Amarube is known with Amarube Viaduct (余部橋梁), a railway bridge in the Kami Town, Mikata District, Hyōgo Prefecture (兵庫県美方郡香美町), on JR West's San'in Main Line between the stations of Yoroi and Amarube. There was a tragic incident involving this viaduct in the past...
On December 28, 1986, around 1:25 pm, an out-of-service Miyabi train traveling from Kasumi Station was caught by strong winds from the Sea of Japan, and all seven passenger cars of the train were blown from the bridge, with only a few bogies remaining on the tracks. The locomotive's weight prevented its derailment. The cars fell directly below, landing on a fish-processing plant. Five women working at the plant and the train's conductor died in the accident. Five others in the plant and one food-service worker aboard the train were seriously injured. This was the first disaster since the opening of the bridge. The accident is attributed to human error. Although the 25 m/s (56 mph) winds activated warning devices, the train proceeded across the bridge.
Here is a recent article I just found on Amarube Viaduct:

P.S. The following map suggests that construction of Kasumi (香住)-Hamasaka (浜坂) portion of San'in line in early 20th century was difficult:
