A total of 152 trams were produced and put into service in Germany (Braunschweig, Jena, Leipzig) and Poland (Olsztyn and Poznań).

[2] The Tramino prototype was developed in cooperation with Autosan and the Municipal Transport Company in Łódź [pl].

Autosan prepared the skeletons of all sections, and the assembly of the first Tramino took place in the halls belonging to the Municipal Transport Company in Łódź.

[28] On 16 January 2018, the Solaris and Stadler consortium signed a framework agreement for the delivery of 50 trams for Kraków.

[31] In February 2019, it was announced that the production of Tramino would be partially moved to the Stadler Polska factory in Siedlce.

The vehicles are fully air-conditioned, feature metro-style seating, and have four doors on each side, each 1,300 mm wide.

[52] The third variant, chosen for the trams ordered by Leipzig, is partially low-floor and equipped with rotating bogies, which pivot more than a few degrees relative to the vehicle's axis.

[14] On 23 November 2009, Solaris signed a contract with the Municipal Transport Company in Poznań [pl] for the delivery of 40 low-floor trams,[2] with an option to extend the order by an additional 20 units.

To fulfill the order, Solaris leased a hall in the Junikowo district of Poznań for the final assembly of the Tramino trams.

[54] Two days before signing the first contract, a prototype Tramino with similar specifications to those ordered by the Municipal Transport Company arrived in Poznań.

On November 26, the Tramino made its first passenger run, and on January 28, it began regular service on Line 14.

[61] On 11 December 2014, a Tramino driven by an intoxicated workshop employee collided with another tram during a technical run, injuring 20 people.

[62] In August 2018, the operation of the prototype unit (S100) was discontinued due to a failure, and the vehicle returned to the manufacturer.

In February 2022, Solaris' spokesperson announced plans to scrap the prototype due to the lack of buyers or lessees and the cost of restoring the tram exceeding its value.

[64][65] In June 2022 and January 2023, two more trams were involved in accidents, colliding with a viaduct at Górczyn [pl]; fortunately, there were no injuries in either case.

[67] In October 2023, a contract was signed with the consortium of Serwis Pojazdów Szynowych and Falkone for the major repair and modernization of the tram to match the series-produced Tramino S105p units.

[69] By the end of May 2015, the first tram was ready[70] and subsequently sent for testing at the Franowo depot in Poznań,[42] which lasted until the second half of July.

[74] The first trial run of one of the trams took place at the Olsztyn depot on August 21,[75] and the deliveries were completed on October 5.

[84] By late September 2018, 5 of the 15 trams were withdrawn from service due to suspected issues with the portal axle bearings.

[86] On 11 July 2011, a contract was signed with Jenaer Nahverkehr GmbH for the delivery of 5 bidirectional, three-section trams.

[87] By the second half of September, all 5 trams had been received,[10] with the official presentation taking place on November 9 in Jena.

[88] All 5 trams were named after Jena's sister cities: Aubervilliers, Berkeley, Erlangen, Lugoj, and San Marcos.

[19] Production of the trams began in December 2013, with the sections of the first unit assembled by March 2014 and the interior fitted.

[92] On 29 June 2017, the operator ordered 7 additional trams (with an option for 7 more) that differed slightly from the earlier models.
