Storstockholms Lokaltrafik SL is a really big operator running buses, trams, the Stockholm metro, commuter trains around Stockholm, a narrow gauge train network from the Stockholm East (Stockholm Östra) station as well as some very special trains and trams such as the Lidingöbanan, the Saltsjöbanan and the Tvärbanan routes.

This picture shows two of SL's newest commuter train units of the class X60, which is an Alstom built train of the type Coradia Nordic. As you can see, two Coradia Nordics in a row makes a really long train.

Another view of two Coradia Nordic X60 series trains just leaving Stockholm C. The trains look immensely long even when a long zoom causes a shortening effect in the picture.

Memories from days gone by: A class X1 train approaching Stockholm central station on a snowy winter day 19.1.2008. Nowadays it is almost impossible to find any of the X1 trains any more, because the modern Coradias of the class X60 have replaced them.

Stockholm got its first electric trams in 1901 and tram traffic kept expanding until then in 1967 Sweden decided to change all road traffic from the English style left hand traffic to the more normal keeping to the right. This of course meant getting rid of the old tram tracks which were by then on the wrong side of the street. One line with modified historic trams was kept however, and based on this line no 7. a new start has been made. There is currently still only one tram line in the city center, but there are light rail type fast trams elsewhere. The island of Lidingö is served by Lidingöbanan, which for a long time had over 50 years old trams, but in 2015-16 got brand new bidirectional trams from CAF in Spain. The Tvärbanan is a ring route a bit further away. There the tracks are like train tracks, but the wagons are clearly trams. And then there is the Saltsjöbanan, which is more of a real train.

Before receiving their own new Flexity Classic trams, SL rented trams from elsewhere for test traffic on the city center line no. 7. This one is also a Flexity Classic, but rented from the tramways of Linköping and then just taped to get an "SL look".

Since 1991 the fund Stiftelsen Stockholms Museispårvagnar and the society Svenska Spårvägssälskapet have been keeping a live museum tram traffic on the line 7B, Djurgårdslinjen, with historic trams not only from Stockholm but also from other cities. This one is a so called Ängbyvagn, class (littera) A24B which were for a very long time used at the Lidingöbanan. It is built by Asea in 1949.

Roslagsbanan is a narrow gauge railway system operated by SL from the Stockholm Östra station. It has a somewhat exotic gauge: 891 mm and it uses 1500V DC current just like typical trams do. It has 3 branches and operates to the north and to the east of Stockholm. Since 2013 the operator has been Arriva Sverige on behalf of SL. Presently all the trains are similar and they were built by ABB in 1988-1995. The motorised coach is called littera (type) X10p. However, new trains are already on order from the company Stadler.
A typical Roslagsbanan train is composed of one motorised coach, one middle coach and a steering wagon.

Lidingöbanan serves the island of Lidingö. The line starts from Ropsten metro station, then crosses a huge bridge over to Lidingö and then finally splits into two branches, the main line being between Ropsten and Gåshaga brygga. It is marked as line 21. The line is normal gauge 1435 mm and it is 9,2 km long. There are plans to connect the Lidingö line and the city center tram line no 7. to provide one single service.

This is history by now: The over 50 years old Lidingöbanan trains in 2003. After all the modifications it was hard to say if these should have been called trams or trains.

This museum tram is seen here on the museum tram line 7B near Djurgården, but this is a tram built for the Lidingöbanan by Asea in 1944 and it shows how the trams used to look like before all the modifications and modernisations. Compare with the previous picture.

Saltsjöbanan (salty sea train) starts from the Slussen metro station close to the old town of Stockholm and leads south to Saltsjöbaden (salty sea bathing place) in Nacka in around 19km long line. It is normal gauge 1435mm and operates with 750V DC. The trains still used today are of the classes C10 and C11, which are old used metro trains of the class C8 but modified to take electricity using a pantograph from above. New trains are expected to arrive soon.

Notice how this old ex-metro train has received funny metal "bumps" at its sides to prevent stupid passengers from falling from the platforms into the gap between the train and the platform.

In addition to the former metro trains, later modified for use on the Saltjöbanan line, a couple of old, historic trains and coaches still exist from those days when Saltsjöbanan still was a private venture which had nothing to do with the present day SL. These historic trains are used very rarely, so there have not been many opportunities to photograph them during recent years. However, here we see Saltsjöbanan's EMU motor wagon no.15. This one and its steering cab coach no.22 were built by ASEA in 1912.

Tvärbanan, in English Cross railroad, also known as Nockebybanan, is a light rail system, which in most places operates like a train but in certain places goes to streets and runs like a tram. The long line runs around the whole city center from Sickla in the southeast to Solna in the north cruising around the city in a clockwise direction. The trams used are Flexity Swift trams, known in Stockholm as class A32. Newer trams have been ordered from CAF in Spain and these will then be the class C35.
