Summary
[edit]
| Description |
Deutsch: Die Fischgrätenzahnstange Peter besteht wie die von Strub aus einem schienenartig geformten Träger, in dessen Kopf beidseits waagrechte Zähne ausgefräst werden. Die Zahnstange ist einfacher herzustellen wie die von Locher und hätte auch für gemischte Bahnen verwendet werden können. Sie war für die Karlsbad-Dreikreuzberg-Bahn mit 500 ‰ Steigung vorgesehen, deren Bau wegen des Ausbruchs des Ersten Weltkrieg eingestellt wurde. |
