BLT or Basellandtransport is a company owned by the Baselland Kanton. It is the fusion product of Birseckbahn BEB (a line from Basel up via the river Birs valley to Arlesheim, Baselland, and Dornach, in Kanton Solothurn), the Trambahngesellschaft Basel-Aesch, which operated on the other side of the Birs valley from Basel to Aesch and the Birsigthalbahn, originally a real train line with narrow gauge steam trains, designed to be built all the way from Basel via the Birsig river valley to Porrentruy, but which was never built further than Rodersdorf. The combination of all this led to the construction of line 10 Dornach-Arlesheim-Basel-Flüh-Rodersdorf, which is today one of Europe´s longest tram lines where one stop in the middle (the old Leymen station) actually is in France and also line 11, Aesch-Basel-St. Louis border, another remarkably long line, with train-like fast service at the end close to Aesch. It takes more than an hour for a tram to run through the line no. 10 and most of the line is clearly built for trains, not trams. The old stations look pretty funny with today´s low-floor trams. In 2022 also the WB Waldenburgerbahn was integrated into BLT.

Basel is a city of only about 200 000 inhabitants but still an impressive tram network, with two service companies BLT and BVB operating on the same network. Lines are long and so are the trams.

The tram lines in Basel are long, and so are the trams. Two companies, the Basel City BVB and the Baselland BLT operate on the same network. The longest lines take well over an hour to drive from end to end and the lines are extended a long way to the countryside. Here BLT low floor articulated tram no. 219 with two joints together with a similar but non-low floor, one joint wagon as a trailer at Wolfgottesacker in May 1999.

These are the new trams of BLT Basellandtransport. This Be 6/10 no.153 is of the type "Tango" built by Stadler since 2008. It is 45 metres long and has place for 94 sitting and 182 standing passengers. 75% of the tram is low-floor.

These trams were built by Schindler Waggon AG in Pratteln 1978-81 and some of them like for example this one no.239 were elongated 1986-1999 by adding an extra low-floor section in the middle of the tram. Here we see a long train which consists of one elongated and one non-elongated Schindler wagon.

This Schindler tram Be 4/6 no.247 was never elongated with a low-floor piece and it was mainly used as a trailer.

A similar composition like the one shown above, here we have a combination of one elongated Schindler tram of the type Be 4/8 plus one non-elongated of the type Be 4/6 here on line 17 by the tram stop Schifflände. This type of combinations were the standard BLT trams around the year 2000 on BLT's main tram lines 10 and 11, but nowadays they are only seen on the rush-hour additional line 17. New Stadler Tango trams have replaced them on the main lines.

Here we see a composition that was very typical for the BLT line 10 at least during the years 1995-2010. The wagon in the front is an elongated Be 4/8 with a later added low-floor middle part. The wagon used as a trailer is one of the 100 series Be 4/6 wagons which were new during the 1970s.

This picture was taken only minutes after the one shown above. An exactly similar Be 4/8 + Be 4/6 combination is here arriving at the tramstop Arlesheim Dorf. But this tram composition is now arriving from the direction of Basel city, whereas the tram in the picture shown above was heading there.

This is the same tram composition that was already shown in the picture above, but now we see the trailer wagon Be 4/6 of the 100 series a bit better. These trams were from the 1970s.

Partly low floor articulated tram Basellandtransport BLT no. 211 on its way to Dornach on line 10 at Elektra Birseck, Münchenstein, Kanton Baselland. As a trailer coach was an unidentified 100 series articulated tram. This was one of the longest combinations seen in Basel in that time. Line 10 takes over an hour to ride end to end, and the line runs on the terrains of three Swiss Kantons (Basel Stadt, Baselland and Solothurn) and two countries. One stop is in France.

This is a Basel BVB Düwag Be 4/6 tram, which had been sold to the Baselland Kanton tram company BLT and repainted in BLT´s yellow and red colours. When BVB started using its first brand new Siemens Combino trams in 2001 and 2002, many the old Düwags were put out of service. Some were donated to ex-Yugoslavia, but some - like this one - were sold to the "neighbors", the neighboring company Basellandtrafik BLT, operating on the same tracks. BLT replaced older trailers with the Düwags. The old Düwag actually looks a lot better in its new painting. It is 19,735 m long, weighs 23 tons and has 40 places to sit and place for 113 standing passengers.

Another view of the extremely long combination at the line 11. "St Louis Grenze" end station by the French Alsace border in Basel. First wagon is a Be 4/8 and the trailer is a Düwag Be 4/6. The first wagon was originally built as Be 4/6 between 1978 and -81 by Siemens. BLT had 66 of these wagons. Many of them - like this one - were later retrofitted with an extra middle part in the low floor style to become a Be 4/8 wagon, 26,2 meters long, but the lengthening was done nicely in the same style, not spoiling the wagons as Basel BVB did. The trailer wagon, Düwag Be 4/6 was built some time between 1967 and -72 by German Düwag, Siemens and BBC. It is 19,7 meters long. It is a huge combination as a tram.

Switzerland is full of strange small private railroads. One of the smallest ones was WB or Waldenburgerbahn, which operated a really narrow gauge railroad with only 750 mm rail track gauge - the only one in the country with just a 75 cm gauge width. In 2021-22 the line was rebuilt and regauged to 1 metre gauge and it is now a part of the BLT tram network as tram line no.19. It runs from Liestal, the small capital town of Kanton Baselland, some 20 minutes, only 13 km, uphill along a river valley, sometimes in full countryside environment, but also serving small suburban style villages, ending at the village of Waldenburg. Waldenburgerbahn was opened for traffic in 1880. It brought workers to work at the Liestal area factories and it also connected the small villages of the river Frenke valley to the "real" railroad at Liestal station. Since 1985 WB had six modern two coach EMUs, running on 1500V DC and on the 750 mm gauge. It looked like an odd crossing between a tram and a real train.

During 2019 it was announced that the two companies BLT and WB will be fusioned. The whole railways system of WB was regauged from 750 mm to metre gauge and WB's trains were replaced by new trams painted in the yellow and red colours of BLT.

Waldenburgerbahn BDe 4/4 no. 12 with matching coach no. 112 at Liestal station. WB bought these trains, which look like a cross between trams and trains in 1985-86 and they had six pairs of this kind in operation. The motor wagons could also be used alone, without the trailer, since the motor wagon had a cockpit at both ends.

Waldenburgerbahn WB BDe 4/4 no. 14 with its trailer coach no. 114 stopping at the old Bad Bubendorf station. Note the motor wagon´s special cargo department for transporting cycles - many people continued with bike from Liestal station to their work. The old station is also fascinating - unfortunately it is here behind the train - it even has a water outlet to fill the tanks of the old steam engine that still used to run as long as the line was 750 mm gauge.

There it goes. The Waldenburgerbahn BDe 4/4 was much like a tram and had actually been built with many components from trams of the Swiss "Tram 2000" design concept.

These were the previous trains of Waldenburgerbahn before the BDe 4/4 models shown above. This one was also called BDe 4/4 (earlier BFe 4/4) but these trains were from the year 1953 and they were taken out of use when the ones shown above emerged in 1985.

These are now the new tram-trains running from 2022 onwards on the Waldenburgerbahn. As already mentioned above, the whole railroad was totally rebuilt and regauged to 1000 mm gauge. These new trams were designed by the company Vossloh-Kiepe and after Stadler bought Vossloh's train production they are now called Stadler Tramlink. The Waldenburgerbahn train route has also been renamed to Basel tramline no.19 from Liestal to Waldenburg,
