Four locos (numbered E5001 to E5004) were delivered from Kawasaki in 2005 for use in hauling linear-motor powered Ōedo Line trainsets to the Magome Workshops on the Asakusa Line in Ōta, Tokyo for heavy overhaul from 2006, following the completion of the Shiodome Link Line.[1] They are single-ended locomotives which work as permanently coupled pairs.[2]
