Loco 742 711-5 is the first of fifty EffiShunter 1000M locos ordered by CD Cargo from CZ LOKO to be out on the mainline. The EffiShunter 1000M is a modernization of the CD Class 742, following the well-known recipe which leaves only the frame and bogies of the original loco. 742 711-5 will be the prototype loco and serves to test all systems, including the on-board ETCS. Serial production is expected to start in October.

However, even though the locos are numbered in the 742.7 series, they will be considerably different to the Class 741.7/742.7 we already know from CZ LOKO. The EffiShunter 1000M numbering will start at 742.71x, starting a new number sub-series. The design of the loco is a compromise between the EffiShunter 600 (the body) and the EffiShunter 1000 (cabin).

Technical details include a maximum speed of 100 km/h, a CAT 3508C engine producing 1000 kW, a weight of 70 tonnes and a length over the buffers of 13.82 meters. Operating in multiple traction is possible, with the EffiShunter 1000, 1000M and Class 753.7. The locos will be equipped with ETCS.
