  Experimental signatures of Majorana zero modes in a single superconducting
quantum wire with spin-orbit coupling have been reported as zero bias peaks in
the tunneling spectroscopy. We study whether these zero modes can persist in an
array of coupled wires, and if not, what their remnant could be. The bulk
exhibits topologically distinct gapped phases and an intervening gapless phase.
Even though the bulk pairing structure is topological, the interaction between
Majorana zero modes and superfluid phases leads to spontaneous time-reversal
symmetry breaking. Consequently, edge supercurrent loops emerge and edge
Majorana fermions are in general gapped out except when the number of chains is
odd, in which case one Majorana fermion survives.
