://hyakumonogatari.com/2012/10/26/what-does-yokai-mean-in-english/)
Ghosts (幽霊 Yūrei)
Demons (鬼 Oni )
Trains (Train paper model collectors at risk of finger RSI from repetitive tab clicking )
