In the winter timetable of 1980/81, however, suddenly 13 out of 17 trains were designated as railcars (including accumulator cars), but in the summer of 1981 and the winter of 1981/82 only one of 17 trains was not locomotive-hauled.
Im Winterfahrplan 1980/81 allerdings sind schlagartig 13 von 17 Zügen als (Akku-)Triebwagen gekennzeichnet, im Sommer 1981 und Winter 1981/82 wiederum nur einer von 17 Zügen.
