The company is a member of Inekon group.

The joint venture between Škoda and Inekon was dissolved in 2001, after which Škoda continued to sell the 03 T, while Inekon formed a new partnership with DPO (Dopravní podnik Ostrava, the city transport company of Ostrava),[1] known as DPO Inekon, and in 2002 began selling a nearly identical version of the Astra, under the name Trio.

[2] The Trio is a three-carbody-section, four-axle (two-bogie) design, in which the low-floor area represents 50% of the entire vehicle floor area.

The Inekon 01 Trio is a single-ended (uni-directional) version, buyers of which have included (as of 2008) the transport agencies in Olomouc and Ostrava.

The first car was built in 2002, for Ostrava's tram system (DPO).
