http://www.youtube.com/v/KyhYvsjkCLMThese look incredibly dated to me, not necessarily in a good way, but reading a little bit about this former Seibu rolling stock, some interesting data appears. For one thing, they're old, originally built in late 1969 and early 1970 as 4 4-car sets, 3 by Hitachi and 1 by Seibu themselves. In 1974, Seibu continued, building 2 new intermediate cars for each of those sets and, why the hell not, 2 new full 6-car sets. Perhaps they were just assembling Hitachi-fabricated parts (paging Dr. Bikkuri). The Seibu handywork must have been just fine, as the 2 3-car sets that live on with the Toyama Chiho Railway are more Seibu than Hitachi--4 of the 6 cars are Seibu. Also, the end cars are from the original 1969/1970 construction, not the 1974 run.
Toyama has done some refurbishment of the interior of set #2, which debuted just a few days ago on the 23rd as a sightseeing train. By Mitooka Eiji of JR Kyushu fame, it's not quite as dramatic as some of the renovation that JRK does (Toyama is cloudy, it probably keeps them down) but very nice nonetheless. I'd love to take a ride around in such weather. Images from this thread at Ompuchaneru:
