 The diesel engines provide year-round service, even when the steam engines are in use, as the high season operation of the line requires three locomotives off-peak, and four locomotives at peak times.In 2018 an experimental locomotive was moved to the railway, powered by electricity, with generation through a hydrogen fuel cell in a tender.The locomotive is intended to demonstrate the capabilities of hydrogen power for the wider rail industry, and has been developed by a consortium consisting of ÖBB Infra (a division of the Austrian Federal Railways), Liliputbahn/TEMO, Air Liquide, Railway Competence and Certification GmbH, and Prosoft Süd Consulting GmbH.
