The DSB series ER are four-part electric multiple units designed by the manufacturer ABB Scandia in Randers for Danske Statsbaner in Denmark . They were conceptually developed from the MF series diesel multiple unit . The design is also known in Denmark as the IR4 .

Design and technology

A unit consists of four car bodies: a motor car ER (2001–2044), two intermediate cars FR (2201–2244 and 2301–2344) and another motor car ER (2101–2144). It runs on a total of five bogies (including three Jakobs bogies ) with a Bo'2'2'2'Bo 'wheel arrangement and is driven by four electric motors with 420 kW each.

The individual vehicles are equipped differently:

model series	Vehicle numbers	Seats	length	Type	power	Remarks
HE	2001-2044	1st class: 24 2nd class: 27th	20,530 mm	Railcar	2 × 420 kW	with pantograph, luggage compartment 2018–2044 with coffee machine
FR	2201-2244	2nd class: 52	17,730 mm	Middle car		with pantograph
FR	2301-2344	2nd class: 52	17,730 mm	Middle car		without pantograph
HE	2101-2144	2nd class: 52	20,530 mm	Railcar	2 × 420 kW	without pantograph

The units of the ER series can be driven in a group with multiple controls with the three-part diesel multiple units of the MF series. The special feature of both series is a fold-away driver's cab that can be converted into a passage. In this way, a maximum of five ER or MF units can be combined to form a continuous train. Several units are connected using automatic Scharfenberg couplings . Thanks to the rubber bead, the intercar transition is draft-tight. The multiple units are equipped with the ATC train control system for Denmark.

The ET series , which runs between Denmark and Sweden , are similar trains . These trains, which are a new development based on the same concept, but without Jakobs bogies, are outwardly similar to the ER and MF series, but cannot be operated in combination with them.

history

The electric multiple units were originally developed for regional traffic on the electrified routes in the Copenhagen area and were therefore more simply equipped compared to the MF diesel series designed for long-distance traffic . Later, however, the area of ​​operation was expanded to include the electrified long-distance route Copenhagen - Odense - Fredericia - Sønderborg and the interior fittings were upgraded to the level of the MF series.

ERK / ERF

In connection with the licensing of Kystbane to DSBFirst (from December 2011 DSB Øresund ) from January 11, 2009, the vehicles ER 2001-2020 are internally referred to as ERK , with the K standing for Kystbane. These trains are used normally on this route. If they are not all needed there, they are loaned back to DSB, where they are used primarily between Østerport and Ringsted.

In terms of circulation, the ER 2021–2044 are called ERF ( F for fjerntog ). These trains serve long-distance traffic on the electrified routes.
