The Class 420 (Шаблон:Lang-de) is a commuter electric multiple unit train type in service on German S-Bahn networks since 1972. Their use in Munich during the 1972 Summer Olympics earned them the colloquial name Шаблон:Lang (Olympic multiple unit).

Design

Livery variations

Each of the three prototype sets received a different livery. 420 001 had an orange and white livery, 420 002 had a blue and white livery, and 420 003 wine-red and white livery. A public poll over the livery of the S-Bahn trains was held in Frankfurt, Munich and Düsseldorf. Munich received blue trains, Düsseldorf chose orange and Frankfurt also received orange liveried trains due to economic reasons, despite opting for the red livery.

Units used on Munich S-Bahn services to the airport received a light blue livery.

All units still in service were repainted into the traffic-red livery.

Between April 2005 and January 2006, two trains (420 400 and 420 416) received an experimental refurbishment at DB Krefeld-Oppum works, and were branded as "420Plus". Changes to the interior included new seating, the addition of air conditioning and windows in the inner car ends, passenger information displays and push-button door openers. Entry into passenger service followed in April 2006.

Car body

The car bodies of the end cars are made out of steel. The intermediate cars have aluminium car bodies. Beginning with the 2. batch units, the car body construction of the end cars was changed from steel to aluminium, in order to save weight.

Electric systems

The electrical equipment was built by AEG, Brown-Boveri, and Siemens. They are the first DB trains that were equipped with thyristor-phase control. Each bogie is fitted with two mixed current commutator motors. The current of the traction motors is controlled steplessly over two asymmetrical semi-controlled rectifier bridges in sequence.

History

Munich

The first unit was presented in Munich on October 30, 1969. Entry into service on the Munich S-Bahn was in May 1972. The last original Munich S-Bahn units were withdrawn in December 2004.

15 refurbished former S-Bahn Stuttgart sets entered service on the Munich S-Bahn network in 2014. 21 further trains are scheduled to enter service in Munich, in order to reduce the shortage of rolling stock due to the refurbishment of Class 423 trains. These former Rhine-Ruhr S-Bahn units will be fitted with Linienzugbeeinflussung (LZB), which enables them to run on the Stammstrecke.

Stuttgart

The last trains (420 450 and 420 461) were withdrawn from Stuttgart S-Bahn services after an official farewell run from Plochingen to Stuttgart Hauptbahnhof on November 4, 2016, followed by five scheduled public farewell runs on the same day.

Frankfurt and Rhine-Main area

The trains entered service in the Rhine-Main area in April 1978.

The last trains were withdrawn from Frankfurt/Rhein-Main S-Bahn services in November 2014.

Cologne and Rhine-Ruhr area

Class 420 trains entered service in the Rhine-Ruhr area in May 1974. The trains had smoking and non-smoking cars.

Stockholm

In 2003, 15 sets were lent to Storstockholms Lokaltrafik for use on Pendeltåg services around Stockholm. These SL Class X420 trains underwent modifications, which included changes to the cabs, the addition of Swedish Automatic Train Control, and boards to cope with the lower platform heights in Stockholm. The trains were scrapped after their withdrawal.
