The large-scale coordinate-tracking detector TREK for registration of inclined EAS is being developed in MEPhI. The use of large drift chambers (4000x508x112 mm$^3$) developed in IHEP for experiments at the neutrino channel of U-70 accelerator will allow to create a unique large-scale detector of 270 m$^2$ area for registration of multi-particle events at large zenith angles generated by ultrahigh-energy cosmic ray particles. The key advantages of these chambers are a large effective area (1.85 m$^2$), a good coordinate and angular resolution with a small number of measuring channels. Detector will be operated as a part of the experimental complex NEVOD, in particular, jointly with Cherenkov water detector (CWD) with volume of 2000 m$^2$ and coordinate detector DECOR. The first part of the detector named Coordinate-Tracking Unit based on the Drift Chambers (CTUDC) representing two coordinate planes of 8 drift chambers in each has been developed and mounted on the opposite sides of the CWD. It has the same principle of joint operation with NEVOD-DECOR triggering system so the main features of the TREK detector will be examined. Results of an examination of drift chambers and their electronics with new test benches, a calibration of the CTUDC and the first results of its joint operation with NEVOD-DECOR complex are presented.
