The Yoa2 was a Swedish four-part electric railcar that was procured by Statens Järnvägar (SJ) around 1960. The trains were soon called Paprikatåg (paprika train) because of their coloring . After the introduction of the new series designation for the SJ in the 1970s, the railcar was run as the X9 .

history

The trains were built between 1959 and 1963 by Hilding Carlssons Mekaniska Verkstad in Umeå , the electrical equipment was built by ASEA . The concept was adopted from the X20 / X21 series railcars delivered to TGOJ in the mid-1950s . At that time, SJ had placed an order for narrow-gauge railcars with Hilding Carlsson, but no longer needed these vehicles. That is why it was converted into an order for 14 standard-gauge railcar units, consisting of motor cars and intermediate cars.

In contrast to the X20 / X21 , the X9 had straight fronts to create a more stable structure. The wagons were not firmly coupled, so they could be exchanged or the train length varied without any problems. The original order was supplemented so that finally 23 trains were delivered. The series designation was changed after the reorganization of the series in 1970 to X9A / X9B for railcars and UA9 , UAB9 and UB9 for intermediate cars.

The first train was delivered in late 1959. The railcar units still received the old Swedish type designation Yoa2 . Great attention was paid to comfort. The interior was designed as a salon and there was a folding serving table and footrests at each seat.

The name Paprikatåg came from the exterior of the trains, which were painted in strong orange-red. The roof was originally green. A multiple unit consisted of four parts, which usually ran in the train set X9a + UA9 + UB9 + X9b.

In total, Hilding Carlsson built the following railcars and sidecars :

model series design type Length
in mm		 Weight Seats number Special
X9a Railcar with transformer 17,500 26 tons 24 (2nd class) 23
UA9 1st class intermediate car 17,400 16 tons 30 (1st class) 18th
UAB9 Intermediate car, 1st and 2nd class 17,400 16 tons 17 + 18 2
UB9 2nd class intermediate car 17,400 16 tons 54 (2nd class) 22nd
X9b Railcar without a transformer 17,500 21 tons 46 (2nd class) 23

commitment

The trains were primarily used as express trains in southern Sweden, especially in parts of Skåne and around Gothenburg , and also ran between Stockholm and Dalarna . They quickly became popular with travelers because they offered a very high level of comfort for the time. The trains were given names such as Mälardalen , Siljan or Östergyllen , these names were attached to the front of the railcars.

During the 1970s, the Dalarna trains were moved to Skåne and around Gothenburg and ran on the Malmö - Helsingborg and Helsingborg - Hässleholm - Kristianstad routes . The name tags were replaced by the SJ mark.

In 1987, the railcars disappeared from long-distance traffic and were only used in local traffic around Gothenburg, such as on the Gothenburg – Strömstad and Viskadalsbanan Borås - Varberg routes. The railcars were given a new coat of paint, which significantly changed the appearance of the trains.

In the 1990s, the trains began to be parked, the last of its type was decommissioned in 1999.

Today there is only one unit with three cars (X9A 137 + UB9 2352 + X9B 138) at Svenska Motorvagnsklubben .
