  We present the photometric and spectroscopic analysis of three Type II SNe:
2014cx, 2014cy and 2015cz. SN 2014cx is a conventional Type IIP with a shallow
slope (0.2 mag/50d) and an atypical short plateau ($\sim$86 d). SNe 2014cy and
2015cz show relatively large decline rates (0.88 and 1.64 mag/50d,
respectively) at early times before settling to the plateau phase, unlike the
canonical Type IIP/L SN light curves. All of them are normal luminosity SN II
with an absolute magnitude at mid-plateau of
M$_{V,14cx}^{50}$=$-$16.6$\pm$0.4$\,\rm{mag}$,
M$_{V,14cy}^{50}$=$-$16.5$\,\pm\,$0.2$\,\rm{mag}$ and
M$_{V,15cz}^{50}$=$-$17.4$\,\pm\,$0.3$\,\rm{mag}$. A relatively broad range of
$^{56}$Ni masses is ejected in these explosions (0.027-0.070 M$_\odot$). The
spectra show the classical evolution of Type II SNe, dominated by a blue
continuum with broad H lines at early phases and narrower metal lines with P
Cygni profiles during the plateau. High-velocity H I features are identified in
the plateau spectra of SN 2014cx at 11600 km s$^{-1}$, possibly a sign of
ejecta-circumstellar interaction. The spectra of SN 2014cy exhibit strong
absorption profile of H I similar to normal luminosity events whereas strong
metal lines akin to sub-luminous SNe. The analytical modelling of the
bolometric light curve of the three events yields similar radii for the three
objects within errors (478, 507 and 608 R$_\odot$ for SNe 2014cx, 2014cy and
2015cz, respectively) and a range of ejecta masses (15.0, 22.2 and 18.7
M$_\odot$ for SNe 2014cx, 2014cy and 2015cz), and a modest range of explosion
energies (3.3 - 6.0 foe where 1 foe = 10$^{51}$ erg).
