In the 1970s, the former Czechoslovak State Railways (CSD) had an urgent need for powerful diesel goods locomotives for medium-heavy shunting and mainline service. As a result, the lighter T 466.2 variant was designed based on the industrial locomotive type T 448. CKD in Prag manufactured nine series (each with slight technical differences) with 94 units from 1977 onwards and was in service with the CSD until 1986. In 1998, the class designation T 466.2 was changed to 742.
The type T3 wagon followed the type T1 wagon at the beginning of the 1990s. With a total length of 18.340 mm, the type T3 wagon is almost 2 m longer than its predecessor model and has a load limit of 69 t. So any registered trailer can be loaded and transported to its destination. However, the length is not optimal to carry containers, but still ideal for the transportation of 24'/26' swap bodies due to the higher load limit.
