The high-speed line (also high-speed railway , ital. Ferrovia ad alta velocità ) Rome - Naples is one of the most important north-south connections in Italy and is an important section of the Berlin-Palermo railway axis ( TEN axis No. 1 ). The first 186 Kilometers from Rome to the connection structure Gricignano have been since 19. December In operation in 2005, the remaining 18 Kilometers through Naples since 13. December 2009.

history

The construction of the 204.6 Kilometers long route

• 39.0 km of tunnels, of which
  • 26.4 km in shield drive
  • 12.6 km in open construction
• 39.0 km of viaducts and bridges
• 17.5 km shortcuts
• a new train station in Napoli Afragola

In January Test drives began in 2005. During test drives, an ETR 500 high-speed train with eight intermediate cars July 2005 with 323 km / h set a new Italian speed record for rail vehicles. At that time it was envisaged that ETR-500 trains would be on the route for 330 allow km / h.

The preliminary operation was on 12. September Recorded in 2005.

Commercial operation began on 23. January Recorded in 2006 with two train pairs per day. The completion of the section between Bivio Gricgnano and Napoli Afragola station, which was still outstanding at that time, was planned for 2008. However, the section was not opened until Jan. December Opened in 2009. Construction work on the new Naples Afragola station, designed by Zaha Hadid , continued with delays for years; he was born in June Opened in 2017.

technology

The line is equipped with GSM-R and ETCS Level 2 (without signals, from Alstom ). Due to the lack of a fallback level, the system was designed for particularly high availability and reliability . The availability in areas in which only ETCS was used turned out to be greater than in node areas in which other train control systems were also installed. To test the system, the line load was gradually increased from initially 4 trains per day. The minimum headway time is two minutes and 30 Seconds. In March In 2014 the SRS started upgrading the line 2.2.2 to the SRS 2.3.0d . The work should be in December To be completed in 2015. The EU paid half of the cost of six million euros.

19 signal boxes , 70 GSM-R base stations and several radio block centers were built along the route . The GSM-R base stations are connected to one another via an SDH ring network ; the GSM-R network is largely redundant. According to the planning status of 2000, 50 base stations were planned, which as a rule should serve two (in individual cases three) channels.

The route is at 25 kV / 50 Hz electrified. At both ends, trains go to the conventional Italian 3 kV system over.

business

The new line extends from Salone (km 10.9) to Bivio Gricignano (km 195.3). There closes an 18.6 km long section to Napoli Afragola train station. In Afragola you can change to the high-speed line towards Battipaglia - Reggio Calabria , to Circumvesuviana and to local transport.

The travel time between Rome and Naples has been reduced to 1 hour 10 minutes after completion of the route.
