It is located on the Prague–Plzeň railway line at Ejpovice and therefore bears its name.

Since its commissioning in 2018, it has been the longest railway tunnel in the country.

[1] It shortens the journey between the city of Plzeň and the town of Rokycany from 20 to 11 minutes.

The tunnel will remain the longest in the country until the planned Ore Mountains Base Tunnel between the Czech Republic and Germany surpasses it.

When building the two tubes, a tunnel boring machine from the manufacturer Herrenknecht was used, with which up to 182 meters were driven per week.
