, the company operates a fleet of 24 two-car 521 series EMU trainsets (48 cars) numbered IR01-IR24. Trains were manufactured by Kinki Sharyo and Kawasaki Heavy Industries and are normally operated as two- or four-car formations.
For operation of the Kanazawa to Kurikawa section from 14 March 2015, five two-car 521 series trainsets - three second-batch sets (10, 14, and 30) were transferred from JR West, and two third-batch sets (55 and 56) were newly built. The two new sets were initially delivered in February 2015 in standard JR West livery but were repainted into the IR Ishikawa Railway livery before entering service.
, the 521 series fleet is as follows.
Three newly built 2-car 521 series trains were acquired in conjunction with JR West introducing 521 series trains on the Nanao Line, as the Nanao Line operates a through service on the IR Ishikawa Railway Line to/from Kanazawa.
These sets were built for JR West but delivered to IR Ishikawa Railway and became set numbers IR06-IR08.
For operation of the Daishà Âji to Kanazawa section, 16 two-car 521 series trains were transferred from JR West. These were numbered IR09-IR24.
