14WE (original project names EN57/M and Halny; one unit also called EN61 mainly used for "papal train" excursion services) is an electric multiple unit (EMU) produced by Newag in Nowy Sącz, Poland.

They are essentially heavily reconstructed PKP class EN57 EMU, of early-1960s vintage, reusing only their underframes.

The 14WE is designed for suburban commuter traffic, with the carrying capacity of 192 seats and (nominally) 255 standing places.

It is air conditioned and can be used with platforms 760 to 1,060 mm (30 to 42 in) high.

The trainset has Scharfenberg couplers, which are standard on all Polish EMUs.
