THIS MONTH Polish rolling stock builder Fabryka Pojazdów Szynowych will complete the last of a batch of 10 Type 305Ad sleeping cars ordered by PKP, the first six of which entered service in June on the Jan Kiepura Brussels - Warszawa service.

Built to UIC 505-1 clearances, the carriages are designed for domestic and international operation on standard-gauge routes. Accommodation is provided for 28 people, in two A-class and eight 2/1-class compartments. The A-class compartments have two beds which fold to form seats separated by a table, and include a toilet compartment with shower (below right), a wardrobe and DVD player with LCD screen.

The 2/1-class compartments (inset right) are fitted with three beds which can be folded into seats, as well as a wardrobe, washbasin and an illuminated cabinet with a mirror. Two compartments can be linked to give more space for group travel.

All passengers can use headphones to access four channels of music controlled by local volume switches and a central control panel in the staff compartment. Vacuum retention toilets are fitted, one of which is equipped with a baby changing table. The car is fully air-conditioned with 4·5 kW equipment supplied by SAB Wabco, with a 380V two-phase supply. Electric heaters automatically ensuring a constant temperature when the outside temperature is between -30íC and 40íC. Fire detectors and alarms are fitted throughout the car, as well as digital CCTV in the corridors and entry-code controlled motion-detecting intruder alarms in all compartments.

The stainless-steel body and underframe form a fully self-supporting welded structure, with mineral wool thermal and acoustic insulation. Bode power-operated plug doors are fitted, with crew-controlled central locking. The sliding electro-pneumatic end doors meet UIC fire requirements, and the fluorescent lighting is backed up with 24V DC emergency bulb lamps. The PSM-50W static converter was supplied by Medcom.

The 25Ana/4 two-axle bogies are designed for 200 km/h operation, and each wheelset is equipped with electromagnetic disc brakes from SAB Wabco. There is an 84 kN magnetic track brake and SWKP 20AS anti-slide electronics. SAB Wabco also supplied the SW4CSP distributor valve.
