Meitetsu 3150 series  The is a commuter electric multiple unit (EMU) train type operated by the private railway operator Meitetsu in Japan since 2004. Like the four-car 3300 series trains, the 3150 series trains were based on the earlier 300 series trains, which were the first stainless steel body trains to be operated by Meitetsu, although whereas the 300 series trains had long cars with four pairs of sliding doors per side, the 3150 series have long cars and three pairs of sliding doors per side.  , 16 two-car sets were in operation, formed as shown below, with one driving motored ("Mc") car and one non-powered driving trailer ("Tc") car. Passenger accommodation in the early sets consists mostly of transverse seating with some longitudinal bench seats, while sets 3155 onwards have longitudinal seating throughout. The trains were first introduced in 2004. Two new sets, 3167 and 3168, were delivered in April and May 2015 respectively. These sets feature a revised livery.
