The Espenloh Tunnel is a 2,235 m long railway tunnel on the high-speed line from Hanover to Würzburg . It drives through slopes of the left bank of the Main , north of Würzburg .

course

The route describes a straight line in a southerly direction. The gradient initially rises at 12.5 per mille, and then falls towards the south portal at 12.5 per mille.

The Leinachtal bridge connects to the structure to the north, and the Eichelberg tunnel follows to the south .

The Espenloh transfer point is located in the tunnel . The four points are covered by four main signals , also in the tunnel . A hot box detection system is located in front of the southern tunnel portal .

history

planning

According to the planning status from the end of 1977, two short tubes were planned in the area of the current tunnel: A 320 m long tunnel was to be connected to the Leinachtal bridge, which, after a short cut, was to be followed by a tunnel of 530 m length. Both tunnels were supposed to rise to the south at a rate of 12.5 per mille, while the following falling section (now almost completely in the Espenloh tunnel) was to be realized as a cut. The entire section was planned as a straight line.

construction

Preparatory work began in October 1983. At that time, a total length of 2213 m was planned for the structure.

The tunnel was on March 22, 1984 struck and beaten on 27 August 1985th

At the end of August 1985, Monika Schreier, the wife of the then Würzburg District Administrator, triggered the symbolic final demolition. At that time it was planned to complete the work on the tunnel at the end of April 1986 seven months earlier than originally planned. The tube was completed as the 13th tunnel and it was considered one of the most difficult of the tunnels in the southern section that had been broken up to that point. There was one fatality during the construction work: the miner Johann Merzinger died in an accident at work.

On the night of September 3, 1985, around 2 a.m., a major fire in an electrical and spare parts warehouse at the tunnel construction site caused property damage amounting to half a million Deutschmarks .

The tunnel was built by a consortium of the companies Polensky & Zöllner , Porr and Stuag .

In the planning and construction phase, the tube was located at construction kilometers 298 to 300.
