On 16 November 2013, high-speed testing of Poland’s ETR 610 Pendolino trains began on the CMK trunk rail line. Test runs are being carried out on the weekends of: 16-17 November, 23-24, November 30 Nov – 1 Dec, and 7-8 December.
During the course of the tests, which take place approximately between 10:00 and 15:00hrs, normal train services are suspended over the CMK, and the trains that were due to run are either cancelled or re-routed through Chestochowa.
The speed and breaking trials are part of the certification tests for the Alstom-built Pendolino trains being delivered to Poland. Twenty 7-unit ETR 610 sets, together with a new depot and a 17-year maintenance contract were ordered by PKP IC for 2,640 million PLN (65 million euro).
The trains are being certified for up to 250 km/h (155 mph) running. With a requirement for a 10% safety margin the objective has been to work up to a speed of 275 km/h (171 mph).
On the first day of the trials on 16 November 2013, the test train reached 242 km/h. On 17 November, it reached a speed of 270 km/h, breaking a little publicised record of 250.1 km/h set by an earlier generation Pendolino test train some 19 years earlier.
Today, the test train, with Rail Minister Andrzej Massel and other rail VIPs on board, achieved its objective and exceeded the 275 km/h target reaching a top speed of 291 km/h (181 mph).
To enable the high speed tests to take place, the section of CMK track used for the tests (between Gorą Wlodowska and Psary) had to be re-fettled with new ballast, and its overhead catenary replaced. For today’s record-breaking run the 3k DC voltage supply was tweaked by PKP’s electricity distribution company, PKP Energetyka.
Sadly, there is nowhere on Poland’s railway network actually certified for 250 km/h (155.3 mph) running, although a number of sections of line, including a short section of the CMK trunk line, are certified for 160 km/h (100 mph) running. PKP has plans to upgrade the CMK for 200 km/h (124 mph) running, and then in stages up to 220 km/h (137 mph), and eventually to 230 km/h (143 mph).
