In June 1991, the Austrian Federal Railways (ÖBB) implemented the "New Austro-Takt 91" as part of a significant timetable change. This initiative was the first phase in creating a coordinated public transport network across Austria. It was the most considerable timetable adjustment in ÖBB's history, leading to a noticeable increase in the number of trains and services on many routes.
The D 704/705 was an express train that operated from Vienna Westbahnhof, passing through Amstetten and Selzthal on its way to Bischofshofen. This service ran only on specific days, such as weekends and holidays, and was introduced with the "NAT 91" timetable. Unlike most trains, it took an alternative route through the Gesäuse and the Enns Valley, bypassing Salzburg. Although this route was shorter in distance, it did not offer a faster travel time due to the lower quality of the track and a higher number of stops. Under the "NAT 91", the train took five hours and eight minutes to complete its journey. In contrast, the direct InterCity (IC) trains that operated every two hours via Salzburg could make the trip to Bischofshofen in just four hours and eleven minutes. Rather than serving solely as a direct connection between Vienna and Bischofshofen, this train primarily functioned as a service to various tourist destinations in the Enns Valley. Notably, the train used a variety of rolling stock and traction units, depending on what was available and not lacking for the day.
