Tatra-Yug K1 is a Ukrainian tram family based on Tatra T6B5. The trams were developed by former Ukrainian ČKD branch Tatra-Yug at Pivdenmash aerospace factory in Dnipro.

Types

K1

The development of the Tatra T6B5 modernization for Kyiv (hence the letter 'K' in the name)^[1] started in the late 90's, the first prototype was built in 2001 and sent to the capital for testing. In 2003 Tatra-Yug assembled two K1 trams with T6B5 bodies, they were sent to Donetsk. In 2004 the first K1 was returned to factory, the same year Tatra-Yug began the serial production of the facelifted K1.^[2]

In 2003–2008 Tatra-Yug supplied Donetsk with 25 K1 trams, which is the biggest amount of units per city. In 2004 5 units were received by Luhansk, where they worked until the tram network was closed in 2016. In 2006 the tram got a new control system. In 2006–2008 10 units were received by Odesa^[3] and 7 units were received by Mariupol, another 7 units were received by Mykolaiv but one of them has been returned to factory.^[4] In 2007 K1 got new doors and seats, while the original K1 prototype has been modernized to match the serial models and was sent to Konotop. In 2007–2008 Kryvyi Rih received 7 units^[5] and in 2008 Zaporizhzhia received one unit. In 2010–2011 Kyiv received 9 units and the final K1 was built in 2013 for Dniprodzerzhynsk (now Kamianske). Additionally in 2015 Mariupol received one K1 that was assembled for Kyiv in 2012 but was never delivered.^[6]

K1M8

In 2004 Tatra-Yug developed a three-section tram. Since 2006 the first two units were tested in Dnipropetrovsk (now Dnipro). In 2010–2012 Kyiv received four units of K1M8 including the original two.^[7]

K1M

In 2012 Tatra-Yug assembled the first semi-low-floor version of K1. Kyiv received 8 units in 2012–2015, Odesa got one in 2015^[8] and the final unit was sent to Mariupol in 2016.

K1T2

K1T2 was planned as a longer version of K1M8, however Tatra-Yug never built a single unit of it so it remains an unrealized project.

K1T3

The longest modification of K1 was supposed to be a five-section K1T3, but just like K1T2 no units of it were built.

K1M6

The development of the new modification of K1 began in 2015, Tatra-Yug hosted a competition for the best exterior design and chose the winner in 2016. July 1 the tram was introduced in Odesa. The single unit that was built in 2017 was tested in Kamianske before being bought by Kyiv in 2018.^[9]

K1E6

In 2018 Tatra-Yug took an order of Egyptian city of Alexandria to develop a narrow gauge version of K1. In 2018–2020 Tatra-Yug built a 15 trams for Egypt.^[10]
