ʻO ke kūkulu ʻana i ke kaʻaahi kiʻekiʻe kiʻekiʻe ICE hou, i hoʻolālā ʻia no ka wikiwiki a hiki i 300 km/h, e hōʻemi i ka manawa huakaʻi ma waena o Munich a me Nuremberg, nā kūlanakauhale nui ʻelua o Bavaria, mai kēia manawa ma luna o 100 mau minuke i lalo o 60 mau minuke.
Ma hope o ka pau ʻana o nā ʻāpana ʻē aʻe ma waena o Nuremberg a me Berlin, ʻo ka manawa huakaʻi holoʻokoʻa mai Munich a i ke kapikala Kelemania e lawe i 4 mau hola ma mua o nā hola 6.5 i kēia manawa. ʻO kahi hale kūikawā i loko o nā palena o ka papahana hale ʻo Göggelsbuch tunnel me ka lōʻihi o 2,287 m. Loaʻa i kēia tunnel kahi ʻāpana keʻa piha o kahi kokoke
150 m2 a me kahi pahu hoʻopakele me ʻelua puka pilikia i waenakonu o ka tunnel ua hoʻokomo piha ʻia i loko o kahi papa o Feuerletten, me ka overburden o 4 a 20 m. ʻO ka Feuerletten he pōhaku lepo me ke one liʻiliʻi a waena, ʻo ia hoʻi nā ʻāpana pōhaku me ka mānoanoa a hiki i ka 5 m a me nā ʻāpana one a hiki i ka 10 m ma kekahi mau wahi. Hoʻopili ʻia ka tunnel ma luna o kona lōʻihi holoʻokoʻa me kahi lau i hoʻoikaika ʻia i loko o ka papahele ma waena o 75 knm a me 125 knm a he 35 knm ka mānoanoa o ka waihona.
Ma muli o kona ʻike loea i nā noi geotechnical, ua hāʻawi ʻia ka lālā o Salzburg o DSI Austria i ka ʻaelike no ka hoʻolako ʻana i nā ʻōnaehana heleuma e pono ai. Hoʻokō ʻia ka heleuma me ka hoʻohana ʻana i nā heleuma 25 mm dia.500/550 SN me kahi kaula wili i ʻōwili ʻia no ka nati heleuma. Ma kēlā me kēia 1 m ʻāpana o ka hale, ua hoʻokomo ʻia nā heleuma ʻehiku me ka lōʻihi o ʻehā mau mika i loko o ka pōhaku a puni. Eia kekahi, ua hoʻokomo ʻia nā DSI Hollow Bars e hoʻopaʻa i ka maka hana.
