The electric railcars of the ET 30 series (from 1968 the 430 series of the DB ) were designed for local express traffic in the Ruhr area . They consisted of two railcars and mostly a close-coupled intermediate car, which were connected by car transitions with rubber bulges. Two intermediate cars could also be carried. The train carried the first and second carriage classes . The vehicles were discontinued under the series designation ET 30 (railcar) and EM 30 (intermediate car). In terms of design, the railcars were based on the ET 56 series (later 456) developed in 1952 , but had significantly more drive power.
history
The first railcars were delivered to the Federal Railroad in mid-1956. Since there were no electrified lines in the Ruhr area at that time, 18 multiple units were used in the Munich area and six in the Nuremberg area. With the beginning of the electrification of the railway lines on the Rhine and Ruhr in 1957, the Munich multiple units came into their intended area of operation, the Nuremberg ones did not follow until 1972. From 1972 all railcars were stationed at the Hamm depot.
The multiple units, also known as egg heads because of their distinctive head shape, have been the hallmark of fast local public transport in the Ruhr area for decades. They were able to accelerate at 0.7 m / s² and were able to reach a cruising speed of 60 km / h with an average bus stop of 2½ kilometers and a stop of 30 seconds. Since the railcars did not have an electric brake, the brake pad wear was very high.
The cars of both car classes were designed as open-plan cars. The seating arrangement was 2 + 1 in 1st and 2 + 2 in 2nd carriage class.
With the completion of the island electrification of the important Cologne - Düsseldorf - Duisburg - Essen - Dortmund axis in 1957, the multiple units here took over all passenger train services and some express train services. But he also drove the Westfalenland express train from Bielefeld to Frankfurt am Main in the early 1970s.
In 1968 the numbers of the multiple units and side cars were changed to the new UIC class designation 430 (or 830 for the non-powered intermediate cars). The ocean blue / beige color scheme common in the late 1970s was given to the first units from 1980, a total of 13 multiple units were painted in this way. In the same year, the Federal Railroad began to retire the first severely corroded multiple units. The last 430 disappeared from the tracks of the DB in 1985.
Constructive features
Like the ET 56, the car bodies were designed as a self-supporting tubular steel frame; the cars had aprons and a closed floor pan to reduce air resistance. The wide, eight-part folding doors that were closed pneumatically were striking. Compared to the ET 56, the electrical equipment was newly developed so that it was much more powerful. There was a pantograph each at the end of the railcar to the middle car. The multiple units were coupled to each other via Scharfenberg couplings . The ET 30, like all " egg heads ", were painted red, the roofs were gray and the aprons were painted in an anthracite color. The car body and the apron were separated by a wide decorative strip of beige. The front windows were initially framed in black, but later this was omitted. The DB logo was located below the front window.
The drive was carried out by four paw-bearing motors in the two end bogies .
Whereabouts
What has been preserved is a four-part set (ET 30 014) with a special bar car, which was exhibited in the DB Museum Koblenz branch in Koblenz for ten years . However, since the substance of the unit was so bad by the end of the deadline at the end of 1996, one power car and the two intermediate cars were dismantled. Only the powered end car 430 414 is preserved. It is located at the Friends of the Preservation of Historic Rail Vehicles Association (FzS) in Stuttgart at the rail transport company (SVG).
