In the long-baseline neutrino experiments, an interesting signature of sterile neutrinos could be the anomalous appearance of tau neutrinos in the near detectors, not expected in case of three-flavour oscillations. The expected sensitivities in the (sin22θμτ,Δm241 \sin^22\theta_{\mu\tau},\Delta m_{41}^2 ) parameter space, based on full MINOS+ Monte Carlo simulation and reconstruction, for total statistics of MINOS+ experiment will be presented. Also, the perspectives for the future long-baseline experiments will be discussed.
