Tyskie Linie Trolejbusowe

Tyskie Linie Trolejbusowe (TLT) is the municipal trolleybus operator in Tychy, Poland, and one of only three functioning trolleybus systems in the country, alongside Gdynia (with Sopot) and Lublin. The company operates a fleet of trolleybuses and electric buses on a network that has grown from a single experimental 4-kilometre line launched in 1982 into a modern, largely low-floor operation. TLT was formally established in 1998 as a limited liability company (Spółka z o.o.) spun off from the local public transport enterprise, Przedsiębiorstwo Komunikacji Miejskiej. It is responsible for running trolleybus lines under the coordination of the Metropolitan Transport Authority (Zarząd Transportu Metropolitalnego, ZTM). The operator's fleet has evolved from Soviet-built ZiU-9 trolleybuses and Polish Jelcz models to modern Solaris Trollino and Solaris Urbino electric buses. TLT emphasises environmental friendliness, accessibility and passenger comfort, with fully low-floor vehicles, onboard audio-visual route information, and a green livery. Its slogan is "Ekologicznie do celu!" (Ecologically to the destination!). The company has benefited from European Union and national environmental funding for vehicle purchases and infrastructure modernisation. TLT's network is powered by a 660 V DC overhead catenary system, with over 40 km of single-track wiring and three traction substations. Recent investments include battery-equipped trolleybuses capable of running off-wire for extended distances, and the integration of electric buses on selected lines. The company remains a locally focused public transport provider, wholly based in Tychy, and continues to modernise its fleet and infrastructure.

The history of trolleybus transport in Tychy began on 11 February 1982, when construction of the first experimental trolleybus line was ordered by the provincial governor (wojewoda). The line was opened on 30 September 1982, running 4 kilometres from the bus depot along Piłsudskiego and Dmowskiego streets to Jana Pawła II street. Tychy was chosen for the experiment because its wide streets were suitable for trolleybus operation. On 30 October 1982, the governor approved the expansion of the network. Early trolleybuses used numeric designations (1, 2, 3), later replaced by letters (A, B, C, D, E, F, G, H). Until 1989, the fleet consisted exclusively of Soviet-built ZiU-9 trolleybuses, 24 in total. The first Polish-built trolleybus, based on a Jelcz bus, was purchased in 1989. These were gradually replaced by mid-floor Jelcz PR110E and Jelcz 120MT models. In 1998, Tyskie Linie Trolejbusowe Sp. z o.o. was established as a limited liability company spun off from the local public transport enterprise, Przedsiębiorstwo Komunikacji Miejskiej, and took over trolleybus operations. In 2002, TLT introduced the first low-floor trolleybus in Tychy, a Solaris Trollino 12T. By 2008, six Solaris Trollino 12 vehicles of various subtypes had been purchased. In 2012 and early 2013, under the project "Modernisation of tram and trolleybus infrastructure in the Upper Silesian Agglomeration with accompanying infrastructure", TLT put 15 new Solaris vehicles into service. These featured the ability to run without overhead wires for up to 5 km, useful for road incidents or detours. Thanks to EU funding, high-floor Jelcz PR110E (used since 1983) and Jelcz 120MTE (used since 1994) vehicles were phased out. In April 2015, the last two Jelcz trolleybuses were withdrawn, and since then TLT has operated only low-floor vehicles. In June 2018, a contract was signed to build a trolleybus network on Sikorskiego Street with a new traction substation, enabling a route change for line E and the launch of new line G. Parts of the route without overhead wires are covered on battery power. In December 2018, deliveries began of three contracted Solaris Trollino 12 trolleybuses built on the fourth-generation body. These were equipped with lithium-titanate (LTO) traction batteries allowing up to 30 km without overhead supply, and were the first Tychy trolleybuses with passenger compartment air conditioning. In 2020, TLT added two Solaris Urbino 12 electric buses to its fleet, operating interchangeably with trolleybuses on line H, previously served by conventional buses. Electric buses also appear interchangeably with trolleybuses on lines A, C, and F. In early 2022, four Solaris Trollino 12S trolleybuses leased from MPK Lublin entered service. In April 2022, six modern Solaris Trollino 12 Electric vehicles were delivered, featuring dual bus-trolleybus homologation and LTO batteries allowing about 65 km without overhead connection; batteries are charged while running on the catenary. In December 2025, the first 6 of 18 new Solaris Trollino 12 vehicles were delivered, equipped with air conditioning, facilities for disabled and visually impaired passengers, an advanced passenger information system, driver assistance systems, and an AED defibrillator. They also have an additional battery drive enabling travel beyond the overhead network.
