As well as 3 kV DC for operation in Poland, the Pendolinos are equipped with 15 kV 16·7 Hz and 25 kV 50 Hz and the train control systems needed to run in Germany, Austria and the Czech Republic. However, certification for international operation is not seen as a priority, as the trains are restricted to domestic services for an initial 10 years under the terms of a grant from the EU Cohesion Fund which covered 22% of the project cost.
Alstom expects to employ around 130 people at the Grochów depot, which has three covered tracks for servicing and two for maintenance. The company is using its TrainTracer health monitoring and diagnostics systems to manage the fleet, ensuring that sufficient trainsets are available for the operator. Some sets are stabled overnight at the outer termini, and cycled through the depot as required. The fleet management and pit-stop maintenance regime has been developed using experience in maintaining the Virgin West Coast Pendolino fleet in the UK, with many staff being trained in Manchester.
