Years ago it was hard miner’s work to get through a mountain in order to build a tunnel. Engineers, surveyors and other experts worked on tunnels but also many Italians who had a good reputation as miners. An office in Alf was responsible for all rail work between Kinderbeuern and the rail bridge in Eller, also for building the two tunnels of Reilerhals and Prinzenkopf.
Because of electrification of the Moselle line at the beginning of the 1970’s, all tunnels had to make room for cables and a minimum distance to the roof, which meant that all tunnels had to be sunk to a lower level.
Entering the tunnel of Reilerhals, the ‘Kanonenbahn’ leaves the Moselle valley, crosses the Eifel and only just before Trier near Schweich rejoins the Moselle.
