The Burgberg Tunnel is a 306.65 meter long railway tunnel on the Nuremberg–Bamberg railway line. The building, which was inaugurated on August 25, 1844 and is now a listed building, is the oldest railway tunnel in Bavaria. The south portal is flanked by two Bavarian lions. The two statues of above-average artistic quality were created by the sculptor Johann von Halbig.

Inaugurated on August 25, 1844, and now a listed building, it is the oldest railway tunnel in Bavaria. As part of the Nuremberg–Ebensfeld line expansion, a second tube was built east of the old tunnel. ... also 306 meters long, in order to preserve the historic portal situation after construction was completed. ... The second tube was put into operation on August 15, 2016." Quote Source: de.wikipedia.org/wiki/Burgbergtunnel_(Erlangen)
