The scope of the Project includes the purchase of rolling stock – 12 new five-member electric traction units, training of employees in the field of maintenance and operation of the vehicles purchased and the shock-repair package. The purchased rolling stock will operate connections on the Sochaczew – Warsaw – Celestyn route in the area of the Warsaw Functional Area. All vehicles purchased will fully comply with the Technical Specifications of Interoperability (TSI) – vehicles will also be equipped with ETCS (European Rail Traffic Control System). Vehicles will be adapted for the transport of disabled persons. The newly purchased rolling stock is intended to replace the current EN57 rolling stock, which due to technical constraints is not able to use the technical parameters of the line.
