Hokuriku Main Line train I transferred from Nanao Line was operated by 521 Series, which was first time for me to ride on.
Local trains on Hokuriku Main Line had used to be operated only by the units built in JNR era, the newly-built unit having the body of 223 Series, mainly in service on Tokaido, Sanyo, Kansai Airport, and Seto-ohashi Lines, and the equipment of 683 Series, in service as "Thunderbird", "Shirasagi", and "Hakutaka"(owned by Hokuetsu Express) expresses. This unit had completely replaced 419 Series on March 11th, 2011, and 475 Series and 413 Series withdrew from the operation between Maibara in Shiga Prefecture and Kanazawa in Ishikawa Prefecture.
Transverse seats with reversible backrest was the same as the interior of 223 Series, but switchable doors without chime different.
After Hokuriku Shinkansen's open in 2015 where I travelled and some sets of 521 Series would be alienated by IR Ishikawa Railway and Ainokaze Toyama Railway. I could travel there before the purchase.
