These are the first modern trams of Latvia, the model "For City" built by Škoda in Czech republic. These are also the first trams in Latvia with normal pantographs. All the communist era models still used the very old fashioned trolley bar systems instead of normal pantographs. In the beginning the Tramways of Riga could only use these new Škodas on only one line, because at other places the overhead catenary wires were not suitable for other than trolley bar use. But now lately the city of Riga has received some infrastructure money from the European Union to renew their tram catenary systems and Riga has also ordered more of these new Škoda trams.

Most of the tram traffic in Riga has been carried out by old communist time Tatra trams, just like in so many other communist countries. All the trams before the new Škodas used trolley poles. These two are of the older Tatra type T3 and they are here driving along the Slokas iela on tram line 2 on the 7.10.2012.

Two Tatra T6B5SU trams on Slokas iela on tram line 2. The "SU" at the end of the version name refers to Soviet Union and the fact that these tramlines are of the extremely broad 1524 mm gauge. Compared with the familiar Tatra wagons of many other eastern European countries these wagons even look extremely broad.

After renovation the Tatra T6B5SU trams look still fairly modern.

After Latvia's regained independence but before renovation of the old trams, there was a time when almost all Riga's trams were covered by ad tapings and they were in a fairly bad overall condition.

The town of Liepājā has one tramline from Brīvības iela via the train station to the Mirdzas Ķempes iela. Liepāja ordered 12 Koncar NT2300 trams from the Croatian company Koncar and their delivereies began in 2020. Earlier Liepāja had only four Tatra KT4SU trams (a modified model of the Czech Tatra KT4 for Soviet Union) and eleven KT4D trams from the German cities of Cottbus, Gera and Erfurt, all dating back to the communist DDR times.

The city of Daugavpils (The name means bridge over the river Daugava) is a fairly large but not so very rich, very Eastern European looking city in eastern Latvia. Daugavpils has a tram system with old broad gauge 1524 mm tracks and very old trams from the old communist times dating back to 1946.

Wikipedia tells us the following about Daugavpils trams:
The rolling stock comprises RVR-6 vehicles built in Riga and the KTM-5 and KTM-8 built in Ust-Katav, Russia. In 2002, 12 Czech-made T3D vehicles were purchased secondhand from the tram system in Schwerin, Germany. In 2013 a contract was signed to purchase 12 new Belarusian Belkommunmash trams as part of an infrastructure renovation project. The new trams were expected to arrive in Daugavpils in August and to start running not earlier than October. However the contract was cancelled.
New Russian-made UKVZ KTM-model trams were purchased in March 2014. In September, eight partially low-floor 71-623 trams and four low floor 71-631 trams were delivered.

The Daugavpils tram in this and the following pictures is a model KTM-5 tram from Ust-Katav, Russia. As such they are quite a sight today in a western EU country.

Note the rope that the driver has to manually pull on the outside of the tram whenever the trolley bars need to be switched from the overhead catenary wires. RVR-6 trams on line 1 on the "18th November street".
