The SBB Fhe 4/6 are meter gauge built for the Brünigbahn - luggage railcars for mixed adhesion and cogwheel operation .

The Swiss Federal Railways (SBB) electrified during the Second World War, its meter-gauge Brünig line with the usual standard gauge AC voltage of 15 kV at a frequency of 16 2 / 3  Hz. For the operation they procured a series of 16 baggage railcars (running numbers 901-916) . The railcars were built by SLM with electrical equipment from BBC (7 pieces), MFO (5 pieces) and SAAS (4 pieces) and delivered in 1941–1942 and later redrawn as Dhe 4/6 and Deh 4/6.

The railcars are designed as four-axle adhesion railcars, which have an additional running bogie with a gear drive in the middle. As a result, the two drives can work together on the gearwheel sections. The multiple units ABeh 160/161 built for the Brünigbahn in 2010 are also based on this drive principle.

From 1954 the Fhe 4/6 were relieved on the rack line by two HGe 4/4 I. From 1990 the covering of the through trains Lucerne – Interlaken Ost was completely transferred to the HGe 4/4 II delivered from 1986 .

Conversion for valley shuttle trains

At the end of 1987 the Deh 4/6 913 was converted by the Brünig workshop in Meiringen on a trial basis to pure adhesion operation, whereby the middle gear drive frame was removed. The vehicle was prepared for shuttle train operation (with a control car) on the valley sections of the Brünigbahn and was given the designation De 4/4 II 913 .

The 915 was eliminated from the rest of the Deh 4/6 series due to an accident in 1990; the 905 and 907 were sold to the neighboring Lucerne-Stans-Engelberg-Bahn (LSE) in 1991 . The LSE also rebuilt the 905 between 1991 and 1992, resulting in the LSE De 4/4 121; the 907 continued to be operated as the LSE Deh 4/6 122 before it was also converted into a De 4/4 between 1993 and 1994.

After the 913, between 1991 and 1993 the SBB converted five more Deh 4/6 - the 903, 906, 908, 910 and 912 - according to the same model. The converted vehicles were given the new series designation De 110 000–004 for the first time ; the 913 was the last to be renamed De 110 005 in 1993. The remaining seven Deh 4/6 were also redrawn in 1993 in Deh 120 006-012 and thus continue the serial numbers of the De 110, which means that mix-ups can be avoided during operation.

With the merger of the LSE and the Brüniglinie to form the Zentralbahn (ZB) at the beginning of 2005, all of the remaining vehicles have since returned to the same company.

After the renovation, the De 110 took over the regional trains Lucerne – Giswil, Lucerne – Stans and Interlaken Ost – Meiringen. In these services they were replaced from 2005 by the new Spatz multiple units , but remained as a reserve. After the opening of the new tunnel to Engelberg, two HGe 4/4 IIs will be required on this line, which means that the Interregios on the Interlaken Ost – Meiringen section have to be temporarily covered with De 110 again. The five De 110 001–003 and 021–022 were still in service at the beginning of 2012. The De 110 021 was the last vehicle to be parked in Lucerne by mid-2015.

The Deh 4/6 914 (ex De 120 011) belongs to the zb-Historic as a non-operational museum vehicle and has had the green SBB paintwork again since 2009,
