This narrow-gauge railway was originally planned in 1863, but did not open until 1902. The line runs for 18 miles between Jenbach and Mayrhofen, and services remained popular for many years, especially among tourists, for the great views of the Tyrol region.
In the mid 1960s, the railway was threatened with closure. However, the owners pulled off the feat of not only managing to stay open, but also of increasing their services. The line has stayed open at its entire original length to the present day. In 1993, the last operating steam engine was finally withdrawn from standard service. Although most services are powered by diesels, some steam engines are used occasionally at special events.
