With the EN57, PIKO fulfils another wish of Polish model railway enthusiasts. The distinctive features of the original have been reproduced exactly. These include the roof equipment, filigree pantographs, the realistically reproduced lamps, as well as the reproduced interior. The paintwork and printing are appropriate for the era. The close couplings also allow the model to run in double traction, the formation of complete train sets is possible in prototypical manner. A powerful motor with flywheel mass gives the model excellent driving characteristics. Digital operation is already prepared by means of a PluX22 plug-in interface.
