The two old Trains from Nagano to Myoko-Kogen

Sorry, it‘s again about trains. But when I was a child, I‘ve loved to play with my Japanese PlaRail train system, which is for children between 3 and 9 years.

So sometimes when I am traveling around in Japan, I see trains which I know from my old PlaRail collection (it‘s a huge collection). Most of them are old ancient trains, my grandparents have given them to me as a present around 40 years ago :) Thank you so much for that, Obatchan and Ojichan

Does anyone knows the names of these two trains?
